Free website accessibility checker

Paste a URL and we load the page in a real browser and run automated WCAG 2.1 AA checks — colour contrast, image alt text, form labels, ARIA, headings and more. You see the severity breakdown and the top issues, with the exact element to fix.

One page per check · Automated WCAG 2.1 AA rules · Usually takes 1–2 minutes

What the free check covers

The same automated rule engine that powers the full QA Proof accessibility audit, run on one page.

Images and alt text

Images, SVGs and image links without a text alternative screen readers can announce.

Forms and labels

Inputs without an accessible label, placeholder-only fields and duplicate labels.

ARIA and names

Invalid roles and attributes, and buttons or links with no accessible name.

Structure and navigation

Heading order, landmarks, skip links, page language and duplicate IDs.

Keyboard and focus

Suppressed focus indicators and interactive elements that are too small to hit.

An honest note on automated testing

No automated tool can certify that a website is accessible or legally compliant — including this one. Automated rules reliably catch many common, measurable problems such as contrast, missing labels and invalid ARIA. Other WCAG criteria, like whether alt text is actually meaningful or whether a flow works with a screen reader, need a human to review. Use this check as a fast first pass, not as a certificate.

Common questions

Yes. You can check a page without creating an account. To keep the tool available for everyone there is a limit of a few checks per hour per visitor, and a page that was checked recently shows its recent result.
Automated rules for WCAG 2.1 Level AA, which is the level most accessibility laws and procurement rules refer to. A few findings, such as small touch targets, come from WCAG 2.2 and are reported as low severity.
No. This is an automated check of a single page. It finds many common issues, but compliance also depends on criteria that need manual review and on every page and user flow of your site. Treat the result as a starting point.
The free check shows the severity breakdown and the three most important issues. Create a free account to run the full audit and see every issue with fix guidance, screenshot markers and a PDF report.
Any publicly reachable web page. Pages behind a login, private network addresses and sites that block automated browsers can’t be checked.
We keep the page URL and the summary result for up to 30 days so repeated checks of the same page are instant. We don’t need your name or email to run a check.
