Show HN: TraceRoot – Open-source agentic debugging for distributed services https://ift.tt/HncIgSm

Show HN: TraceRoot – Open-source agentic debugging for distributed services Hey Xinwei and Zecheng here, we are the authors of TraceRoot ( https://ift.tt/y0eF5RN ). TraceRoot ( https://traceroot.ai ) is an open-source debugging platform that helps engineers fix production issues faster by combining structured traces, logs, source code contexts and discussions in Github PRs, issues and Slack channels, etc. with AI Agents. At the heart are our lightweight Python ( https://ift.tt/ImpzvVF ) and TypeScript ( https://ift.tt/g27QUJT ) SDKs - they can hook into your app using OpenTelemetry and captures logs and traces. These are either sent to a local Jaeger ( https://ift.tt/nrh4yW5 ) + SQLite backend or to our cloud backend, where we correlate them into a single view. From there, our custom agent takes over. The agent builds a heterogeneous execution tree that merges spans, logs, and GitHub context into one internal structure. This allows it to model the control and data flow of a request across services. It then uses LLMs to reason over this tree - pruning irrelevant branches, surfacing anomalous spans, and identifying likely root causes. You can ask questions like “what caused this timeout?” or “summarize the errors in these 3 spans”, and it can trace the failure back to a specific commit, summarize the chain of events, or even propose a fix via a draft PR. We also built a debugging UI that ties everything together - you explore traces visually, pick spans of interest, and get AI-assisted insights with full context: logs, timings, metadata, and surrounding code. Unlike most tools, TraceRoot stores long-term debugging history and builds structured context for each company - something we haven’t seen many others do in this space. What’s live today: - Python and TypeScript SDKs for structured logs and traces. - AI summaries, GitHub issue generation, and PR creation. - Debugging UI that ties everything together TraceRoot is MIT licensed and easy to self-host (via Docker). We support both local mode (Jaeger + SQLite) and cloud mode. Inspired by OSS projects like PostHog and Supabase - core is free, enterprise features like agent mode multi-tenant and slack integration are paid. If you find it interesting, you can see a demo video here: https://www.youtube.com/watch?v=nb-D3LM0sJM We’d love you to try TraceRoot ( https://traceroot.ai ) and share any feedback. If you're interested, our code is available here: https://ift.tt/y0eF5RN . If we don’t have something, let us know and we’d be happy to build it for you. We look forward to your comments! https://ift.tt/y0eF5RN August 1, 2025 at 10:28PM

Show HN: I use AI to send myself personalized weekly recaps from my saved links https://ift.tt/wlFqM4T

Show HN: I use AI to send myself personalized weekly recaps from my saved links Sharing something that I’ve been working on: I made a save-later app for all my bookmarks. I save links throughout the week and, every Sunday morning, the app sends me a personalized recap with: -patterns and themes that connect my week to my broader interests -a nudge toward links I saved but never revisited -one reflective question to help me decide what else might be worth exploring I was inspired by older read-later apps like Instapaper. I wanted to make something minimalist, so it’s just a simple feed of your links (with tags and annotations linked to each link) and it is set up to ingest all kinds of content, not just text. I also did want it to be bloated as the full-fat AI stuff you see recently. So this is a simpler and more proactive take on the concept of a bookmarking app. Imagine if Pocket and Spotify Wrapped had a baby. I also personally enjoy using the chat to find links across subjects and sources with context, like “Show me the 5 links on travel i’ve returned to the most” or “all recipes with porcini mushrooms” or “show me everything on Topic X i’ve made the most notes on.” I’ve posted about this on HN before, always had great feedback. Happy to answer any questions. (I’m not technical, I'm a writer/ filmmaker.) https://tryeyeball.com/ July 31, 2025 at 04:38AM

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing https://ift.tt/ase2Kqg

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing Hey HN, We are Winston, Edward, and James, and we built Meka Agent, an open-source framework that lets vision-based LLMs execute tasks directly on a computer, just like a person would. Backstory: In the last few months, we've been building computer-use agents that have been used by various teams for QA testing, but realized that the underlying browsing frameworks aren't quite good enough yet. As such, we've been working on a browsing agent. We achieved 72.7% on WebArena compared to the previous state of the art set by OpenAI's new ChatGPT agent at 65.4%. You can read more about it here: https://ift.tt/ozD6ZbG . Today, we are open sourcing Meka, our state of the art agent, to allow anyone to build their own powerful, vision-based agents from scratch. We provide the groundwork for the hard parts, so you don't have to: * True vision-based control: Meka doesn't just read HTML. It looks at the screen, identifies interactive elements, and decides where to click, type, and scroll. * Full computer access: It's not sandboxed in a browser. Meka operates with OS-level controls, allowing it to handle system dialogues, file uploads, and other interactions that browser-only automation tools can't. * Extensible by design: We've made it easy to plug in your own LLMs and computer providers. * State-of-the-art performance: 72.7% on WebArena Our goal is to enable developers to create repeatable, robust tasks on any computer just by prompting an agent, without worrying about the implementation details. We’d love to get your feedback on how this tool could fit into your automation workflows. Try it out and let us know what you think. You can find the repo on GitHub and get started quickly with our hosted platform, https://ift.tt/WlemYCN . Thanks, Winston, Edward, and James https://ift.tt/IflwgDA July 30, 2025 at 07:41PM

Show HN: TanStack DB – Reactive DB with Differential Dataflow for TanStack Query https://ift.tt/3ChvI9Z

