A11y Agent

A11y Agent audits every page you visit for WCAG accessibility violations and displays results in a side panel as you browse. No manual scans — violations update automatically as the page changes, including during development with hot module replacement.

What it does
- Runs 90+ WCAG rules covering images, forms, ARIA, keyboard, landmarks, links, tables, color contrast, language, media, and document structure
- Audits the page, shadow DOM, and same-origin iframes
- Re-audits automatically on DOM mutations with chunked processing to avoid blocking the page
- Tracks multiple tabs simultaneously

AI fix suggestions
Select any violation to see the WCAG criteria it relates to and AI-powered remediation guidance using Chrome's built-in language model.

Developer tools
- Click "Show element" to highlight the offending element on the page
- Copy querySelector expressions for any violation
- Enable or disable individual rules from the settings page
- Toggle WCAG AAA level rules on or off

Localization
Rule descriptions and guidance adapt to your browser language. Currently supports English and Spanish.

Privacy
All auditing runs locally in your browser. Optional anonymous analytics can be enabled or disabled at any time. See our privacy policy at accesslint.com/privacy.
