2026-02-25 — 11 min

Choosing the Right Audit Tool

Automated tools are essential for initial accessibility diagnostics but vary in focus and capability.

Comparison Table

RGAA Test: only RGAA-specific tool, calculates compliance rate, free. WAVE: visual error overlay, intuitive for non-techs. axe DevTools: technical precision, CI/CD integration, developer-focused. Lighthouse: built into Chrome, limited coverage (~40 rules).

RGAA Test (rgaa-test.fr)

The only tool specifically evaluating RGAA 4.1 criteria with compliance rate calculation, exportable reports for accessibility statements, and French legal context.

Recommendation

Use RGAA Test for RGAA compliance evaluation, axe DevTools for daily development, WAVE for non-technical awareness, and manual tests (keyboard + screen reader) for the remaining 60-70%.

No automated tool detects 100% of errors. Combining automated tools and manual testing is essential for complete evaluation.
RGAA Test is the only tool specifically designed to evaluate RGAA 4.1 criteria. Other tools evaluate WCAG but not RGAA specifically.
For initial diagnostics and regular monitoring, yes. RGAA Test, WAVE, and free axe cover main needs. Premium versions add advanced features useful for large organizations.
No. Lighthouse tests only about 40 rules of 106 RGAA criteria. A 100 score doesn't guarantee compliance. Supplement with RGAA Test, manual keyboard, and screen reader testing.
