axe-core is an open-source accessibility testing engine for websites and HTML-based UIs, with rules covering WCAG 2.0/2.1/2.2 and ARIA best practices. It integrates into existing test environments to automate accessibility checks, and react-axe wraps it for dynamic analysis in React apps.
Use cases
- automate accessibility testing in my test suite
- check my web pages for WCAG violations
- find a11y issues in a React app
- run accessibility audits in CI
- detect ARIA misuse and missing headings automatically
- integrate accessibility checks with Selenium or Cypress
When to choose
- you want automated WCAG/ARIA accessibility checks inside existing test tooling
- you need a lightweight, widely adopted engine with browser and Node.js support
- you build React apps and want runtime accessibility warnings
When to avoid
- you need full WCAG compliance - automated tools catch only ~57% of issues and manual review is still required
- you need mobile app accessibility testing rather than HTML-based UIs
- you want enterprise reporting and monitoring rather than a testing engine
