Accessibility Auditor

Accessibility Auditor performs comprehensive WCAG 2.1 and 2.2 compliance checks on web pages, components, and entire codebases. It identifies violations across all four WCAG principles — Perceivable, Operable, Understandable, and Robust — and provides actionable fix recommendations with code examples.

How It Works

1. Markup analysis — Scans HTML for missing alt text, improper heading hierarchy, missing form labels, and landmark region issues
2. ARIA validation — Checks ARIA roles, states, and properties against WAI-ARIA spec requirements
3. Color contrast — Evaluates text/background color pairs against WCAG AA and AAA contrast thresholds
4. Keyboard audit — Analyzes tab order, focus indicators, and keyboard trap risks
5. Report generation — Produces a prioritized violation report with severity levels (Critical, Serious, Moderate, Minor)

Best For

• Teams preparing for accessibility compliance deadlines (ADA, EAA)
• Reviewing pull requests for accessibility regressions
• Auditing third-party component libraries before adoption
• Training developers on common accessibility patterns

Standards Coverage

Covers WCAG 2.1 Level A and AA criteria fully, with partial AAA coverage. Includes checks from WCAG 2.2 additions including focus appearance, dragging movements, and consistent help patterns.
