⚠ Subset of WCAG 2.1 — for full audit use axe-core or Lighthouse.

How to use

  1. Paste your HTML snippet into the input field.
  2. The checker instantly scans for common a11y issues such as missing alt attributes, empty buttons, unlabelled inputs, and invalid ARIA roles.
  3. Review each flagged issue in the results panel with the rule name and the offending element.
  4. Fix the HTML and watch the issue list update in real time.

Examples

  • Pasting <input type="text" placeholder="Email" /> flags a missing label — wrapping it with <label> clears the issue.
  • An <img src="/logo.png" /> with no alt attribute is reported as a violation; adding alt="Company logo" resolves it immediately.
