Show HN: Price Per Token – LLM API Pricing Data https://ift.tt/5DhC2bN

Show HN: Price Per Token – LLM API Pricing Data The LLM providers are constantly adding new models and updating their API prices. Anyone building AI applications knows that these prices are very important to their bottom line. The only place I am aware of is going to these provider's individual website pages to check the price per token. To solve this inconvenience I spent a few hours making pricepertoken.com which has the latest model's up-to-date prices all in one place. Thinking about adding image models too especially since you have multiple options (fal, replicate) to use the same model and the prices are not always the same. https://ift.tt/mNpJ3P8 July 25, 2025 at 06:09PM

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) https://ift.tt/Rh62LOi

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) Hi HN, I'm Gokhan, the founder of Brainbase Labs. Today we're releasing an early preview of our first generalist agent, Kafka. Kafka is the first AI employee, he comes with his own computer as well as his own email, phone and Slack so you can work with him just like you would with a regular employee. You can forward him emails, give him a call, tag him on Slack. We built Kafka as the basis for our other AI employees we will be releasing over the coming months. Kafka currently achieves 77.2% on the GAIA Level 3 benchmark, getting us closer to human performance at 87%. We've achieved this by creating a new type of planning algorithm called "structured planning" which allows Kafka to run very long term plans without getting sidetracked or hallucinating. Kafka can do some cool things, he can push code to AWS, direct its own commercial using Veo3 and do actual production tasks on Upwork/Fiverr. We're very keen to hear what HN thinks about Kafka, and how we can improve. Appreciate any feedback! https://ift.tt/Ywlb9zu July 23, 2025 at 10:21PM

Show HN: How Claude Code Improved My Dev Workflow https://ift.tt/LYaRVPb

Show HN: How Claude Code Improved My Dev Workflow I've been using Claude Code for the past month and it's transformed my productivity. Show HN: Title: A New Era for Software Development: AI Pair Programming Vs. Traditional Methods Today, let's dive deep into a topic that's revolutionizing the software development landscape - AI Pair Programming. By shedding light on the specific problems it solves, we will explore a real-life case study, and provide actionable insights to help you enhance your workflow. Firstly, let's understand the challenge. Traditional pair programming, while being highly beneficial, is often hindered by scheduling conflicts, differing skill levels, and varying coding styles. Here's where AI pair programming steps in. It leverages artificial intelligence to generate code suggestions, allowing developers to work more efficiently. Consider the case of CodeStream, a software startup. They adopted AI pair programming using GitHub Copilot. The results? Their development speed increased by 30%, and the number of bugs decreased by 25%. They also witnessed a significant improvement in code quality. This case study clearly illustrates the transformative power of AI in software development. So how can you incorporate this cutting-edge method into your workflow? Here are three actionable insights: 1. *Embrace AI tools:* Start by integrating AI-based coding assistants like GitHub Copilot or Kite into your development environment. These tools provide real-time, context-aware code suggestions, significantly reducing your coding time. 2. *Upskill:* AI pair programming is not about replacing human developers. It's about augmenting their abilities. Therefore, it's crucial to upskill and stay updated with AI advancements in your field. 3. *Continuously Test:* While AI tools can write code, they're not infallible. Regularly testing the AI-generated code ensures optimal performance. Now, where does the Keychron K8 Pro Keyboard fit into this workflow? For a start, it's a tool that enhances programming efficiency. With its hot-swappable keys and customizable layouts, developers can create shortcuts for frequently used coding commands, thereby streamlining their workflow. Its Bluetooth 5.1 feature allows for smooth What tools are you using to improve your coding workflow? Disclosure: Post contains affiliate links. July 23, 2025 at 02:57AM

Show HN: Compass CNC – Open-Source Handheld CNC Router https://ift.tt/ge2A4IV

Show HN: Compass CNC – Open-Source Handheld CNC Router Hey HN, I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process. The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts. What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for <$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope. We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.

Show HN: Lotas – Cursor for RStudio https://ift.tt/b1ueHNF

Show HN: Lotas – Cursor for RStudio Hey HN! We’re Jorge and Will from Lotas ( https://www.lotas.ai/ ), and we’ve built an AI coding assistant into RStudio (think Cursor for RStudio). RStudio is used by about 2 million data scientists and academics, but they currently lack a coding assistant within their IDE. Developers in other environments benefit from tools like Cursor and Windsurf, but R users don’t have any equivalent tools to speed up their workflow. Since ~80% of R programmers prefer to use RStudio over other IDEs like VSCode to write R code, we figured a tool like this one could be quite useful. Both of us were PhD students at Harvard. Jorge was in the biophysics program and Will was in the biostatistics program where most people used RStudio every day. We saw how integrated code assistants were taking off in other IDEs, but we noticed that the RStudio integrations were still lagging far behind. Many R users were copying and pasting code from ChatGPT to build their workflows, and this was clearly slow and fragile. To bring the Cursor-like experience to RStudio users, we built Rao ( https://www.lotas.ai/ ): a fork of RStudio with an embedded AI assistant that is aware of the user’s local context (both files and variable environment), can read and write files, can run code or commands, and can interpret textual or visual output. It works with any of the file formats already in RStudio (R, notebooks including RMDs and QMDs, Python, Stan, etc.), allowing R programmers to iteratively perform entire data analyses inside their preferred IDE. Other AI data science tools are either (1) built on the web or in environments people don’t already use, (2) are completely focused on python notebooks, or (3) are weak package-based assistants with limited functionality. Rao is exactly like the RStudio IDE that millions of data scientists already use, but it incorporates a powerful AI assistant and works with all the standard file types. You can download Rao at https://ift.tt/QiAdNqB , watch our demo on the homepage ( https://www.lotas.ai/ ), and work through some example use cases on our GitHub ( https://ift.tt/VQYrmLj ). We have a one-week free trial (no card required) and provide 500 queries/month for $20/month after that. We’d love to hear feedback from the HN community to make Rao as useful as possible! You can reach us at founders@lotas.ai. P.S. We have zero data retention (ZDR) agreements with OpenAI and Anthropic, but we currently recommend users do not input sensitive or regulated data like PHI into Rao until we sign BAAs with both model providers.

