It is in our interest that you need us less often.
That sounds awkward for an audit firm, and it is. We build these tools anyway. A site that goes well while it is being built is cheaper than an audit afterwards, and we would rather work on the hard cases than on buttons without a name.
The 28 free checks stay free, including when we add more later. There is no time limit on that.
Where the checks come from.
Across more than 900 audits we kept track of which mistakes came back, which questions we kept getting and where people got stuck once they started testing themselves. Those notes became the Radar's list of checks, split by role: an editor has different questions than a developer.
Every check links to an article on properaccess.nl explaining one success criterion in plain language, with examples from real reports. No WCAG number without an explanation next to it.

What we promise, and what we don't.
What we do
- The 28 free checks stay free, including when we add new ones
- The Radar runs in your own browser, so we never see your page
- Every check links to an article that explains the criterion
- We test this site against WCAG 2.2 AA. If you find something that isn't right, tell us
- You may ask us about a finding, licence or no licence
What we don't do
- We don't claim a tool makes your site accessible
- We don't sell an overlay widget or a button that promises accessibility
- We don't give a score you can use as proof of compliance
- We don't build websites, so we never audit our own work
- We don't send you a newsletter you didn't ask for
What we do with your data.
WCAG Radar
Runs entirely in your own browser. The page you test never leaves your computer and we can't see which sites you check. The report you save is built locally too.
The scan
We visit the address you give us and keep the result for 7 days, so you can open the report at your own link. We use your email address for that one report only.
This website
No tracking cookies, no advertising pixels. We count page views anonymously, without building profiles. The server is in Helsinki, inside the European Union.
Who is behind it.
WCAG Toolkit is built by Proper Access, an audit firm for digital accessibility in Amsterdam. We work for government, culture and e-commerce, in Dutch, English and Swedish.
We don't build websites and we don't manage content, so we never audit work we made ourselves and have no stake in a particular fix. We do sell software: WCAG Radar is ours, built on what we ran into across more than 900 audits. It runs on our own server in Helsinki, and everything around it, from storage to visitor analytics, sits with European companies.
The tools are built by Julia Tol, founder of Proper Access and senior accessibility auditor. Every check in the Radar comes from a finding that sat in a real audit report, and what we run into most often decides which checks get added next.
Stuck on a finding from the Radar or the scan? Email or call. Also when you are not a client and have no plan to buy anything.
