Accessibility Checker by WebYes– Free WCAG, ADA & EAA Testing in Chrome

Free accessibility checker Chrome extension for instant WCAG, ADA, and EAA compliance testing, directly in your browser, on any webpage.

Accessibility Checker by WebYes helps web developers, designers, QA teams, website owners, and accessibility auditors quickly identify WCAG accessibility issues without complex setup, DevTools dependency, or sign-in. Use it to spot high-impact accessibility issues early, validate page structure, and build more inclusive digital experiences.

✅ Instant accessibility testing in Chrome
Run a complete page-level accessibility audit in seconds. No configuration, no learning curve, just open a page and start testing.

✅ WCAG 2.0, 2.1 & 2.2 compliance checks (A, AA, AAA)
Detect accessibility violations mapped to WCAG 2.0, 2.1, and 2.2 success criteria at all conformance levels. Supports preparation for ADA, EAA, and Section 508 compliance.

✅ Color contrast checker
Check foreground and background contrast for text and UI elements like buttons and inputs, with instant WCAG AA and AAA pass/fail results shown on the page. Sample colors with the eyedropper, test alternatives in real time, and copy HEX values for quick use.

✅ Disability experience simulations
See your page through the eyes of users with different disabilities. Simulate dyslexia, low vision, and colour blindness conditions directly in the browser to understand real-world accessibility barriers.

✅ Landmark navigation
Visualize ARIA landmarks and page regions to verify that screen reader users can efficiently navigate your page structure without relying solely on headings or tab order.

✅ Best practices checks
Go beyond strict WCAG errors. Discover usability and inclusivity improvements that enhance real user experience, not just technical compliance.

✅ Visual issue highlighting
See exactly where accessibility issues occur on the page. Inspect affected elements without opening DevTools or writing a single line of code.

✅ Heading structure & focus order visualization
Visualize heading hierarchy and keyboard navigation (tab) order, two of the most frequently cited accessibility failures in WCAG audits.

✅ Alt text & image accessibility checks
Review all images alongside their alt text to verify accuracy and completeness across the page.

✅ Exportable accessibility reports
Download a full report of your audit results, including every issue mapped to its WCAG criterion and severity level, affected code snippets, and best practice recommendations. Ready to share with clients, developers, or stakeholders.

✅ Desktop & mobile testing
Test accessibility on both desktop and mobile page layouts without switching tools or devices.

✅ Privacy-first by design
- Runs entirely locally in your browser, no external requests
- Zero data collection or user tracking
- No sign-in or account required