Show HN: The missing link of a bookstore's tech stack https://ift.tt/GsPca0o

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog post that lays out my vision here: https://ift.tt/FnsXVC8 The current iteration is like "data engineering as a service for books." A book is a powerful thing. I'm hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It's a crowded market but I've had fun making the bookselling app that I believe should exist. If you know any booksellers, please let them know about this! I'm onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It's frustrating to wait for two weeks for a point of sale provider to setup an integration. It's almost like they don't care about their customers. Some providers even require ethernet cables for their software...still partying like it's 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation. I'm currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can't focus on this project like I need to. I've gotten good validation from booksellers and other technically savvy folks in the industry (I've heard from two different companies that they've considered building something like this), so I believe I have something valuable. I'm not interested in funding from somebody who doesn't share my love for books or doesn't support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive. Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit. https://bookhead.net/ July 21, 2025 at 12:19AM

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief.

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans.

Show HN: I built a 2B-page search engine, independent of Google/Bing Hi HN, For the last 18 months, I've been working solo on building a completely independent search engine from scratch. Today, I'm opening it up for beta testing and would love to get your feedback. The project powers two public sites from the same 2-billion-page index: Searcha.Page: A session-aware search engine that uses a persistent browser key (not a cookie) for better context. Seek.Ninja: A 100% stateless, privacy-first version with no identifiers at all. The entire stack is self-hosted on a single ~$4k bare-metal EPYC server in my laundry room (no cloud, no VC funding). The search pipeline is a hybrid model, using a traditional lexical index for the heavy lifting and lightweight LLMs for specific tasks like query expansion and re-ranking. It's an experiment in capital efficiency and digital sovereignty—proving you don't need Big Tech APIs to compete. I’m looking for feedback on search result relevance, speed, and the clarity of the privacy models. Please try it out and let me know what you think.

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode https://ift.tt/1z8ldBa

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode I authored and developed an interactive children's book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story. Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story. The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend. Ten Dollar Adventure: https://ift.tt/gBufQrL Sample the Web Book (one complete storyline/adventure): https://ift.tt/zQUFdvc I couldn't muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.

Show HN: GitGuard - Painless GitHub PR Automations https://ift.tt/4pxaGPO

Show HN: GitGuard - Painless GitHub PR Automations Hey HN, Every team I've been on has cobbled together some sort of combination of GitHub branch protections and custom scripts to make sure that PRs conform to organization policies and best practices. Things like: - When {X} file is changed, require review from team {Y} - When a new db migration is added, ensure that a special set of tests pass - Require multiple approvals when the PR is very large - Add a special label to PRs that include breaking changes - Allow emergencies / hotfixes to break glass and bypass all of the above Most teams tend to start out with a little script running in GitHub actions to enforce all of these policies but it tends to get out of hand and become hard to maintain. PRs that should require scrutiny slip through the cracks, and others that should be allowed through are unnecessarily blocked. That's why I made GitGuard ( https://gitguard.dev/ ) GitGuard lets you write and maintain these policies in a custom DSL so simple it looks like pseudocode. The policies are checked on every single PR nearly instantly (no need to wait for a GitHub actions runner) and the results are reported in plain english. Right now policies can make simple assertions about PR metadata and take some stateful actions (adding labels, requesting review) but I'd love to hear more from HN about how GitGuard could be even more useful. https://gitguard.dev/ July 16, 2025 at 09:21PM

Show HN: StartupList EU – A public directory of European startups I’m from Europe, and when I spent a summer at Stanford, I saw how different the startup ecosystem is in the US. Everything there feels connected. In Europe, it’s scattered. Hard to discover early-stage startups unless you’re in the right city or network. So I built StartupList EU, a public directory where anyone can list or browse European startups. The goals is to contribute to the EU startup ecosystem more accessible and transparent for founders, investors and operators. What it does: - Founders can submit their startup for free - Each profile includes data like team size, category, funding, revenues, location, founders and more - You can search by country, industry, name, team size, country and business model - It works across the whole EU, not just big hubs like Berlin or Paris Right now there are 34 startups listed. More are coming in daily. I’m working on better filters, API access, and a weekly newsletter. Would love your feedback: - What data would be most useful to you? - What would make this genuinely helpful for founders, investors, or researchers? - If you are from US, what's your take about EU startup ecosystem? https://ift.tt/JeYyic3 July 15, 2025 at 01:54AM

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://langfa.st Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely.

See the website/docs/prompts.md and session-X.md files. I also started exploring some workflows for the LLM to execute, organized in the website/docs/tasks/ folder. I found it pretty handy to have the LLM document our work as we went and simply embedded the static site into the executable, along with all the music and logic. The whole project took me about a day for the backend. The C++ controller itself took only a few turns.

