Free accessibility checker

Most "free" accessibility checkers gate the results behind an email or show you a vague score. This one does not. Paste a URL below and you get the real findings, every failing element outlined, with the WCAG criterion and how to fix it.

What this checker does

It loads your page in a real Chrome browser, runs the open-source axe-core engine against WCAG 2.2 Level A and AA, and shows you exactly what fails. Every issue is outlined on a screenshot of the page, grouped by severity, and tied to the success criterion it breaks. You can share the report by link or export the findings as Markdown or JSON to hand to a developer or an AI coding agent.

How it is different from the others

  • No email wall. Results appear immediately. Nothing is gated behind a signup.
  • Real browser rendering. It tests what your JavaScript actually produces, not just the raw HTML, so it catches issues in single-page apps and dynamic content.
  • Honest about limits. Automated checks cover the machine-testable subset of WCAG. Items that need a human are flagged for review, never hidden or counted as passes. It will never show you a fake "compliant" badge.
  • It resolves gradient contrast. Where most tools give up on text over a CSS gradient, this measures the worst-case contrast and gives a real pass or fail.

Beyond a one-off check

A single scan tells you where you stand today. Accessibility drifts as your site changes, so for ongoing coverage you can monitor pages on a schedule and get alerted when a new issue appears, check work in CI with the command-line tool, or audit pages right in your browser with the Chrome extension. The one-page scan stays free.

Frequently asked questions

Is this accessibility checker actually free?

Yes. The single-page scan is free with no signup and no email. Paid plans add monitoring, multi-page audits, and AI features, but the checker itself is free to use.

Do I need to install anything?

No. Paste a URL in the browser and it scans. There is also an optional Chrome extension and a command-line tool for developers.

Which standard does it check against?

WCAG 2.0, 2.1, and 2.2 at Level A and AA, using axe-core, plus best-practice rules reported separately.

Will it tell me my site is compliant?

No tool honestly can. It clears the machine-testable issues and tells you what still needs manual review. Full compliance requires a human pass too.
