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)
