Free accessibility browser extensions

Automated testing

With the push of a button, axe DevTools helps you catch more than 50% of accessibility issues while coding, dramatically reducing the time and cost of manual accessibility testing down the line.

The free axe DevTools extension is lightweight and easy to incorporate into development processes and returns zero false positives. It only tests for accessibility issues that can be accurately detected via automation, and it only tests for components that actually exist on the page or application you’re testing.

Issue description library

Axe DevTools enables developers to rapidly fix accessibility issues using built-in references and solution patterns without requiring deep knowledge of accessibility standards.

When accessibility issues are found on a page, users are provided with an issue description, location, source, level of impact. They can also “highlight”, “inspect”, and learn “more info” about how to fix the problem and why it matters.
