axe DevTools - Web Accessibility Testing Extension

Find and fix more accessibility issues during website development with axe DevTools.

The free axe DevTools browser extension is a fast, lightweight, yet powerful testing tool driven by the world’s most trusted accessibility testing engine, axe-core, developed by Deque.

Why use axe DevTools to build accessible websites?
-To deliver brilliant user experiences for everyone, including the 1 billion people globally living with a disability today.
-To avoid wasting time chasing fake issues. Only axe prevents false positive results.
-To improve accuracy, preventing tickets from resurfacing again and again.
-To reduce the risk and cost of accessibility lawsuits.

★ Automated testing
With the push of a button, axe DevTools analyzes your site, automatically surfacing the majority of common accessibility issues—almost triple the industry average. Drill down into each issue, inspect the source of the problem and leverage extensive free remediation guidance to fix it quickly and accurately.

★ No False Positives
Nobody has time to chase issues that aren’t actually issues. Axe DevTools reports only issues with absolute certainty. Other tools report irrelevant and inaccurate results, wasting your time, money, and productivity on rework.

★ The fastest and most effective path to accessible
Using axe DevTools to proactively find and fix accessibility issues significantly reduces the need for manual testing, giving you quick and easy wins without disrupting your development velocity.

Upgrade to axe DevTools Pro to do so much more:

★ Intelligent Guided Testing™ (IGT)
Perform more advanced testing without having to become an accessibility expert. Using a simple question and answer format, IGT leverages machine learning to help you quickly find and fix issues that are not detectable by automated testing alone. Adding IGT can get you 8o% coverage or more—while you code.

★ Component-level testing
Make your testing more agile by focusing only on the specific parts of a page relevant to your immediate work. Reduce patching and retesting by finding accessibility bugs that could break existing use cases.

★ Export, Save and Share
Collaborate across your dev team! With one click, create a customized URL with all issue description information to share with colleagues or your issue tracking software of choice. Save the rest of your team time and effort and help them build inclusive experiences.

★ What’s left to test?
After you’ve finished automated and Intelligent Guided Tests, now you can generate and share a “Remaining Testing” report, listing what’s left for manual testers. Accessibility experts can pick up exactly where you left off to catch the remaining complex issues.

Paul G (ID: 000000ed62836f6e) Voted 5 ★ - Updated 10/13/2023 A valuable resource in checking web accessibility. Hopefully even more clever tricks can be included to automate accessibility checking.

icon

Anthony Cunningham (ID: 0000007e3f729575) Voted 1 ★ - Updated 05/11/2023 Constantly badgers the user to upgrade to the paid version. Not worth the aggravation.

icon

James Reetzke (ID: 000000afa9eaba98) Voted 2 ★ - Updated 04/13/2023 Doesn't seem to do much without purchasing the "pro" version. Not sure why this is so highly rated.

icon

Dave Gallant (ID: 00000021d940ee90) Voted 1 ★ - Updated 03/15/2023 This was a great extension to use, they have since changed it to just push the paid version. If you are not looking to pay for the extension the free version offers nothing.

icon

Z Z (ID: 00000014652788e4) Voted 1 ★ - Updated 03/04/2023 This tool used to be great, now it's it's a scam. Doesn't actually scan anything. Instead, wants you to subscribe to a 7-day trial and collect your personal information or subscribe to their pro version to unlock anything remotely useful. "Accessibility is for everyone," right?
