Accessibility Checker by WebYes
Accessibility Checker by WebYes is a free Chrome extension that audits webpages for potential WCAG issues and provides tools for contrast, structure, focus order, alt text, and disability-experience review. It is designed for developers, designers, QA teams, auditors, and website owners who need browser-based accessibility checks.
Accessibility testing inside Chrome
Accessibility Checker by WebYes is a Chrome extension for developers, designers, QA teams, website owners, and accessibility auditors. It runs accessibility checks directly on an open webpage, helping users find potential WCAG issues during development or review without relying on a separate testing setup.
The extension combines automated page checks with visual inspection tools for contrast, landmarks, headings, keyboard focus order, images, and simulated disability experiences. It can also test desktop and mobile page layouts and download an audit report, but its results are intended as a testing aid rather than a complete legal or professional accessibility assessment.
Key features
WCAG conformance checks
Checks success criteria across WCAG 2.0, 2.1, and 2.2 at A, AA, and AAA conformance levels, with results associated with relevant criteria.
Color contrast testing
Tests text and interface-element contrast, provides WCAG AA and AAA pass/fail results, and includes an eyedropper, real-time alternatives, and HEX value copying.
Disability simulations
Simulates dyslexia, low vision, and color blindness conditions so users can inspect pages from different disability perspectives.
Structure and navigation views
Visualizes ARIA landmarks, heading hierarchy, and keyboard tab order to help review page structure and navigation.
Issue inspection and reports
Highlights affected elements and reviews image alt text; downloadable reports include issue severity, WCAG mapping, code snippets, and recommendations.
Who it is for
Development reviews
Run quick checks while building or revising a page, then use highlighted findings and WCAG mappings to identify issues before release.
Design validation
Inspect contrast, heading structure, landmarks, tab order, and simulated disability experiences while evaluating layouts and interaction design.
Quality assurance
Add a browser-based accessibility pass to QA workflows across desktop and mobile page layouts, with downloadable results for follow-up.
Accessibility audits
