Pa11y is an open-source automated accessibility testing tool that runs WCAG audits on web pages via a command-line interface or a Node.js API, using runners like HTML_CodeSniffer and axe-core on headless browsers. It reports accessibility issues in cli, JSON, or CSV formats and integrates into CI pipelines.
Use cases
- run automated accessibility audits on a web page from the command line
- check a site against WCAG2A/AA/AAA standards
- integrate accessibility testing into a CI pipeline
- get JSON or CSV reports of accessibility issues
- test pages with axe-core or HTML_CodeSniffer runners
- audit specific page sections with CSS selectors
When to choose
- you want a scriptable CLI or Node.js API for WCAG accessibility checks
- you need to gate deployments on accessibility errors in CI
- you want pluggable runners like axe or HTML_CodeSniffer with multiple report formats
When to avoid
- you need a GUI dashboard for tracking accessibility over time (use Pa11y Dashboard instead)
- you need full manual accessibility review or screen-reader testing rather than automated checks
- you are not working in a Node.js environment
