About Marker.io
Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.
Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.
