Website accessibility checker: find WCAG issues in seconds
Enter your website URL to get a scored accessibility report with checks across images, forms, navigation, color, and ARIA semantics.
We fetch and analyze your page's HTML. No data is stored.
How the accessibility scan works
Our scanner fetches your page HTML and runs 16 automated checks based on WCAG 2.1 Level AA success criteria. Each check is weighted by its impact on real users - missing alt text and form labels affect more people than missing ARIA roles, so they carry more weight.
