axe DevTools
Verified working Sep 16, 2026
A browser-based scanner for catching common WCAG accessibility issues.
axe DevTools is a Chrome extension for checking web pages for accessibility problems while you browse or develop. It runs automated accessibility scans, highlights affected page elements, and helps teams identify issues that should be fixed before release.
Why it stands out
- Runs directly in the browser, so issues can be checked on local, staged, or authenticated pages.
- Built around the widely used axe accessibility testing engine.
- Designed for developers and testers rather than only accessibility specialists.
- Pairs automated findings with element-level context that is useful for fixing code.
Good to know
- Automated scans cannot confirm every accessibility requirement; manual keyboard, screen reader, and usability checks are still needed.
- The listed product is a Chrome extension, so teams using other browsers may need a different version or tool.
- Some advanced axe DevTools capabilities may require a paid Deque plan or account.
