Frequently Asked Questions

What is an accessibility overlay?▾

An accessibility overlay is a third-party JavaScript widget added to a website that claims to automatically fix accessibility issues. Common overlay vendors include accessiBe, UserWay, AudioEye, and EqualWeb. They typically add a toolbar icon with features like text resizing and contrast changes.

Do accessibility overlays actually work?▾

Most accessibility experts and disability advocacy organizations agree that overlays do not provide meaningful accessibility improvements. Automated tools can only detect 30-40% of WCAG issues, and overlays can fix even fewer. They often introduce new barriers for assistive technology users.

Can an overlay protect me from ADA lawsuits?▾

No. Multiple court rulings have found that the presence of an accessibility overlay does not constitute compliance with the ADA or WCAG. In fact, some organizations have faced lawsuits specifically because their overlay created additional barriers.

How does this detector work?▾

Our tool loads the target URL in a browser, scans for known overlay vendor scripts, DOM patterns, and global JavaScript variables. It then runs a comprehensive WCAG 2.2 AA audit using axe-core to show real accessibility issues that persist despite the overlay.

What should I use instead of an overlay?▾

Build accessibility into your website from the start. Conduct manual audits, train your development team on WCAG 2.2, integrate automated testing into your CI/CD pipeline, and test with real assistive technology users.

Which overlay vendors can you detect?▾

We detect accessiBe, UserWay, AudioEye, EqualWeb, MaxAccess, TruAbilities, Facil'iti, Recite Me, User1st, and ADA Compliance widgets. We continuously update our detection signatures as new vendors appear.
