Accessibility Checker
Accessibility Checker
Audit pasted HTML for common accessibility issues — missing alt text, unlabeled form inputs, heading hierarchy skips, missing lang attribute, ARIA misuse, non-semantic markup, and unreachable links — entirely client-side.
No input yet
Paste some HTML or load an example above, then click Check to audit it.
Heuristic, client-side DOM checks only — it complements but does not replace a full WCAG audit or dedicated tools like axe or Lighthouse. Nothing you paste here is transmitted over the network.