Show HN: VibeKin – Gated Discord Tribes via Personality Matching https://ift.tt/UG2c1Sk

Show HN: VibeKin – Gated Discord Tribes via Personality Matching I built an app that matches users to exclusive Discord communities based on a 25-question personality quiz. Inspired by HEXACO but with a novel fuzzy-clustering twist, it creates a "harmony genome" to gate access, ensuring tight-knit tribes (e.g., wellness or creative niches). Think Reddit but curated via psych. Launched to test the idea—feedback on algo, niches, or scaling? https://tgc.fly.dev July 12, 2025 at 07:32AM

Show HN: Transition – AI Triathlon Coach https://ift.tt/aJn1rZ6

Show HN: Transition – AI Triathlon Coach Hey HN, I’m Alex, a triathlete, dad, and software engineer. I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc). Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities. I built this because nothing else was flexible enough for my life, and I’m curious if others have the same problem. It’s in beta and free to try. I’d love feedback from the HN crowd — especially around the training logic, onboarding, or any ways to make it more useful for real athletes.

Show HN: Open source alternative to Perplexity Comet https://ift.tt/12EUG5V

Show HN: Open source alternative to Perplexity Comet Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://ift.tt/hOxTZWy --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad company, so no weird incentives. Your data stays on your machine. You can use local LLMs with Ollama . We also support BYOK (bring your own keys), so no $200/month plans. Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool! Short demo here: https://bit.ly/browserOS-demo --- How we built? We patch Chromium's C++ source code with our changes, so we have the same security as Google Chrome. We also have an auto-updater for security patches and regular updates. Working with Chromium's 15M lines of C++ has been another fun adventure that I'm writing a blog post on. Cursor/VSCode breaks at this scale, so we're back to using grep to find stuff and make changes. Claude code works surprisingly well too. Building the binary takes ~3 hours on our M4 Max MacBook. --- Next? We're just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!). But we strongly believe that a privacy-first browser with local LLM support is more important than ever – since agents will have access to so much sensitive data. Looking forward to any and all comments! https://ift.tt/peI5wWi July 10, 2025 at 11:03PM

Show HN: Activiews – A privacy-first fitness alternative for Apple users https://ift.tt/KHQbF0V

Show HN: Activiews – A privacy-first fitness alternative for Apple users Hi HN, I built Activiews as a fitness alternative for Apple users who want a simpler, more private, and more visual way to view their workouts, with a heavy focus on maps. The app reads from Apple Health and Watch data without requiring an account or sending anything to the cloud. I built it because I wanted a fitness app that: - Has no social network features - Does not store my data on their servers - Doesn't require an account or login - Stays lightweight and free of bloat - Is simple to use, with a focus on customizable workout visuals Core features: - Customizable workout maps and shareable cards - Flyover route animations - Calendar heatmap showing activity over time - Offline-first, data stays on device, no login/account needed - Dark/light themes, map styles, unit system, and accent color customizations - Reads data directly from Apple Watch - Localized in 13 languages - €0.99/month or €24.99 lifetime It’s built in Swift & SwiftUI using native APIs and focused on performance and privacy. I’d love your feedback, ideas, and comments. App Store: https://ift.tt/Do3kCap Website: https://activiews.xyz Thanks! http://activiews.xyz/ July 11, 2025 at 12:28AM

Show HN: MCP server for searching and downloading documents from Anna's Archive I was looking around for an MCP server that could connect Anna's Archive to Claude Desktop, as I wanted to be able to search and download books directly through the interface. I couldn't find any public implementations, so ended up building one myself. What it does? - It searches Anna's Archive by keywords. - It downloads books from search results. - It works directly in Claude Desktop through MCP. Check out the repository's README for detailed installation and configuration instructions. The code is fully open source and builds run on GitHub Actions for transparency. I figured I'd share, since I couldn't be the only one wanting this functionality! https://ift.tt/KUpMNj0 July 10, 2025 at 02:36AM

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram https://ift.tt/WKxIF8n

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram Hi HN! I'm Karl one of the co-founders of Stravu. ( https://stravu.com ) Using AI for work 24x7, we realized that four things would make AI more useful for us and a lot of other power users and teams: Editable output: AI gives output that is half right and our only option was to either keep chatting laboriously or copy it to a Google Doc. We made Stravu so you can edit what the AI says in chat or in an attached notebook. Everything editable. Approve AI changes: When AI makes a change to some text, you can't tell what changes. We put Red/Green diffs that you can approve into Stravu. Unify text, tables, diagrams: We were jumping between tools to work with AI on text, tables, diagrams, etc.. Just because Microsoft did that 30 years ago, doesn't mean it makes sense now. We made Stravu so you can work with AI across text, tables, diagrams, (and 2x2s, formulas, more soon) and have them inform each other. Actual multi-player team collab with AI: We couldn't collaborate as a team in AI (even with the ChatGPT Teams plan). We wanted to be able to chat with AI together as a team or see the changes AI was making in the canvas/notebook together and edit together. So we made Stravu support multi-player collaboration in every aspect... chats, notebooks, text, tables, diagrams..etc. Some of the use cases of our current Beta customers include: scrum teams doing feature/customer/competitive research and feature definition, account teams building vertical/geo/account plans, consultants and investment teams working on market/company analysis. We are currently in beta and actively iterating based on user feedback. Please try it out at: https://stravu.com We highly value your feedback! July 9, 2025 at 07:47PM

