    Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer…

    Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). *…

    Show HN: Boardzilla, a framework for making web-based board games Tldr: We’ve made a framework for web-based board games. You can try out some games over at https://boardzilla.io, or you can take a look at https://docs.boardzilla.io to learn more about how to develop your own game. Source is available at https://github.com/boardzilla Hey y’all. My brother and I have made a framework for board games. During the pandemic we started to look at BGA but got discouraged by how old-fashioned the tools were and how cumbersome the development process was. We set out…

    Debugging a crash can sometimes feel like a noir detective story: following faint clues, chasing red herrings, and eventually hitting the moment where the whole case finally makes sense. I leaned into that idea and built Fatal Core Dump, a small game where the investigation is real crash debugging. The game gives you a Linux binary, its core dump, a source file, and some logs. You solve the mystery by debugging it. The premise: an engineer dies when an airlock on an asteroid mining station opens unexpectedly. Your job is to determine whether it was a simple software bug or something more…

    FlowLens▲134

    Hi HN, We often run into this with coding agents like Claude Code: debugging turns into copy-pasting logs, writing long explanations, and sharing screenshots. FlowLens is an MCP server plus a Chrome extension that captures browser context (video, console, network, user actions, storage) and makes it available to MCP-compatible agents like Claude Code. You can try it here: https://magentic.ai/flowlens Any feedback—good, bad, or brutal—is welcome.

    Hi All, this is Shardul here - I am the co-founder of Videobug. https://bug.video We are super excited to share Videobug with you. Videobug records run time code execution so that developers can watch it line by line as frequently as they want, right in their IDE. It takes away the pain of recreating exact conditions that led to a bug and saves developer time in every bug squash. Parth (my co-founder) and I have worked on multiple production grade applications in startups and enterprises. We used Logrocket, Sentry, and Datadog for logging and found ourselves adding more logs after…

    Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. It’s called Jam (jam.dev) and it prevents product managers (like I used to be) from being able to create completely vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. I used to write in the ticket that something didn’t work— only to lead to a ton of confusion by the engineer what I meant by “didn’t work”. Was the button unresponsive? Did the page crash? Did it return an error? Or like sometimes I thought…

    Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

    I built FlouState because "4 hours of coding" tells you nothing. Was it 4 hours debugging or 4 hours building features? Very different. It's a VS Code extension that automatically categorizes your coding into: Creating (new features), Debugging (fixing issues), Refactoring (improving code), or Exploring (learning codebase). Example: Yesterday I "coded" 6 hours but it was actually 3.5h debugging a race condition, 1.5h refactoring, 0.5h tests, 0.5h exploring. Traditional time trackers just show "6 hours in TypeScript." Technical: Tracks file changes, debug sessions, and edit patterns locally.…

    Hey HN! Esolang Park is an online visual debugger interface for esoteric programming languages, that I've been working on for the past few months. For every supported language, Esolang Park provides the powerful Monaco code editor, syntax checking, debugging functionality and a visualisation of the runtime state. The core is language-agnostic - a "language provider" only needs to implement the esolang's parser, interpreter and visualisation UI (and some other little stuff). Apart from trying to boost DX for esolangs, the idea is for this to grow into a platform where people can discover and…
