In their own words
Pa11y
Pa11y is a free, open-source set of tools for checking website accessibility. Its command-line interface loads a page for a one-off test and highlights issues, while Pa11y CI checks a list of pages in continuous-integration workflows. Pa11y Dashboard tests pages daily and graphs improvements or regressions over time. Pa11y Webservice supplies JSON data for the Dashboard or a custom dashboard-style front end. The package runs from the command line or Node.js, uses HTML_CodeSniffer by default, and can also use the axe test runner. WCAG2AA is the default CLI standard, with WCAG2A and WCAG2AAA selectable. Reports can be human-readable CLI output, CSV, HTML, JSON, or TSV. Configuration uses command-line options or JSON and JavaScript files, and local HTML files can be tested with an absolute path. Pa11y provides API access, scheduled scans, site-level scanning, and CI/CD integration across Linux, macOS, Windows, web, API, and self-hosted setups. Pa11y 10 requires Node.js 22.13.0 or newer on an even-numbered release.