Show HN: OpenAPI mocks that don't suck – realistic test data, quick setup https://ift.tt/SmVCGPZ

Show HN: OpenAPI mocks that don't suck – realistic test data, quick setup Hi HN! I'm Ankit, the founder of Beeceptor, a request mocking and intercepting tool. This time, I built something new to address a pain I’ve personally felt (and heard from dozens of QA, frontend, and platform teams): making OpenAPI specs actually useful during development. API contracts just sit around as docs often. What if you could 'activate' them, instantly have a realistic, hosted mock server-with contract validation, smart test data, and early usage? So I made _Mockaroo for OpenAPI_, but with brains. It spins up a hosted mock server from your spec in one click. It: - Generates sensible context-aware, test data using FakerJS (e.g., age returns realistic numbers, not 10000) - Validates incoming requests against your contract definition and returns detailed, actionable error messages. - Supports JSON, binary, CRUD style API responses. - Gives a HOSTed API server URL, that's ready in a few seconds. - Helps frontend teams start testing before the backend is ready - Gives QAs a place to play, verify and run performance tests. - Enables the best developer experience, requiring no account setup and a working mock API server for experiments, and API cost savings. No local setup, no writing custom mock rules, no fuss. Just activate your OpenAPI spec, and your API starts “working” in seconds. Besides, Beeceptor shows live request logs, where responses can be overridden. Quick demo: https://www.youtube.com/watch?v=2vUD_B3aw5I --- Would love your thoughts, feedback, or use cases I haven’t thought of yet. Happy to share more technical details if there's interest. Thanks for reading! https://ift.tt/QxlqYdj July 9, 2025 at 01:00AM

Show HN: Gore – A Doom Engine Port in Go https://ift.tt/rou1GlY

Show HN: Gore – A Doom Engine Port in Go Hi HN, I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I'm trying to get rid of, and various other caveats. In the examples is a terminal-based renderer, which is entertaining, even though it's very hard to play with terminal-style input/output. The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read, and portable. Code and instructions are at https://ift.tt/Hz1aruX Would love feedback or thoughts. https://ift.tt/LXJFB8x July 8, 2025 at 06:29AM

Show HN: Life_link, an app to send emergency alerts from anywhere https://ift.tt/YRHP3pu

Show HN: Life_link, an app to send emergency alerts from anywhere 2-factor authentication terrorizes me. Many years ago, I was at a friend's house and decided to quickly pop downstairs to buy something. When trying to re-enter the building, the main gate had locked. And since my phone, keys, and any spare cash were all left upstairs, I was stuck outside. Thankfully, Google, at the time, allowed users to send SMSes (SMSs?) through the Hangouts app, which I did after logging into my account from an internet cafe. (Back then people weren’t constantly connected to Facebook, etc.) Since that day I feared being locked out of my accounts by 2FA, simply because my phone (and my access codes) weren't with me. And while it's true that today people are always connected to messaging apps, I wouldn't be able to reach any of them without me being able to log into mine. That’s why I built life_link, an app that allows my loved ones to reach me, wherever they are, without having to care about 2FA or even needing to log in. To do so, they simply need to reach the app on a secret (short) URL. I've since expanded life_link by creating a "generator" app that can produce a pre-configured, single-file application, ready to be deployed on any static site hosting service and decided to open-source it for other people who might find it useful. You can find the life_link project and learn more about it here: https://ift.tt/A5i2vYB July 8, 2025 at 02:29AM

Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics https://ift.tt/4vWMIzk

Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics https://ift.tt/4q7uhyi This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme. This is a complete recreation of the UI in JS; it all renders to a single canvas element. It's not a CSS theme, and not an emulator ported to JS. None of the code is written by Apple. I'll be happy to elaborate more in the comments, but the short version is the entire UI is defined outside the DOM using JS objects. Thus, every interface element - menus, windows, controls, and even typefaces - was recreated from scratch. There are no font files - I wrote my own typesetting system, which supports combining multiple text styles and generates new glyph variants on the fly. Many of the technical decisions I made were motivated by a desire to have this look the same in every browser. That's harder to do with the DOM and CSS, and why I moved as much logic as I could to JS. Also, the only part of the project outside of vanilla JS and standard web APIs is the Gulp toolkit, which I'm using as a minification/build tool. No vibe coding was used to make this! This is based on a UI from the 80s, and won't work well on your phone. If you insist on running it that way, turn on trackpad mode in the touchscreen settings panel of the preferences app. For best results, install it as a PWA (add it to your home screen). Also there are some odd Android bugs; the native touchscreen keyboard is currently broken, and there's an issue with the cursor when dragging windows. I realize there's not a whole lot to do within LisaGUI right now; I've got a big list of additional features and apps I'll be adding in the future. I've been working on this project for a while, and I'm eager to hear people's feedback and answer questions about it. https://ift.tt/IUp6Eyn July 7, 2025 at 12:02AM

