Instant Accessibility Checker
Check a page by URL or paste HTML against WCAG 2.1.
Check Accessibility Instantly
Run a quick WCAG 2.1 check on a live page by URL, or paste a snippet of HTML to test it directly. You get a score, the issues found, the automated checks that passed, and the criteria that still need manual review.
Two ways to check
- Enter a URL to fetch and scan a live page
- Paste HTML to test a component or email
- Instant results â no sign-up
- Every issue is mapped to a WCAG criterion
Score meaning
The score is the share of automated checks that passed. A high score means the structural basics are sound, but always confirm contrast, keyboard, and focus manually for a full picture.
Paste-HTML is fully private
When you paste HTML, the analysis runs entirely in your browser and nothing is sent anywhere â handy for testing unpublished pages, email templates, or single components. URL checks fetch the page server-side to get past browser cross-origin limits.
