WebAbility Accessibility

Free, hosted accessibility scanner for AI coding agents. Combines WebAbility detectors, axe-core and HTML_CodeSniffer in one deduplicated report, with structured fixes marked mechanical, contextual or visual. Scan a URL or an HTML snippet, check color contrast and ARIA, generate a framework-aware fix, and verify the fix on the page. The anonymous scan tools need no key, with fair-use limits of 30 scans per hour and 10 AI fixes per hour per IP. A free WebAbility account unlocks the vision-based visual_audit and full site audits. Sign-in uses OAuth 2.1 with dynamic client registration.