Show HN: Claude Code History Viewer for macOS https://ift.tt/CgMaXhj

Show HN: Claude Code History Viewer for macOS *Claude Code History Viewer – A macOS Desktop App for Reviewing Claude Code History at a Glance* Hello everyone, I have a habit of reviewing my coding history when working with AI. It's important to trace back and understand "how did I get to this result?" Recently, while using Claude Code, I found it quite inconvenient to check the history in separate terminal tabs or editor windows. So I built a desktop app called *Claude Code History Viewer* using *Tauri + React + Rust*. ## Key Features & Highlights * *Claude Code Conversation History Visualization* When you install Claude Code, conversation logs are typically stored in `/Users/{username}/.claude` folder on macOS in JSONL format, organized by project. This app reads that data and displays commit/session history at a glance, just like viewing chat history. * *Richer Information Than Terminal* Visualizes much more data than what the terminal shows by default - including tree structures, detailed session breakdowns, code diffs, images, tool usage results, and more in various formats. * *Statistics: Token Usage by Project/Session, Daily Consumption, etc.* View various metrics on a dashboard, including how many tokens were used per project or session, daily token consumption, and other analytics. * *Automatic/Manual Folder Detection* Automatically detects the `.claude` folder by default, but allows manual specification if the folder doesn't exist or is in a different location. (Hidden folders can be shown in Finder with Shift + Cmd + .) * *Fully Local Operation & Privacy Protection* All data is processed locally only and never transmitted externally. * *Easy Installation & Usage* Ready to use right away with no registration or setup required. ## Development Motivation The process of reviewing AI coding results is crucial, but the existing terminal/editor approach was too cumbersome. I felt the need for a tool to view Claude's conversation history: * More easily * More comprehensively * More intuitively So I built it myself. How to Download & Install: You can download the latest DMG file from the release notes at the link and install it directly on your macOS system. ## Additional Notes * This is currently a *beta version*, so there may be bugs or missing features. I welcome honest feedback! * Open source (MIT license) - anyone can freely contribute to improvements. *This is a working application that you can try right now.* If you have any questions or ideas for improvements, please leave them in the comments! https://ift.tt/q4mVk0P July 4, 2025 at 03:02AM

Think of it as the opposite of ChatGPT. The coolest part? It includes a Postgres extension. You can now do: SELECT steadytext_generate('explain this query: ...'); And it will always return the same explanation. :) How it works: 1. Greedy decoding- Always pick the highest probability token (no randomness) 2. 8-bit quantization- Same numerics across all platforms It's easy to get started: uv tool install steadytext echo Hello | st https://ift.tt/Zk3I12R July 4, 2025 at 12:27AM

You can adjust the day thresholds and label colors in the workflow file, and choose whether labels update daily or only when they cross the next threshold. *Why?* I often lost track of how long tickets had been lingering, especially in older projects. A quick glance at the issue list or github project now tells us what’s fresh, what’s getting stale, and what’s officially ancient. It’s also handy for post-mortems: sort by red labels to see which bugs took the longest to close. *Link* https://ift.tt/sdl59P0... https://ift.tt/kA07Jyq July 3, 2025 at 03:15AM

You choose which memories sync and which stay private. Why this matters - Ask “What’s our roadmap now?” and “What was it last quarter?” — timeline and authorship are always preserved. - Change a preference (e.g. “I no longer use shadcn”) — assistants see both old and new memory, so no more stale facts or embarrassing hallucinations. - Every answer is traceable: hover a fact to see who/when/why it got there.

Show HN: Attach Gateway – one-command OIDC/DID auth for local LLMs https://ift.tt/WzLAplN

Show HN: Attach Gateway – one-command OIDC/DID auth for local LLMs We’ve been building local and on-prem agent workflows for open-source LLMs. Engines like Ollama or vLLM ship with no auth, so every team ends up writing the same JWT proxy. Attach Gateway is a single process that sits in front of any model server and handles the boring bits: - verifies OIDC / DID JWTs - adds X-Attach-User and X-Attach-Session headers so downstream agents share the same identity - optional /a2a/tasks/send endpoint for Google-style A2A hand-offs - mirrors prompts + completions to Weaviate (runs in Docker) One `pip install attach-dev`, export a token, run `attach-gateway`, and your local Ollama is protected in under 60 seconds.

Show HN: Query your Rust codebase and generate types for anything https://ift.tt/LgQ4tDh

Show HN: Query your Rust codebase and generate types for anything Hello HN! As a long-time professional Rust developer. I've always been frustrated by the difficulty and "hackiness" of producing bindings to other languages, whether a frontend, an FFI library, etc. Not just in Rust but in any language. After many years of trying existing solutions and trying to make my own, I've finally developed a solution I'm very happy with. RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum's `.route`, function definitions, and more, and then receive rich type information including all argument types, function paths, proc macro attributes, and more. Your Lua script can then read this information and emit an output file in any language of your choosing. Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solution! The code example is a bit verbose, so I encourage you to take a look at the repo's README. I look forward to hearing your thoughts, or any usecases you may come up with! https://ift.tt/qMOTg3f June 29, 2025 at 12:25AM

Show HN: GPU market is absurd! So I built a dashboard of pricing/restock trends https://ift.tt/dYNbrXT

Show HN: GPU market is absurd! So I built a dashboard of pricing/restock trends Hey HN! This idea started with me not being able to buy a GPU and constantly losing to bots/scalpers. I figured I'd use this as way to see how far I can get with 'vibe-coding and designing'*. The end result was pretty far! Here are more details of behind the scenes. In a future blog post, I'll detail behind the scenes process of building this. - The landing page is React/Typescript/Tailwind.css (which I've never used before) - The dashboard is based on Evidence.dev - which is SQL queries in Markdown + little bit of custom Javascript for chart formatting (again never used before :) - Just being able to get an idea like this in my head into existence would have taken me many months of Stack overflow/Google research to first learn React/Typescript/Javascript but this took about a month (~1-2 hr a day) * 'Vibe-coded' is often a misnomer i.e. people sometime think it's a magic pill. From building this I can tell you that you can't just will the site into existence like a genie's wish. It still took significant effort to guide the LLM, debug when things go wrong, need to have an idea of design and taste of what to build and how to make it look good, work on many iterations. There were probably 500 iterations between the first and the final iteration. https://ift.tt/b9XURxi June 28, 2025 at 12:32AM

