Honest comparison
Accessibility overlays vs. real fixes for Squarespace
Overlay widgets and real source remediation are not the same thing. Here’s a fair, specific comparison, including where overlays can genuinely help, so you can decide what’s right for your Squarespace site.
To be fair to overlays: a widget can offer some visitors handy on-page controls (text resizing, contrast toggles), and that’s a real convenience for some low-vision and situational users. What an overlay does not do is correct the underlying code, so the structural problems a screen reader hits, and the issues a demand letter cites, are still there in your source.
| Overlay widget | Kat ADA: real fixes | |
|---|---|---|
| Where the change lives | A script patches the page in each visitor’s browser at runtime. Your underlying source code stays unchanged. | The fix is written into your real Squarespace content (alt text, labels, headings, contrast). It’s there in the source, with or without any script. |
| If the script is removed | The “fixes” disappear, and the page reverts to its original, inaccessible state. | Nothing to remove. The corrected content remains because it was edited at the source. |
| What screen-reader users experience | Mixed. Disabled users and accessibility experts have publicly objected that overlays can interfere with the assistive tech people already use. | The page is corrected the way a careful human editor would do it, so existing assistive tech works with it. |
| Legal track record | Sites using overlay widgets have still received ADA demand letters and lawsuits. An overlay is not a legal shield. | Also not a legal guarantee, but you get real remediation plus a dated good-faith record of the work, which is what diligence looks like. |
| Monthly human review | Typically automated only; new content can reintroduce issues with no one checking. | A specialist re-scans and fixes new issues every month and documents what changed. |
| Site performance | Adds a third-party script for every visitor to load. | No script added to your live site. Nothing extra for visitors to load. |
The honest bottom line
Neither approach makes you “lawsuit-proof,” and anyone who says otherwise isn’t being straight with you. But if your goal is to actually improve accessibility for real users and to hold a dated record of a good-faith effort, real source fixes are the stronger answer, and on Squarespace, that’s exactly what we do for you.
