Plain-English guide
That accessibility “overlay” widget, honestly
An overlay is a little widget you drop into your site that promises to make it accessible — sometimes even “legally compliant” — without touching your code. One script tag and a monthly fee. Before you buy one, or renew one, here's what regulators, lawsuit data and specialists have actually put on the record.
The biggest overlay maker paid a $1 million settlement
On the recordIn April 2025 the U.S. FTC finalised a $1 million settlement with overlay vendor accessiBe. It covered claims that the widget could make websites automatically meet WCAG 2.1 AA — plus reviews formatted to look independent when they weren't. A regulator sanctioned the exact promise the whole category sells.
A quarter of sued sites already had a widget installed
Not a shieldUsableNet's 2025 count found that 983 of 3,948 sites hit with digital accessibility lawsuits were already running an overlay when they were sued — that's 24.9%. Whatever an overlay does, the data doesn't back up “protects you from legal action.”
The people who do this work advise against them
1,031 specialistsThe Overlay Fact Sheet — an open letter from the accessibility field — carries 1,031 signatures advising against overlays. In WebAIM's survey of practitioners, 67% rated overlay products not effective; among people with disabilities, the folks overlays claim to help, that rises to 72%.
Even overlay vendors put automation at about half
By their own countAudioEye — itself an overlay vendor — acknowledges automation handles roughly 50% of accessibility issues, and sells expert services on top. Keep that number in mind any time a widget is marketed as complete compliance.
Our scanner is automated too — here's the difference
Honest scopeAutomatic scanning, ours included, covers about 57% of issues by volume (Deque, 2021), and we don't claim otherwise — and we don't inject anything into your site. The difference is what happens next: an overlay leaves your code broken and layers a widget on top; we find the real problems in your markup and fix the code, or hand your web person a clear list. Fixed code works for everyone — no script tag, no renewal.
Already paying for one? Don't panic
What to doDon't rip it out in a hurry. Scan your site first — with the overlay still running — and look at what's failing underneath. That gap is the difference between what you were sold and what you actually have. Then decide where that monthly fee should really go.
