A11yInspect vs Axe DevTools

A11yInspect is a browser extension that works with the Inspect tool in DevTools to assess web-page accessibility against WCAG 2.2. Automated checks cover more than 600 issues across 30 Success Criteria, with a stated false-positive rate below 1%. Results classify findings as Fails, Validates, or Suggestions and map them to criteria and severity. Supported standards include WCAG, Section 508, EN 301 549, GIGW 3.0, and IS 17802. Manual review tools include bookmarklets for headings, tab order, grayscale, target size, text spacing, and forms, as well as a color contrast checker. The extension is available for Chrome, Edge, and Firefox and can examine a page or a specific element. Pages can be tested in any language, although the interface is English-only; the extension is for desktop browsers and cannot be used on mobile. The Free plan allows unlimited webpage testing without login or a credit card. Pro costs $120.00 per year and includes a 30-day trial without a card; users move to Free if they do not subscribe when it ends.
