A real free plan
Solo developers and small teams ship for free, forever. No 15-day countdown, no per-seat surprise at $39 a month. Upgrade only when your team grows.
From bug report to pull request
FeedBug's MCP server lets your AI agent read the bug, its console and network logs, the DOM around the pin, and trace it to the exact file to edit. Reporting is only half the loop, FeedBug closes the other half.
Linear, not a generic inbox
Tickets land in the right Linear team and project, attributed to the teammate who reported them, with status synced both ways. No extra triage layer to maintain.
Two minutes, one script tag
Paste a single script tag, connect Linear via OAuth, done. No SDK, no build step, works with any framework, and only loads on the domains you allow.
Frequently asked questions
Is FeedBug a good Marker.io alternative?
Yes. FeedBug covers the same core workflow as Marker.io (visual bug reports with screenshots, annotations, console and network logs, and session replay) while adding a free plan, Linear-native ticketing, and an AI MCP server that traces each bug back to the source code your agent should edit.
How is FeedBug cheaper than Marker.io?
FeedBug has a free-forever plan for solo teams and paid plans at 9 and 19 euros per month. Marker.io has no free plan and starts at 39 dollars per month after a 15-day trial.
Does FeedBug work with Linear?
FeedBug is built around Linear. You connect your workspace via OAuth, and every bug report becomes a Linear issue with the screenshot, diagnostics and a link back to the live pin, attributed to the actual teammate who reported it.
What is the AI bug tracing in FeedBug?
FeedBug ships an MCP server your AI coding agent (Claude Code, Cursor, Windsurf, VS Code) connects to. The agent can read the bug, its diagnostics and DOM context, and trace it to the source code to propose a fix. Marker.io currently uses AI only for translating issue text.
