Bottom line: MarkLayer is the best free Marker.io alternative if you're willing to paste the share link into your tracker manually. There is no fully free option that replicates Marker.io's two-way Jira/GitHub sync. That's the paid moat.

Looking for a free Marker.io alternative? Marker.io is paid only and built around tracker integrations (Jira, GitHub, Trello, Asana, ClickUp). Below are the strongest free options for the annotation half of the workflow. None of them replicate the integrations.
Free, open-source Chrome extension for visual annotation. No native integrations. Paste the share link into Jira, Linear, GitHub Issues. Real-time live cursors.
Best for: Teams happy to paste links manually and want zero billing.
Free tier with usage limits. Auto-captures console errors, network logs, browser metadata. Closer to Marker.io's bug-report style than MarkLayer.
Best for: Engineering teams that need browser metadata in bug reports.
Paid visual bug tracker with Kanban board and integrations. Direct competitor to Marker.io.
Best for: Teams shopping the paid bug-tracking category.
Free if you already use GitHub. Annotate a screenshot in any tool, attach to issue. Manual but zero new SaaS.
Best for: GitHub-native teams with low report volume.
MarkLayer is free, requires no sign-up, and works on any webpage. Recipients of your share links don't need to install anything.
