Free website accessibility checker
Find detectable accessibility gaps before they become rebuild work.
Check a public page for observable HTML accessibility and mobile signals. The report shows evidence and practical fixes, while clearly separating automated checks from the manual WCAG testing a real accessibility review still needs.
What this checker covers
Useful signals without pretending automation equals compliance.
01
Document language
Whether the page exposes a language signal that browsers and assistive technology can use.
02
Image text alternatives
Whether images expose detectable alt-text coverage in server-delivered HTML.
03
Mobile viewport
Whether the page declares responsive viewport behaviour for mobile users.
04
Semantic structure
Whether detectable heading and document structure gives the page a usable information hierarchy.
05
Mobile readiness
Whether obvious mobile configuration gaps are visible in the public page source.
06
Manual testing boundary
Keyboard order, screen-reader behaviour, dynamic states and visual contrast still require browser-level testing.
