CoreA11y / Products / Overlay alternative
An accessibility overlay alternative that fixes the code
Accessibility widgets add a toolbar on top of your site. CoreA11y finds the problems in your pages, fixes the ones that are safe to fix, and shows you how to fix the rest. No widget, no toolbar, and every fix can be undone.
- No overlay or toolbar
- Undo for every fix
- Free plan
01 / Why switch
Why people look for an overlay alternative
Overlay tools such as accessiBe, UserWay, AudioEye and EqualWeb are built around a script that loads on top of your website. Most show a floating icon that opens options like bigger text or high contrast, and many say the script repairs problems as each page loads.
The trouble is that your site's code stays the same. Screen readers, keyboards and auditors read that code, so the problems are still there for the people who need them fixed. Many people who use assistive technology already have their own settings, and a second set of controls on top can get in the way.
About 1,400 lawsuits
In 2025, roughly 1,400 US accessibility lawsuits named sites that already had a widget installed. Source: UsableNet.
A $1 million FTC order
In 2025, the US Federal Trade Commission ordered a leading overlay vendor to pay $1 million over claims that its tool could make any website WCAG compliant.

Overlay vs CoreA11y
| Feature | Accessibility overlay | CoreA11y |
|---|---|---|
| What it changes | A copy of the page in each visitor's browser | The code your visitors receive |
| What visitors see | A widget or toolbar | Your normal site, working better |
| Problems it can't fix | Often not shown to you | Listed, with plain-language steps to fix them |
| Undo | Turn the whole widget off | Undo any single fix |
| Proof of the work | Usually a badge or certificate | Before-and-after reports you can share |
| Alt text | Often written by AI | Written by you, from one list of every image |
| What it promises | Often "compliance" | An honest report. No tool can guarantee compliance |
02 / How it works
How CoreA11y works instead
Audit
Check your pages against WCAG 2.2 AA at desktop and phone width. Every problem comes with what it is, who it affects and where to fix it.
Fix
Turn on quick fixes for common problems, such as skip links, focus outlines, form labels and button names. Each fix changes your site's code, not a visitor's screen.
Undo
Every fix has an undo. Turn one off and it's gone from every page.
Prove it
Re-run the audit and share a before-and-after report with your team, your clients or your lawyer.

Questions
Is CoreA11y an overlay?
No. There's no widget or toolbar for visitors. CoreA11y changes your site's code, and you can undo any change.
Will CoreA11y make my site compliant?
No tool can promise that, and we won't. CoreA11y checks your site against WCAG 2.2 AA, fixes common problems and shows you what's left. Some checks, like whether alt text describes an image well, need a person. We include guided manual checks for those.
Can I keep my widget while I switch?
Yes. Run your first audit with it on, fix what you can, then remove it. Some widgets change the page in ways that can hide real problems, so your final audit is more accurate without it.
What about audits and services from overlay vendors?
Some overlay vendors, such as AudioEye and accessiBe, also offer audits or services. This page compares the widget approach. If you use a vendor's audit, ask whether the fixes change your source code and whether you can see and undo them.
Is CoreA11y free?
There's a free plan on WordPress, Wix and Squarespace. Pro adds more quick fixes and reports. See Pricing.
