What Makes a Good Accessibility Scanner?

Looking for the best accessibility scanner? The strongest ones don’t just flag issues. They help you actually fix them and prove compliance over time. 

An accessibility scanner tests your website against WCAG, the technical standards U.S. courts and the DOJ reference for ADA compliance. However, no automated tool catches every issue. Some WCAG criteria can only be verified by a person, like whether alt text is meaningful, whether error messages are clear, or whether keyboard navigation works end-to-end. The best scanners combine automated detection with human testing. 

Here are three things to look for. First, look for automated scanning plus fixes. A tool that identifies issues and helps resolve them, not one that just hands you a report. Second, look for human testing alongside automation, because the issues automated scans miss are usually the ones that get sites sued. Finally, look for ongoing monitoring, since websites change every day, and a one-time scan goes stale fast.

The best scanners bring all three together instead of making you stitch tools together. That’s the approach behind platforms like AudioEye, which combine automated scanning, expert audits, and continuous monitoring in a single place.
