What is an online accessibility checker?

An online accessibility checker evaluates a web page against accessibility standards like WCAG directly in your browser, flagging issues such as missing alt text, low color contrast, and invalid ARIA. TestMu AI's checker is the axe-core-powered Accessibility DevTools Chrome extension, so you can check any live page and report issues without installing heavy software or wiring up a framework.

How do I check a website for accessibility?

Add the Accessibility DevTools extension to Chrome, open the page you want to check, and run a scan. The checker evaluates the page against WCAG using axe-core, groups the results by issue, and lets you export a report so you can prioritize and fix what matters.

What types of scans can the accessibility checker run?

The checker supports four scan types: Full Page to check an entire page, Partial Page to target a specific element or section, Multi-Page to check several URLs at once for site-wide consistency, and Workflow to capture dynamic interactions and page changes across a user journey.

Is the online accessibility checker free to use?

You can add the Accessibility DevTools extension to Chrome and start checking pages right away. Sign in with your TestMu AI account to save results, use the centralized dashboard for ongoing health monitoring, and share reports across your team.

Does the accessibility checker use axe-core?

Yes. Checks are powered by axe-core, a widely used accessibility rules engine, so results align with recognized WCAG checks. (Axe-core® is a trademark of Deque Systems, Inc. in the US and other countries.)
