TraceBug.init({ projectId: "my-app" });
Why developers choose TraceBug over Marker.io
✓Deep technical capture — DOM replay, console errors, network requests, and a repro timeline, not just an annotated screenshot
✓AI-agent ready — the report is machine-readable over a local MCP server; a failing Playwright test verifies the fix
✓Free and open source — Marker.io is a paid per-seat product
✓No account and no widget snippet approval process — install the extension and capture on any site
✓Local-first — evidence stays on your machine until you choose where it goes
✓Exports everywhere Marker.io sends feedback (GitHub, Jira, Linear) — plus PDF, HAR, zip, and AI-ready formats
When Marker.io might be a better fit
•Marker.io is built for CLIENT feedback — non-technical reporters annotating a live site into your PM tool with zero setup on their side
•Marker.io has two-way sync with project tools (status updates flow back to the reporter)
•Marker.io has team routing, forms, and SLA-style workflows agencies rely on
