IconVault's A11y Scanner runs a static accessibility scan on HTML you paste in. It flags the most common real-world issues: missing alt text on images, empty links and buttons, unlabeled form inputs, a missing lang attribute, heading order problems, duplicate ids and risky inline color contrast, each grouped by severity with counts and element descriptions.

The scan is instant and runs 100% in your browser, so your markup is never uploaded or stored. It is free to use with no signup. Be honest about its limits: it checks static markup only and does not replace tools like axe or Lighthouse, keyboard walkthroughs or testing with an actual screen reader.