Show HN: I built a JSON-RPC library for Zig with compile time reflection https://ift.tt/gyEKN3T

Show HN: I built a JSON-RPC library for Zig with compile time reflection Doing dynamic dispatching in a strict static typing language is hard. Something as simple as, map.put("add", add); map.put("hello", hello); fn add(a: i32, b: i32) i32 { return a + b; } fn hello() []const u8 { return "Hello World"; } is impossible because the value type of key/value of the map needs to be the same but all the function types are different. Calling functions with different number of parameters, different parameter types, and different return type dynamically is difficult. Other languages either use dynamic typing, runtime reflection, macro, or passing in one big generic parameter and let the function figure it out. In ZigJR, I use Zig's comptime feature to do compile time reflection to figure out a function's parameter types, return types, and return errors. I package them up into a specific call object and use the interface pattern to produce a uniformly typed object to be put into the map. It's not easy but doable.

Show HN: Magnitude – open-source AI browser automation framework https://ift.tt/OPzl8bT

Show HN: Magnitude – open-source AI browser automation framework Hey HN, Anders and Tom here. We had a post about our AI test automation framework 2 months ago that got a decent amount of traction ( https://ift.tt/Q2Wy746 ). We got some great feedback from the community, with the most positive response being about our vision-first approach used in our browser agent. However, many wanted to use the underlying agent outside the testing domain. So today, we're releasing our fully featured AI browser automation framework. You can use it to automate tasks on the web, integrate between apps without APIs, extract data, test your web apps, or as a building block for your own browser agents. Traditionally, browser automation could only be done via the DOM, even though that’s not how humans use browsers. Most browser agents are still stuck in this paradigm. With a vision-first approach, we avoid relying on flaky DOM navigation and perform better on complex interactions found in a broad variety of sites, for example: - Drag and drop interactions - Data visualizations, charts, and tables - Legacy apps with nested iframes - Canvas and webGL-heavy sites (like design tools or photo editing) - Remote desktops streamed into the browser To interact accurately with the browser, we use visually grounded models to execute precise actions based on pixel coordinates. The model used by Magnitude must be smart enough to plan out actions but also able to execute them. Not many models are both smart *and* visually grounded. We highly recommend Claude Sonnet 4 for the best performance, but if you prefer open source, we also support Qwen-2.5-VL 72B. Most browser agents never make it to production. This is because of (1) the flaky DOM navigation mentioned above, but (2) the lack of control most browser agents offer. The dominant paradigm is you give the agent a high-level task + tools and hope for the best. This quickly falls apart for production automations that need to be reliable and specific. With Magnitude, you have fine-grained control over the agent with our `act()` and `extract()` syntax, and can mix it with your own code as needed. You also have full control of the prompts at both the action and agent level. ```ts // Magnitude can handle high-level tasks await agent.act('Create an issue', { // Optionally pass data that the agent will use where appropriate data: { title: 'Use Magnitude', description: 'Run "npx create-magnitude-app" and follow the instructions', }, }); // It can also handle low-level actions await agent.act('Drag "Use Magnitude" to the top of the in progress column'); // Intelligently extract data based on the DOM content matching a provided zod schema const tasks = await agent.extract( 'List in progress issues', z.array(z.object({ title: z.string(), description: z.string(), // Agent can extract existing data or new insights difficulty: z.number().describe('Rate the difficulty between 1-5') })), ); ``` We have a setup script that makes it trivial to get started with an example, just run "npx create-magnitude-app". We’d love to hear what you think! Repo: https://ift.tt/uahTk2P https://ift.tt/uahTk2P June 27, 2025 at 12:00AM

Show HN: MCP Server for Tally – Create and Manage Forms with Claude https://ift.tt/Du2zIoO

Show HN: MCP Server for Tally – Create and Manage Forms with Claude I've built an MCP server for Tally that bridges the gap between their complex API and simple natural language commands. As someone with ADHD, I built this because context-switching between documentation, form builders, and actual work destroys my flow. Now I can stay in one conversation and just describe what I need. The interesting technical challenges: 1. API Complexity Abstraction Tally's API requires deeply nested objects for simple fields. An email field needs ~10 nested objects with UUIDs. I built a translation layer so users can just say "add an email field" in natural language, and the server handles the complex structure behind the scenes. 2. Safe Bulk Operations For destructive operations, I implemented a preview-then-confirm pattern. The server generates a confirmation token during preview that must be passed back for execution. This prevents accidental mass deletions while keeping the conversation flow natural. 3. Smart Rate Limiting The server monitors API responses and adjusts its behavior dynamically. When hitting rate limits, it automatically reduces batch sizes and adds delays between requests. Added randomization to prevent multiple instances from hitting the API simultaneously. 4. Type Safety Throughout Full TypeScript with runtime validation for both MCP messages and Tally API responses. This caught several undocumented API quirks during development. Performance notes: - Batch creation of 100 forms: ~12 seconds with batched operations - Individual creation of 100 forms: ~5 minutes due to rate limits - Human creation of 100 forms: probably a full week of mind-numbing clicking - Submission analysis across 10K responses: ~3 seconds The code is ISC licensed: https://ift.tt/TEBUmrF This particularly helps when you need to create multiple similar forms but your brain rebels at repetitive tasks. Curious if others are building MCP servers and what workflows you're optimizing for. Also interested in thoughts on MCP vs traditional CLI tools. The conversational interface is slower for simple operations but much better for complex, multi-step tasks where you might forget the exact syntax. https://ift.tt/TEBUmrF June 26, 2025 at 02:24AM

