Axe DevTools enables dev teams to shift left with accessibility, catch 80% or more of issues while they are cheapest to fix, and reduce risk.

Test while coding

Analyze your static code as you type and get instant feedback on accessibility issues (like a spell checker for accessibility!)

  • Run pre-commit hooks to ensure that issues are caught before they are pushed to your repo.
  • Run checks from inside your favorite editor.

Test interactively in your browser

Focus on the issues that matter to you by scanning a full or partial page for accessibility.

Intelligent Guided Testing gives your team superpowers. AI-powered tests do the heavy lifting so your team can find more issues, faster.

Test in your pull requests

Using CI/CD tools like GitHub Actions, you can codify your accessibility policy and ensure that every pull request is checked for accessibility issues.

Easily add accessibility checks to your end-to-end tests–a single, one-time change to your config file.

Increase velocity and value across your entire SDLC
