Show HN: Lunon – Instant model switching across LLMs https://ift.tt/867is5M

Show HN: Lunon – Instant model switching across LLMs Hey HN! We built Lunon to make LLM development way less of a headache. Ever wanted to see how different models handle the same prompt without all the setup hassle? That's what we fixed. Our API lets you compare Claude, GPT, Mistral and others in real-time with just a few lines of code. No more complex infrastructure or managing multiple API connections - we handle all that boring stuff behind the scenes. Plus, you can cut costs by intelligently routing requests to the right model for each task. Use the powerful (expensive) models only when you really need them. If you're building with LLMs and tired of the integration headaches, would love to hear feedback! https://lunon.com/ April 11, 2025 at 11:46PM

Show HN: I built a tool to manage and compare credit card rewards This is a free tool that helps you manage and visualize your credit card rewards across different categories. You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant. I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time. Would love feedback from the HN community! https://ift.tt/GaX07MN April 11, 2025 at 02:54AM

Show HN: Repo Roast – a real-time feed of the funniest comments on GitHub https://ift.tt/jTJsgWR

Show HN: Repo Roast – a real-time feed of the funniest comments on GitHub Hey HN - I'm Mason, and I'm excited to share a fun side project I've been working on recently: Repo Roast. For me, Github often feels like a serious (and sometimes soulless) place. I built this website to showcase the human, silly side of developers. Repo Roast is built on top of LLM-powered GitHub analytics tooling we’re developing internally at Merit Systems [0]. One of the historically cited weak points for LLMs has been their sense of humor. I found that with the right prompt, at scale, they mostly can _identify_ humor pretty well. We experimented with a couple of different models to tune the cost/effectiveness and eventually landed on a strategy where we have gpt-4o-mini do a very light filter pass to reduce the number of calls to GPT-4o to do the actual humor scoring. Interestingly, our first prompt attempts ended up surfacing wayyy more aggressively NSFW content, which is funny that this happens despite all the censoring that OpenAI is doing. So far we have processed the last 90 days of historical comments and continuously process new ones every hour. We theoretically can run this against a wider historical window given there is sufficient interest to justify the costs! Repo Roast is in no way intended to make you a better or more productive dev. You can use it as a leaderboard or hiring tool (if you’re looking for personality), or just a way to distract yourself! If you've had any funny Github interactions, I'd love if you shared them below. Cheers! --Mason [0] https://ift.tt/gbWsXQu https://ift.tt/yMjqRnN April 10, 2025 at 12:40AM

Show HN: Aqua Voice 2 – Fast Voice Input for Mac and Windows https://ift.tt/kSFuZUa

Show HN: Aqua Voice 2 – Fast Voice Input for Mac and Windows Hey HN - It’s Finn and Jack from Aqua Voice ( https://withaqua.com ). Aqua is fast AI dictation for your desktop and our attempt to make voice a first-class input method. Video: https://ift.tt/o3IHVuG Try it here: https://ift.tt/X6mExOb Finn is uber dyslexic and has been using dictation software since sixth grade. For over a decade, he’s been chasing a dream that never quite worked — using your voice instead of a keyboard. Our last post ( https://ift.tt/DOWXZNP ) about this seemed to resonate with the community - though it turned out that version of Aqua was a better demo than product. But it gave us (and others) a lot of good ideas about what should come next. Since then, we’ve remade Aqua from scratch for speed and usability. It now lives on your desktop, and it lets you talk into any text field -- Cursor, Gmail, Slack, even your terminal. It starts up in under 50ms, inserts text in about a second (sometimes as fast as 450ms), and has state-of-the-art accuracy. It does a lot more, but that’s the core. We’d love your feedback — and if you’ve got ideas for what voice should do next, let’s hear them! https://withaqua.com April 9, 2025 at 10:01PM

Show HN: I built a tool that deconstructs websites to reveal their tech stack https://ift.tt/E0S5bsu