No SDK Some time ago I wanted to write a MCP server in Zig but found out there's no real JSON-RPC support in Zig, which MCP needs for communication. I ended up developing a JSON-RPC 2.0 library in Zig and more [1], which had its challenges. So I finally was able to put together a MCP server in Zig. It's built from scratch implementing the protocol messages from the MCP JSON schema. It's actually quite magical to have the LLM calling my MCP server [2]. The work is not too bad. Most of the hard work has already been done in the JSON-RPC library. [1] https://ift.tt/xebsDRJ [2] https://ift.tt/Fm7u9DJ... https://ift.tt/jlwmk1Z June 25, 2025 at 11:44PM

Show HN: Logcat.ai:AI-powered observability for Operating Systems(Android+Linux) https://ift.tt/W8b60Oz

Show HN: Logcat.ai:AI-powered observability for Operating Systems(Android+Linux) Hello HN! I'm an Android OS engineer. I've worked with AOSP and Linux kernels all my career and always wondered about lack of sophisticated tools to debug and analyze system-level logs. Always had to resort to manually skimming through large log files to find something I needed to. With the rise of LLMs and the AI-age, I felt it was a great opportunity to build something for OS engineers, which is what led to logcat.ai! We are building the industry-first observability platform for system level intelligence. Think "Datadog for operating systems" instead of applications. Currently, we support Android and Linux - more platforms on the way. With Android we offer: 1. logcat analysis: Ability to analyze logcat logs for root cause analysis of system issues with natural language search. Unlike, Firebase which is an app-level observability, logcat.ai provides intelligence at OS level spanning bootloader, kernel and framework layer. 2. bugreport analysis: As you know a bugreport is a super-verbose snapshot of an Android OS collected at a point of time. Analyzing these logs takes hours and sometimes even days. We are working to bring this down to minutes! Analysis of memory, cpu, process stats to infer memory pressure levels, system stress, and nail down the processes responsible for it, identify performance bottlenecks and memory leaks across the system. For Linux we offer: dmesg (kernel log) analysis to help identify issues at Linux kernel level. We plan to add support for different Linux distros with their own logging pretty soon. Our goal is to build a single-pane-of-glass observability experience for operating systems worldwide, something that's never been done before. Our website may not reflect all the features a.t.m but we have a lot of things cooking! Ask us anything. We are providing free beta access for a period of time. We'd love your feedback and comments on what you think about logcat.ai! https://logcat.ai June 24, 2025 at 10:53PM

Show HN: TNX API – Natural Language Interactions with Your Database https://ift.tt/CODRGBt

Show HN: TNX API – Natural Language Interactions with Your Database Hey HN! I built TNX API to make working with databases as simple as asking a question in plain English. What it does: - You write a natural language prompt (e.g., "List products with price > 20 USD") - Our system turns it into SQL and runs it - You get actual results, optionally visualized - Your data stays private – nothing is stored, the AI doesn‘t see it, and the API forgets immediately after replying Why I made this: Writing SQL for routine questions is https://ift.tt/Pxs9wDm still a blocker for many teams. I wanted a privacy-first, plug-and-play API that just works with natural language. TNX doesn’t just translate — it executes the queries and returns actual answers (not just SQL). Examples: - You ask: “Total sales by product category this year?” → TNX replies: [furniture: $43,000, electronics: $12,000] + “Want a chart for this?” - You ask: “Which customers didn’t order in the last 90 days?” → TNX replies with names or IDs and offers follow-up actions Notes: - Built on modern AI models (small + fast) - No need to send full database dumps – just metadata/config + real-time access - Easy API integration - (Bonus: If you should be interested, I‘d handle setup + customization for you) Try it out: https://ift.tt/Pxs9wDm (user name: „hi@tnxapi.com“, password „1“ (so it's harder to forget)) (example promts: - „Please give me the name, ShortDescription and price of product with idpk = 20.“ or - „Please list me all product prices from idpk 10 to 20.“ and then - „Please list me all product prices from idpk 10 to 20.“ (I copied some of my databases for this test, I am sorry for the data being in German xd)) Cheers, Lasse Tramann (Feel free to reach out to hi@tnxapi.com : ) ) https://ift.tt/Pxs9wDm June 24, 2025 at 12:48AM

Show HN: Pickaxe – a TypeScript library for building AI agents https://ift.tt/xwy4g1K

