TraceBug
Instant bug reports your AI agent can actually debug
Capture a browser bug in two clicks: session replay, console errors, network requests, screenshots, and a repro timeline in ONE offlinehtml file. A local MCP server lets Claude Code, Cursor, or Windsurf debug from real evidence. Free, MIT, no account.
Hey Product Hunt! 👋
I built TraceBug because I was living both halves of a bad loop: receiving bug reports that said "checkout is broken" with a cropped screenshot, and then pasting console output into Claude by hand to debug my own bugs.
TraceBug fixes both halves:
🐛 Capture — a free Chrome extension (or npm SDK) records what actually happened: session replay, console errors with stack traces, network requests, screenshots, and a millisecond repro timeline. Two clicks, one self-contained .html file that opens offline. No account, no server, nothing uploaded — there is literally no backend.
🤖 Hand it to your AI — npx -y tracebug mcp starts a local MCP server (stdio-only, zero network connections) so Claude Code, Cursor, or Windsurf can read the evidence directly. We published an unedited transcript of Claude going from crash to root cause in five tool calls: tracebug.dev/proof — I'd rather show you than tell you.
Honest limitations, so you don't find them the hard way:
The extension is Chrome-only today (npm SDK works in any app)
Replay is rrweb-based, so canvas/WebGL-heavy apps lose visual fidelity
TraceBug ships evidence, not an LLM — the AI investigation uses your own agent
It's MIT-licensed and free — the whole pipeline runs on your machine, which I think is the one thing cloud bug-reporting tools structurally can't copy.
Try it in 30 seconds without installing anything: tracebug.dev/try.html has intentional bugs waiting to be captured.
I'll be here all day — tell me what's missing, and I mean it. The roadmap after today is literally built from what early users say.
