Certvo

Certvo scans websites for WCAG 2.1 and 2.2 AA issues in a real browser (Playwright + axe-core), maps each finding to its WCAG success criterion and to EAA, ADA and Section 508, and suggests a code fix for the component that caused it. Scheduled re-scans catch regressions.

Free without signup: a 60-second homepage scan, a color contrast checker, an accessibility statement generator and a VPAT 2.4 generator. Free plan for one site; paid plans from $49/month. Certvo is not an overlay and changes nothing on your site.
