SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Accessibility Audit helps teams ensure WCAG 2.1 AA compliance by evaluating keyboard navigation, screen reader compatibility, color contrast, ARIA usage, focus management, and semantic HTML across web interfaces.

Core Features & Use Cases

  • Comprehensive evaluation across WCAG principles: perceivable, operable, understandable, and robust.
  • Automated and manual audit workflow: automated scans with axe-core and Lighthouse, keyboard navigation checks, screen reader testing, and visual contrast reviews.
  • Structured findings reports with prioritized fixes and actionable guidance for focus management, color accessibility, ARIA patterns, landmarks, and dynamic content.
  • Use cases include pre-launch accessibility checks, post-feature audits, compliance reviews, and investigations prompted by user-reported accessibility issues.

Quick Start

Audit a web page for WCAG 2.1 AA compliance and generate a prioritized findings report with fix instructions.

FAQPage Schema
How do I audit a web page for WCAG 2.1 AA compliance?

To audit for WCAG 2.1 AA compliance, run automated scans with axe-core and Lighthouse alongside manual checks for keyboard navigation and screen reader compatibility. This workflow uncovers ARIA usage gaps and color contrast problems, generating a structured findings report with prioritized, actionable fixes.

What is the best way to check keyboard navigation and screen reader compatibility?

Checking keyboard navigation and screen reader compatibility requires a manual audit workflow that evaluates focus management, semantic HTML, and dynamic content updates. This approach identifies operability barriers and ARIA usage gaps that automated scans alone miss, producing reproducible fixes for assistive technologies.

When do I need an accessibility audit for my web application?

You need an accessibility audit during pre-launch checks, after building new features, or when conducting compliance reviews. It is also essential for investigating user-reported accessibility issues to ensure your web interface meets WCAG 2.1 AA standards for perceivable, operable, understandable, and robust content.

Can I use Lighthouse and axe-core to find ARIA usage gaps and color contrast problems?

Yes, you can use Lighthouse and axe-core to find ARIA usage gaps and color contrast problems through automated scans. These tools are integrated with manual visual contrast reviews and screen reader testing to evaluate focus management and semantic HTML across web interfaces.

Does an automated accessibility scan catch all WCAG 2.1 AA conformance issues?

An automated accessibility scan does not catch all WCAG 2.1 AA conformance issues. Automated tools like axe-core and Lighthouse must be combined with manual audit methodology, including keyboard navigation checks and screen reader testing, to uncover complex focus management and dynamic content barriers.

How do I generate a prioritized findings report for web accessibility fixes?

Generate a prioritized findings report by running automated scans and manual accessibility audits across your web interface. The resulting report structures actionable guidance for ARIA patterns, color accessibility, and focus management, ensuring WCAG 2.1 AA compliance with reproducible fix instructions.
