Accessive — Free WCAG Scanner

About

Accessive is a free, one-click accessibility checker. Click the toolbar icon and it scans the page you're currently viewing for WCAG 2.1 / 2.2 AA issues — instantly, right in your browser.
WHAT IT DOES

One-click scan of any page — no account, no signup, no setup.
Runs entirely in your browser. Nothing is sent to our servers.
Finds common accessibility issues: low color contrast, missing alt text, unlabeled buttons and form fields, missing ARIA, heading structure problems, and more.
Highlights problem elements directly on the page with colored outlines, so you can see exactly what and where.
Groups results by severity (Critical, Serious, Moderate, Minor) so you know what to fix first.

HONEST ABOUT WHAT AUTOMATED TESTING CAN DO
Automated checks catch roughly 30–40% of accessibility barriers. They're a fast, valuable starting point — but they are not a full compliance check. A passing scan does not mean a page is WCAG-, ADA-, or otherwise compliant. Keyboard navigation, screen-reader behavior, focus order, and whether content actually makes sense to a human still need manual review.
POWERED BY AXE-CORE
Scans use the open-source axe-core engine, a widely trusted accessibility testing library.

PRIVACY

The extension processes page content locally on your device to run the scan. It does not collect personal data, does not track your browsing, and does not transmit the pages you scan. See our privacy policy: https://accessive.app/privacy-policy