Show HN: TanStack DB – Reactive DB with Differential Dataflow for TanStack Query Hi HN, Kyle, Sam and the TanStack team here. We’ve been working on TanStack DB, an embedded, reactive client database for TanStack Query, and are proud to announce today that with the 0.1 release that it's now in BETA! TanStack DB plugs into your existing TanStack Query useQuery calls and uses Differential Dataflow to incrementally recompute only what changed, so updates stay sub-millisecond even with 100k rows. You get live queries, optimistic updates with automatic rollback, and streaming joins — all in the client! TanStack DB works with REST, GraphQL, WebSockets, and shines with sync engines like ElectricSQL or Firebase, letting you load large, normalized collections once and stream real-time changes into the client without manual bookkeeping. It sits on top of queryClient so you can adopt it incrementally, one route at a time. - Intro post: https://ift.tt/8jNuEdm... - Local-first sync via Electric: https://ift.tt/DineAYw... - Web starter with TanStack Start: https://ift.tt/7lzLRiU... - Mobile starter with Expo: https://ift.tt/7lzLRiU... - Project website and docs: https://tanstack.com/db - GitHub repo: https://ift.tt/LAfxP7h Try it out and let us know what you think! https://ift.tt/FdVaGsQ July 29, 2025 at 11:18PM

Show HN: Flyde 1.0 – Like n8n, but in your codebase https://ift.tt/8wkedF9

Show HN: Flyde 1.0 – Like n8n, but in your codebase Hi HN! I'm excited to share Flyde 1.0. A big update to the open-source visual programming tool I launched here in March of last year ( https://ift.tt/GOyLioa ). Since Flyde’s launch, there's been a huge rise in demand for visual builders, especially for AI-heavy workflows. Visual-programming shines with async and concurrency-heavy logic, which describes most LLM chains perfectly. A few months ago, I tried to capitalize on this trend by launching a commercial version of Flyde called Flowcode ( https://ift.tt/W27dkOu ). It didn't go well. I learned the hard way that Flyde’s strength wasn't just about flexibility or performance compared to tools like n8n. The real value was always how Flyde fits inside your existing codebase . The launch also helped me understand that there's still a big gap: no tool really covers the full lifecycle, from rapid prototyping to deep integration, evaluation, and iteration inside your own projects. So, over the last few months, I worked hard to polish Flyde: - Cleaned up and simplified the nodes API - Made it possible to fork any node for maximum flexibility - Launched a new online playground for quick experimenting and sharing ( https://ift.tt/Gyr1LtZ ) - Created a new CLI tool to speed up development and setup - Fixed a ton of bugs - Simplified the UI/UX to make it smoother and less confusing There’s still a lot of missing stuff. Better templates, docs, and nodes, but I think it’s finally stable and useful enough to give it another shot. My plan is to first make sure that Flyde is usable and valuable as an OS project, and then try to provide additional value via “Flyde Studio” - a SaaS that will help non-engineers iterate on Flyde flows from a web-app. Changes become a PR in the host repo. I'd really love some honest feedback and hear whether Flyde resonates with an existing pain/problem. Check it out here: Playground: https://ift.tt/Gyr1LtZ GitHub: https://ift.tt/QLFxdiJ Looking forward to hearing your thoughts! - Gabriel https://ift.tt/QLFxdiJ July 27, 2025 at 11:46PM

Show HN: Cronus – A Beautiful, Multilingual Cron Expression Editor https://ift.tt/EdzwDjx

Show HN: Cronus – A Beautiful, Multilingual Cron Expression Editor I’ve built Cronus, a tool that makes it easier to write and understand cron expressions across different languages and time zones. It shows human‑readable explanations of your cron jobs and adapts to multiple locales and time zones. You can preview schedules, tweak them visually, and copy/paste cron syntax for various environments. I’d love feedback from folks who deal with cron jobs regularly—what’s missing, what would make it more powerful, and whether this solves any pain points you’ve had. https://ift.tt/kT1Ecwj July 27, 2025 at 09:15PM

Show HN: LogMerge – View multiple log files in a merged view https://ift.tt/LYbjOqR

Show HN: LogMerge – View multiple log files in a merged view Hey HN! I needed a tool to view multiple log files in a merged view, and easily filter based on the specified fields. Spent a good amount of time searching, but couldn’t find any open source tool that quite did what I wanted. So, ended up building a custom solution instead (I would appreciate suggestions on tools that have similar functionality). I don't know much about GUIs (most all my PC based utilities are CLI) - but I did have the following: - I know enough Python to spot obviously wrong things - Some knowledge of how to make programs performant in general - ... and tokens to burn :) GitHub : https://ift.tt/J8Mo2xB Usage Video: https://youtu.be/37V_kZO2TLA Key Features: - Merge and display multiple log files in a single, chronologically ordered view - Live log monitoring with auto-scroll - Add files individually or discover them recursively with regex filtering - Plugin-based system to support any log format (easy to extend!) - Filtering: discrete values, numeric ranges, regex/text, and time-based queries - Color-coded file identification - Configurable columns and ordering - Built-in plugins for syslog, CANKing (CAN Bus monitoring tool), and another custom log format called dbglog. If you have any feedback or questions, let me know! Hope someone else finds it useful. https://ift.tt/J8Mo2xB July 26, 2025 at 04:23AM

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: Local Email Client for AI Horseless Carriages https://ift.tt/xHbGsYX

Show HN: Local Email Client for AI Horseless Carriages The AI Horseless Carriages article spurred a lot of conversation about how we should just be giving users the system prompt box [0], and we were pretty surprised that a bunch of email clients didn’t pop up following this pattern [1]. So we went ahead and created a local [2] email client that you can run that processes your inbox with your own handwritten rules. It lets you label and archive based on natural language rules. You can draft responses with your own drafting prompt, and there’s a “research sender” option that uses web search to get public info on a sender. You can customize any of the prompts to fit your needs. We’d love to hear what you think and PRs/issues are welcome!
