WCAG Accessibility Scanner
Audit a page against WCAG 2.1 and get fix code for every issue.
Scan a Page for WCAG 2.1 Issues
Enter a URL and this scanner fetches the page and audits its HTML against automated WCAG 2.1 checks across all four principles. Each issue is grouped by success criterion and comes with copy-paste fix code.
What it catches
- Missing alt text, labels, and link/button names
- Missing page language and title
- Duplicate IDs and broken heading structure
- Zoom-blocking viewport and positive tabindex
What needs a human
Color contrast, keyboard operability, and focus order depend on rendering and interaction, so they can't be judged from static HTML. The scanner lists them as manual-review items instead of guessing.
Automated testing is a starting point
Automated tools reliably catch roughly a third to half of WCAG issues â the structural, code-level ones. A complete audit also needs manual keyboard testing, screen-reader testing, and visual contrast checks. Use this scanner to fix the obvious problems fast, then verify the rest by hand.
How it works
The page is fetched server-side to bypass browser cross-origin limits, then parsed and analyzed in your browser. It scans the single page at the URL you provide â run it on each key template (home, product, form, article) for broad coverage.
