Website accessibility checker

An automated accessibility checker finds common WCAG 2.2 failures in seconds, such as missing alt text, unlabeled form fields and blocked zoom. Enter a page address below for a free scored report. Automated checks catch only part of the issues, so compliance needs a manual audit.

Public pages only. We fetch the HTML once, check it and do not store the page.

What the checker tests

It reads the HTML your server sends and runs the WCAG 2.2 checks that can be done reliably on markup alone. Content added later by JavaScript is not seen, so single-page apps may show fewer elements than a visitor would.

What it cannot tell you

No automated tool can judge whether alt text is accurate, whether the focus order makes sense, whether color contrast holds up on images, whether videos have correct captions, or whether a form's error messages help. Those need manual testing with a keyboard and a screen reader. That is why the score is a starting point and not a compliance certificate.

Accessibility laws in the US and Canada

United States: the ADA. Title III of the Americans with Disabilities Act covers businesses open to the public, and the Department of Justice has said this includes their websites. The Title III rules do not name a technical standard, so settlements and courts usually point to WCAG Level AA. For state and local governments, the 2024 Title II rule adopts WCAG 2.1 Level AA.

Ontario: the AODA. Under the Integrated Accessibility Standards Regulation, designated public sector organizations and businesses or nonprofits with 50 or more employees in Ontario must make their public websites meet WCAG 2.0 Level AA, with exceptions for live captions and pre-recorded audio descriptions.

Federal Canada: the Accessible Canada Act. It applies to the federal government and federally regulated organizations such as banks, telecom companies and airlines. It requires accessibility plans, feedback processes and progress reports, and the digital benchmark is CAN/ASC-EN 301 549. Read our Accessible Canada Act guide and EN 301 549 explainer.

This is general information, not legal advice. Which rules apply depends on your organization and where you operate, so check with a lawyer.

Getting issues fixed

Most failures this tool finds are quick to fix in a theme or template. We build new sites to WCAG 2.2 AA and remediate existing ones. Read the web accessibility guide, see our services, or ask for a quote below.

FAQ

Frequently asked questions

No. Automated checks catch only part of WCAG issues, and the ADA does not offer a certificate. A scan is a fast way to find common failures; a manual audit with keyboard and screen reader testing is needed before you can say a site conforms to WCAG.

It checks the page HTML for missing language, title and alt text, unnamed links and buttons, unlabeled form fields, heading structure, blocked zoom, duplicate ids, skip links, autoplaying media, positive tabindex, untitled frames, vague link text, the main landmark and timed refreshes.

The Web Content Accessibility Guidelines 2.2 are the W3C standard for accessible web content, published in October 2023. Version 2.2 added nine success criteria, such as minimum target size and focus not being hidden, and retired 4.1.1 Parsing. Level AA is the usual target.

In the US, the ADA covers businesses open to the public. In Ontario, the AODA requires WCAG 2.0 AA for public sector organizations and organizations with 50 or more employees. Federally regulated organizations in Canada fall under the Accessible Canada Act. This is general information, not legal advice.

The page may block automated requests, take longer than 8 seconds, be larger than 2 MB, sit behind a login, or build its content with JavaScript after loading. The checker only reads the HTML the server sends and only scans public addresses.

No. The page is fetched once and discarded after the checks run. The report is kept in memory for up to two hours so you can email it to yourself. If you request the email, we keep your contact details and the report summary to follow up.