Show HN: I built a tool that deconstructs websites to reveal their tech stack Hi HN, I built https://unbuilt.app to solve a problem I frequently faced as a developer: identifying the technology stack behind websites, especially those using newer frameworks and tools. While existing solutions rely on pre-saved data or signature databases, Unbuilt performs a fresh analysis by actually loading and examining the website code in real-time. This means it can detect cutting-edge technologies that often get missed by other analyzers. Technical details: - Uses Playwright to visit sites and analyze their resources - Queue-based architecture for handling concurrent requests - Optimized patterns for detecting modern frameworks (Next.js, Vite, React Compiler, etc.) - Dual-layer caching system for both performance and result sharing The tool is completely open-source and free to use. There are no premium tiers or usage limits. I built it because I believe developers deserve better tools for understanding the web ecosystem. I'd appreciate any feedback, particularly on detection accuracy and the types of technologies you'd like to see added. If you're interested in contributing, all pattern detection logic is designed to be easily extensible. Link to repo: https://ift.tt/wo0x69Z https://unbuilt.app/ April 9, 2025 at 10:57PM

Show HN: DrawDB – open-source online database diagram editor (a retro) https://ift.tt/bR8OtP4

Show HN: DrawDB – open-source online database diagram editor (a retro) One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take this project in. All of this was an accident. But now I feel like I'm missing out on not using this success. I have been thinking of monetization options, but not sure if I wanna go down that route. I like the idea of it being free and available for everyone but also can't help but think of everything that could be done if committed full-time or even had a small team. I keep telling myself(and others) i'll do something if i meet a co-founder, but doubt and fear of blowing this up keeps back. How would you proceed? https://www.drawdb.app/ April 9, 2025 at 05:50AM

Show HN: Latitude.sh Databases – Simple PostgreSQL DBaaS on Bare Metal https://ift.tt/XHelCbk

Show HN: Latitude.sh Databases – Simple PostgreSQL DBaaS on Bare Metal Hi HN, Gabriel here, one of the developers at Latitude.sh (we're a bare metal cloud provider). Over the past year or so, I've been the primary developer building Latitude.sh Databases – our take on a managed PostgreSQL service. The core idea was to offer a straightforward and competitively priced option for developers who need reliable PostgreSQL without overly complex configurations, leveraging the performance benefits of running directly on bare metal. It runs on our global bare metal infrastructure. Key features we've implemented include: * Built-in monitoring & connection pooling * IP Address Whitelisting (Trusted Sources) * Automated backups configured directly to your own S3 bucket (giving you control over storage and potentially costs) * An optional integration with Supabase, allowing you to use parts of their dashboard for enhanced usability with your database. Under the hood, it's built on Kubernetes running on our bare metal servers, using the CloudNativePG operator to manage the PostgreSQL instances. We've found this operator approach works well for handling stateful database workloads in K8s, challenging the old notion that databases don't belong there. The service stemmed from internal needs and early interest gathered from a waitlist (~300 signups). It's currently live and available for use. We're launching it here on HN because we'd genuinely appreciate your feedback on: * The overall developer experience and UI simplicity. * The current feature set (especially the S3 backup and Supabase integration). * Performance perceptions (given the bare metal base). * Our pricing model's competitiveness and clarity. * Any technical aspects of the implementation (running PG on K8s/bare metal). Happy to answer any questions you have! You can check out the product page here: https://ift.tt/UTs1LMq Thanks for looking! https://ift.tt/UTs1LMq April 6, 2025 at 11:30PM

Show HN: I made an AI Platform that gamifies applying to jobs https://ift.tt/ZjWFyqU

Show HN: I made an AI Platform that gamifies applying to jobs Hi there! I've created ApplyNinja, a platform that uses AI to help jobseekers apply to jobs faster and better. What differentiates ApplyNinja from the other "auto-apply" platforms is the trained AI model behind it. It learns from your resume and the jobs you apply to, and it provides better and better results. Currently, it serves as a helper for the entire application process: - Track & Monitor job applications - Generates Resume suggestions and highlights the parts that are not so good - Auto-fixes and generates a new resume based on the suggestions - Creates Cover Letters based on your resume and the job description - Generates Company Insights, scraping user reviews from Glassdoor, Indeed etc. - Generates Salary Insights so jobseekers have a negotiation leverage - Generates Technical Interview Questions based on the Job Description On top of all of this, it provides a gamified experience, because consistency is the key in applying to jobs. Me and my friends are using it daily and manage to land approximately 5-10 interviews/month as Software Engineers. I would really love any kind of feedback. Thank you very much! https://ift.tt/9X7cF20 April 6, 2025 at 12:09AM
