GitHub Accessibility Scanner Integration

What Is the GitHub Accessibility Scanner?

The GitHub Accessibility Scanner (github/accessibility-scanner@v2) is an official GitHub Action that:

• Scans live URLs for accessibility barriers using axe-core in a headless browser
• Creates trackable GitHub Issues for each finding, with affected element, WCAG criterion, and remediation guidance
• Optionally assigns issues to GitHub Copilot for AI-powered fix suggestions and PR creation
• Caches results across runs for delta detection (new, fixed, persistent findings)
• Supports authenticated scanning (login flows, SSO, passkeys via Playwright auth context)
• Optionally captures screenshots and attaches them to filed issues

Current version: v2 (public preview)
