Free ADA compliance checker
Enter your website to check a page against the WCAG 2.2 A and AA rules a computer can test. It's free, it usually takes under 30 seconds, and you don't need to sign up. No tool can tell you a site is ADA compliant, including this one. What it does is show you what to fix first.
What does the checker look at?
It opens your page in a real browser and runs axe-core, the open-source accessibility engine made by Deque Systems, against the WCAG 2.2 Level A and AA rules that can be tested automatically. WCAG is the yardstick ADA website demand letters and lawsuits use.
- Every problem in plain English: who it affects (for example, people using screen readers) and how to fix it.
- Steps for your platform: click-by-click fixes for Shopify, WordPress, Wix and Squarespace.
- Accessibility widgets: it flags overlay widgets like accessiBe, UserWay, AudioEye and EqualWeb, which don't fix the page underneath.
- Your accessibility statement: whether the page links to one.
- A privacy check: ad pixels, session recorders and chat widgets that start before a visitor agrees to tracking.
- Proof: save the results as a dated PDF or share a link to them.
What can't a free checker tell you?
More than most tools admit. Deque, the company behind axe-core, found that automated tests caught about 57% of accessibility issues on average in its own audit data (Deque, 2021). The rest need a person.
- It checks one page at a time. Scan your homepage, then the pages where people buy, book or contact you.
- It can't fully test a keyboard or a screen reader. Try using your own checkout with only the Tab and Enter keys.
- A clean result isn't a certificate. It means no problems a computer can detect on that page, at that moment.
What are other free checkers?
Use more than one if you like. They run similar tests and they're all free:
- WAVE by WebAIM marks problems directly on your page.
- axe DevTools is a browser extension that runs the same engine we use. It also works when a site's firewall blocks outside scanners.
- Lighthouse is built into Chrome and includes an accessibility score.
What Due Effort adds is the plain-English fix for your platform, the widget and privacy checks, and a dated record you can keep.
Already got an ADA demand letter?
Don't ignore it and don't pay in a panic. Read what to do in the first 72 hours. If your lawyer needs the facts fast, the Letter Response Kit scans up to 25 pages and seals the results into a dated evidence pack. If you've been served with court papers, talk to a lawyer today.
Questions people ask
Is it really free?
Yes. You see every result without signing up or giving an email address.
Does a clean scan mean my website is ADA compliant?
No. Automated checks find only some problems, so no scan can confirm a site is compliant. A clean result is a good sign, and a dated record of it is worth keeping.
Will the checker fix my website?
No. It shows you what's wrong and how to fix it. The fixes happen in your theme or page builder; our fix guides walk through each platform.
Why did my scan fail?
The site may be down, slow, or blocking automated browsers with a firewall such as Cloudflare. The free axe DevTools browser extension runs from your own browser instead.
Due Effort is not a law firm and this page is not legal advice. Automated scans find only some accessibility problems, so a clean scan doesn't mean a site is compliant.
