Why developers choose TraceBug over Bugsnag
✓Complete evidence per bug — DOM replay, repro steps, console, network, screenshots in one offline .html
✓AI-agent ready — machine-readable over a local MCP server, plus a generated failing Playwright test to verify the fix
✓Zero infrastructure and zero event quotas — no API key, no server, no per-event billing
✓Deliberate capture — you record the bug that matters instead of triaging thousands of grouped events
✓Privacy-first — nothing leaves the browser; captured secrets are auto-masked
✓QA-friendly — testers capture with the extension (Chrome, Edge, Firefox), no code access needed
When Bugsnag might be a better fit
•Bugsnag monitors production passively at scale with error grouping and stability scores
•Bugsnag has server-side SDKs (Node.js, Ruby, Python, Go, etc.)
•Bugsnag has release tracking and deployment correlation
