Accessibility Checker Pro

Accessibility Checker Pro is a lightweight, high-impact Chrome Extension that performs instant, automated WCAG accessibility audits on any active web page with a single click. BUILT ON INDUSTRY-STANDARD TECHNOLOGY Powered by axe-core, the most widely-used accessibility testing engine developed by Deque Systems. All auditing runs locally in your browser with zero remote code execution and no data sent to external servers. KEY FEATURES: One-Click Accessibility Audits Click "Run Audit" and instantly scan any active web page for accessibility violations. The extension injects the axe-core engine locally and returns structured results in seconds. Circular Health Score Dial A prominent circular gauge displays your page's overall accessibility health score from 0 to 100. The dial animates smoothly and changes color based on the score: green for 90-100 (excellent), yellow for 50-89 (needs improvement), and red for 0-49 (critical issues found). Traffic-Light Impact Badges Every violation is classified by severity with high-contrast, color-coded badges: Critical (must-fix), Serious (significant barriers), Moderate (should be addressed), and Minor (low-priority improvements). Highlight on Page Click "Highlight on Page" on any violation card to smoothly scroll the offending element into view and apply a glowing, pulsing red outline animation directly on the live DOM. The highlight auto-removes after 3.5 seconds. Copy Fix Note Click "Copy Fix Note" to copy a structured accessibility fix suggestion to your clipboard, including rule ID, violation name, description, affected element selector, and a link to the Deque University reference. Export JSON Download the complete raw audit payload as a structured JSON file. Contains full violation data, impact levels, selectors, and HTML snippets ready for CI/CD integration or further processing.
