Supported WCAG Versions & Browsers

Use this page as a reference for supported WCAG version selection and browser-related considerations across Accessibility workflows.

Supported WCAG coverage

Current Accessibility docs reference support for these WCAG targets:

WCAG 2.0 A
WCAG 2.0 AA
WCAG 2.1 A
WCAG 2.1 AA
WCAG 2.1 AAA
WCAG 2.2 A
WCAG 2.2 AA

Browser considerations

Accessibility web workflows are optimized for Chromium-based browsers. Using current supported browser versions improves compatibility for DevTools and automation-related scans.

Important caveat

For Playwright Accessibility Automation, Chrome should be used instead of pw-chromium because the required extension does not load reliably in bundled Chromium sessions.
