Lighthouse Accessibility Audit

Publisher: Google Chrome DevelopersLast checked: 2026-07-21

Lighthouse is built into Chrome DevTools and can run alongside performance and search audits. It is convenient for repeated checks while a page or component is being changed.

Limitations: Its accessibility score covers only tests that can be automated. A high score can coexist with serious usability problems that require keyboard, screen-reader, cognitive, and task-based testing.
