About This Tool

The WCAG Checker automates accessibility conformance testing by analyzing a target URL or uploaded HTML to identify violations against WCAG 2.1 and WCAG 2.2 criteria. It focuses on real-world aspects like color contrast, keyboard operability, semantic HTML, alt text, form labeling, and ARIA usage. The tool produces a per-page score and a prioritized list of issues.
Conceptual operation: it crawls the page, inspects DOM structure, computes contrast ratios, and validates navigation order and visible focus indicators. It does not render pages, but uses robust heuristics to approximate user experience. The results include a machine-readable dataset and a human-readable report with remediation suggestions and code examples.
Beneficiaries include frontend engineers, accessibility specialists, product managers, and QA teams. Unique value comes from actionable remediation guidance, per-page conformance scores, batch analysis across site sections, and export formats suitable for audits and ticketing systems. Use cases include pre-release checks, CI integration, and risk assessment for accessibility.

Frequently Asked Questions

Find Quick Answers

What is WCAG?

WCAG is the Web Content Accessibility Guidelines, a collection of criteria for making web content accessible to people with disabilities. The tool targets WCAG 2.1 and 2.2 success criteria, translating rules into automated checks and remediation guidance.

Which WCAG versions are supported?

The checker supports WCAG 2.1 and WCAG 2.2. It maps violations to specific guidelines, with version selectors to produce version-specific reports and remediation suggestions suitable for audits and compliance workflows.

Does it analyze dynamic content and ARIA attributes?

Yes. The tool analyzes DOM structure, ARIA attributes, alt texts, focus management, and keyboard navigation. It may miss user-experience aspects in highly dynamic content, so automated results are complemented by manual testing for final accessibility decisions.

Can I export results and integrate with CI?

Export options include JSON, CSV, and PDF reports. Outputs are designed for integration into CI pipelines and ticketing systems, enabling automated tracking of violations, remediation status, and audit-ready documentation.
