What the publisher says

From the Tracebug repository's README, as published. We do not edit it. Read it on GitHub

TraceBug

Capture the bug. Let AI fix it. Local-first, zero backend. One .html file — full replay, console errors, network requests, repro timeline — that your AI coding agent reads over MCP and fixes. Opens offline for humans too.

▶ Watch the 15-second demo · watch Claude debug a real bug · try it live in the sandbox

TraceBug is a local-first debugging assistant. Capture a bug → produce a single self-contained .html file → hand it to your AI coding agent (Claude Code, Cursor, Windsurf), which reads the evidence over a local MCP server and fixes it — or email/Slack it to a human dev who opens it offline. Every report also embeds a failing test the agent runs to verify the fix.

Every report opens with:

🔍 Possible Cause (high confidence): API POST /orders failed with 500 after clicking 'Place Order'
> TL;DR: TypeError thrown on /checkout when clicking 'Place Order' button

No accounts. No SaaS lock-in. Data stays in your browser by default.

Optional cloud sharing (built, UI-gated off by default): if you'd rather share a URL than a file, sign in once and get a share link with the same content. The code ships behind a feature flag (PHASE2-CLOUD); the Share button stays disabled until the portal is switched on. Local .html export is the supported sharing path today.

Works with any frontend framework: React, Angular, Vue, Next.js, Nuxt, Vite, Svelte, SvelteKit, Remix, Astro, or plain HTML.