Show HN: Pickaxe – a TypeScript library for building AI agents Hey HN, Gabe and Alexander here from Hatchet. Today we're releasing Pickaxe, a Typescript library to build AI agents which are scalable and fault-tolerant. Here's a demo: https://ift.tt/x1tAp7q... Pickaxe provides a simple set of primitives for building agents which can automatically checkpoint their state and suspend or resume processing (also known as durable execution) while waiting for external events (like a human in the loop). The library is based on common patterns we've seen when helping Hatchet users run millions of agent executions per day. Unlike other tools, Pickaxe is not a framework. It does not have any opinions or abstractions for implementing agent memory, prompting, context, or calling LLMs directly. Its only focus is making AI agents more observable and reliable. As agents start to scale, there are generally three big problems that emerge: 1. Agents are long-running compared to other parts of your application. Extremely long-running processes are tricky because deploying new infra or hitting request timeouts on serverless runtimes will interrupt their execution. 2. They are stateful: they generally store internal state which governs the next step in the execution path 3. They require access to lots of fresh data, which can either be queried during agent execution or needs to be continuously refreshed from a data source. (These problems are more specific to agents which execute remotely -- locally running agents generally don't have these problems) Pickaxe is designed to solve these issues by providing a simple API which wraps durable execution infrastructure for agents. Durable execution is a way of automatically checkpointing the state of a process, so that if the process fails, it can automatically be replayed from the checkpoint, rather than starting over from the beginning. This model is also particularly useful when your agent needs to wait for an external event or human review in order to continue execution. To support this pattern, Pickaxe uses a Hatchet feature called `waitFor` which durably registers a listener for an event, which means that even if the agent isn't actively listening for the event, it is guaranteed to be processed by Hatchet and stored in the execution history and resume processing. This infrastructure is powered by what is essentially a linear event log, which stores the entire execution history of an agent in a Postgres database managed by Hatchet. Full docs are here: https://ift.tt/Nxr2qwe We'd greatly appreciate any feedback you have and hope you get the chance to try out Pickaxe. https://ift.tt/JqFZiPp June 20, 2025 at 09:37PM

Show HN: Good old emails and LLMs for automating job tracking So I spent the last few days building Jobstack. The logic is quite simple. You apply to jobs and you get emails, you trade emails back and forth from interviews, questions and others until the role is either accepted or you are rejected. Also easy to apply to hundreds of roles and not being to know where you stand easily. With Josbtack, you sign up, get a unique email and forward emails to the url. And it uses LLMs to extract company details , tries to find information online about them and presents that to you. Every email you forward becomes part of your timeline with the company. It also tracks rejection, offers from the emails too and gives you a nice stats dashboard amongst others. Using Gemini 2.5 pro right now. No data stored not in any way. After extraction, it’s discarded. Even “AI chats with the company” aren’t stored https://jobstack.me June 22, 2025 at 03:07AM

Show HN: Inspect and extract files from MSI installers directly in your browser https://ift.tt/qrcbR81

Show HN: Inspect and extract files from MSI installers directly in your browser Hey everyone! I'm excited to share a small web app I built that allows you to view and extract the contents of Windows MSI installers directly in your browser. It's essentially a web-based "lessmsi" powered by Pyodide. You can try it out at: https://ift.tt/yxJG1fE My motivation for building this was from part of my day job -- I often get Windows MSI installers and need to extract files while preserving the relative directory structure and filenames, as they would appear after a full installation. The existing tools I found were good but limited in which platforms they support: lessmsi works great on Windows, while msitools works for Linux/macOS. Neither is a truly cross-platform solution that works on any major OS. So we developed pymsi (a pure Python library, available on GitHub at https://ift.tt/t1ElQix ) to handle reading and extracting MSI files from Python. Then I realized that since pymsi has no native dependencies, it could potentially run in a web browser using Pyodide. After a bit of "vibe coding" and fixing some "hallucinated" functions/classes that don't exist in pymsi, the result was this client-side web app. If you need an MSI file to experiment with, older versions of PowerToys included the installer in .msi form, such as this one: https://ift.tt/2xUVukg.... Note that the underlying pymsi library hasn't been extensively tested against a bunch of MSI installers yet, so there might still be lingering bugs. If you come across any issues, please don't hesitate to report them in on the GitHub repository ( https://ift.tt/aFuhP0x ). I'd love to hear your feedback and answer any questions! https://ift.tt/yxJG1fE June 21, 2025 at 01:34AM

Show HN: Vpuna AI Search – A semantic search platform https://ift.tt/Mftw5r6

Show HN: Vpuna AI Search – A semantic search platform Dear HN Community, I am a long time fan and first-time contributor. I just launched a developer focused semantic search platform and wanted to share it with the community. The idea is simple: upload structured or unstructured documents, select the fields you want to index and tag as metadata, and instantly get a clean search API you can use in your own app. Here is what it currently supports: - Manage your own tenants and projects - Upload .json and .txt files (support for .pdf, .docx, .xlsx, .yml, etc. coming soon) - Expose 3 APIs: search, upload document (embeddings), and delete document - Manage your own API keys - Uses CPU based sentence-transformers/all-MiniLM-L6-v2 for embeddings ( support for other local and online models are coming soon) LLM summarization and Model Context Protocol (MCP) support are on the roadmap Why I built it: In my consulting work, I kept seeing client wanting to move beyond basic keyword search and integrate semantic search with optional summarization. Most existing tools are either too expensive, too restrictive, or require custom layers (like custom Python servers for pre processing queries and embeddings). I wanted something API first, developer friendly, and easy to self host or use out of the box. This is the first release, and I would love your feedback. Would you use this? What is missing for your use case? Here is the README with all the links https://ift.tt/FgWhS1O Thank you for your time. https://ift.tt/OLc8kq9 June 20, 2025 at 11:24PM
