In their own words
axe-core
axe-core is a free, open-source accessibility testing engine for websites and other HTML-based interfaces. It is designed to run beside functional tests in unit, integration, browser, and other testing environments. Its rules cover WCAG 2.0, 2.1, and 2.2 at A, AA, and AAA levels, along with additional best practices. Deque says automated checks find an average of 57% of WCAG issues, while uncertain findings are marked for manual review. Installation is documented through npm or pnpm, with tests calling the axe.run() API. The API lists Microsoft Edge, Google Chrome, Mozilla Firefox, and Apple Safari; Internet Explorer 11 is deprecated. Chrome and Firefox are tested on every pull request. JSDOM support is limited, and color-contrast checks do not work there. axe-core uses the Mozilla Public License 2.0. Security updates are available for minor lines up to 18 months old. Vulnerabilities are requested by email, with a stated 24-business-hour response and no bug bounty.
