How do I check if my website is ADA compliant?

Paste your URL into the checker above and run a scan at WCAG 2.1 AA, the level the ADA Title II rule names. The report lists every failing element with its WCAG criterion and severity. Because automated scans catch only part of the issues, follow up with keyboard and screen reader testing before you call a page compliant.

How do I check my website for WCAG compliance?

Run a scan, pick the WCAG version and level you are held to (2.0, 2.1, or 2.2 at A, AA, or AAA), and review the failures grouped by success criterion. Each issue links to the WCAG reference and includes remediation guidance with a code example.

Which WCAG version should I test against?

Most teams target WCAG 2.2 Level AA, the current version. If a regulation names an older version, such as WCAG 2.0 AA for Section 508 or WCAG 2.1 AA for the ADA Title II rule and EN 301 549, scan at that level as well so your reports match what an auditor will check.

Can an automated accessibility checker find every issue?

No. Automated scans reliably catch roughly 30-40% of accessibility issues, such as missing alt text, low color contrast, unlabeled form fields, and invalid ARIA. Keyboard traps, confusing focus order, and screen reader announcements need manual testing, which TestMu AI supports with the Accessibility DevTools keyboard scan and screen reader sessions.

Does a clean scan mean my site is compliant?

A clean scan means no automated rule failed at the level you tested. It is strong evidence, and you can export it as a PDF or CSV report, but compliance also depends on the issues only manual and assistive technology testing can find.

Can I scan my whole website?

Yes. A multi-page scan checks up to 1,000 URLs at once, added by hand, from a CSV file, from your sitemap, or by crawling from a starting URL. Accessibility scheduling re-runs those scans daily, weekly, or monthly and picks up new sitemap pages automatically.

Can I check pages behind a login?

Yes. The Chrome extension scans any page you can open in your browser, and scheduled scans can sign in with saved credentials before they check authenticated pages.

What do Critical, Serious, Moderate, and Minor mean?

They rank how badly an issue blocks users. Critical and Serious issues stop people from completing a task, such as a form they cannot submit with a keyboard, so fix those first. Moderate and Minor issues make a page harder to use without blocking it.

Is there a Chrome extension for accessibility checks?

Yes. Accessibility DevTools runs the same WCAG checks from inside Chrome, marks each failing element on the page, and adds partial, multi-page, workflow, and keyboard scans.

What happens after I start a scan?

You sign in or create a TestMu AI account, and the scan of your URL starts from there. Results land in the accessibility dashboard, where you can filter by severity or WCAG criterion, export the report, and add the same checks to your automated test runs.

What Is an Accessibility Checker?

An accessibility checker is a tool that scans a web page against the Web Content Accessibility Guidelines (WCAG) and reports the elements that fail, such as images without alt text, text with too little color contrast, and form fields without labels. The TestMu AI accessibility checker runs on axe-core and tests against WCAG 2.0, 2.1, and 2.2 at levels A, AA, and AAA.

Each result names the failing element, the WCAG success criterion it breaks, a severity from Critical to Minor, and how to fix it. Because the ADA, Section 508, and the European Accessibility Act all point back to WCAG, one scan covers the checks each of them relies on.

How the Accessibility Checker Finds and Fixes Issues

Scan a page, rank what failed, fix each issue with guidance, and extend the same checks to your whole site.

Automated Checker vs Manual Audit
