  • axe DevTools — Automated accessibility testing for common WCAG issues.
  • Accessibility Insights — Automated and guided manual accessibility checks.
  • WAVE Evaluation — Visual accessibility evaluation that helps identify issues in page content and layout.

Other tools and checks

Use these tools for specific accessibility checks and additional manual testing. They require some manual intervention eg: XYZ...

  • Blur — Simulate blurred vision to check whether key content remains visible.
  • Contrast Checker — Check text and colour contrast.
  • HeadingsMap — Check the structure and hierarchy of headings.
  • Lists — Check the structure and accessibility of lists.
  • Resize text — Check how content works when text is resized.
  • Target size — Check whether interactive elements are large enough to use.
  • Text spacing — Check how content works when text spacing is increased.

Specialist testing

Some accessibility testing requires specialist knowledge or assistive technology.

  • Screen readers — Use screen readers such as NVDA, JAWS or VoiceOver to understand how people who rely on them navigate your content.
  • VoiceOver — Apple's built-in screen reader for macOS and iOS.

Understand test results

Accessibility testing tools cannot identify every accessibility issue and can sometimes produce false positives or give false assurance.
