Web accessibility overlays don't work — here's what actually does

Accessibility overlay services like accessiBe and UserWay market themselves as a one-click fix for ADA compliance. They promise that a single line of JavaScript will instantly make your website accessible to users with disabilities, protecting you from lawsuits overnight.

The reality is that these overlays are a band-aid on a broken foundation. They inject a visual widget and attempt to patch accessibility issues in the browser, but they never touch the underlying source code. Screen readers and assistive technologies still encounter improperly nested headings, missing form labels, and non-semantic markup that automation cannot reliably interpret.

What screen reader and keyboard users actually need is clean, semantic HTML. That means proper heading hierarchy, accurate ARIA usage only when native semantics aren't enough, real focus management that doesn't trap users or lose their place, and full keyboard navigability without requiring a mouse. These are structural changes that happen at the code level, not in a browser-layer script.

The only real path to WCAG compliance is a manual audit performed by people who use assistive technologies every day, followed by source-code remediation. At OnlyEnable, we do exactly that: we review your site manually, identify the barriers that actual users face, and fix the code itself rather than masking the symptoms.

If you're serious about making your site truly accessible — not just legally defensible — start with the source. Learn more about how we help teams build inclusive digital experiences at OnlyEnable.
