axe DevTools - Web Accessibility Testing
Accessibility Checker for Developers, Testers, and Designers in Chrome
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.

Could someone help with the error below, got it when trying to Full Page Scan. Error: BackgroundRecorder is not running in a known context at #t (chrome-extension://lhdoppojpmngadmnindnejefpokejbdd/content.bundle.js:2:85128) at async t.advancedRun (chrome-extension://lhdoppojpmngadmnindnejefpokejbdd/content.bundle.js:2:90883) at async chrome-extension://lhdoppojpmngadmnindnejefpokejbdd/content.bundle.js:2:51920
Somehow it breaks the rendering of the openapi specification in Gitlab.
The tool stopped working, almost no errors are shown when other tools show basic code errors are present. Not sure if this was because of an update or what happened.
As a QA department, the EAA has really pushed the importance of proper Accessibility analysis which conforms with the WCAG 2.1 AA guidelines. This tool is a tremendous help in analyzing the quality of our product from an Accessibility perspective, and provides a wealth of information concerning the issues it has observed. This doesn't just allow us to put the bulk of the time into the more functional aspects of accessibility implementation, it also allows us to direct our developers in the right direction based on the information it provides. Sure, it's not super pretty. But I'll take its functionality and immense information provisioning over some slick UI any time of the day. In addition, I advise to take the licensed version if you want to use it in a professional setup. It's cheap for what it does, and the licensed version adds some additional functionalities that make this tool even more reliable.
This free extension does a great job in identifying accessibility issues that can be checked in an automated fashion. Each error is provided with references to the code and tips on how to address the problem as well as links to WCAG information. I was using the free version since 2018. If you pay for their Pro version of the tool (which I have since 2023), additional helpful features are available. You can save a page's test results on the web and share it with collaborators who are involved with fixing the problems. You can also export the list of issues to an external file if desired. A nice feature of the pro version is their Guided Tests addition. These tests are beneficial for those who don't know a lot about accessibility manual testing and they help guide you in identifying other problems related specifically with respect to tables, forms, keyboard navigation, and more. I've tried other extensions which don't compare in the way feedback is presented. And those other tools don't seem to identify as many issues as DevTools identifies.
Looks like it would be useful, but the free version doesn't currently let you select WCAG 2.2AA, which is the standard being expected by the UK GDS for Public Sector websites since October 2024. https://www.gov.uk/guidance/accessibility-requirements-for-public-sector-websites-and-apps#meeting-accessibility-requirements
Just hope it can support WCAG 2.2 sooner! Very handy tool to use.
Great extensions, help us identify and fix accessibility issues
must be broke or something it doesn't do anything
Great extension! But Enabling this breaks the openapi preview mode, throwing the error "Please indicate a valid Swagger or OpenAPI version field". Disabling the extension makes it work. I love this extension but 1 star just to get the attention as this makes it cumbersome to look with the api contracts written in openapi. I'll surely update the review once it's fixed.
Great Tool . Need clarification whether is it able to identify colour contrast issues and did we have screen reader in this tool?
This is a wonderful free disability compliance check on your web page. Thank you!
This ha been an excellent feature. Please confirm if the extension to cover WCAG 2.2 has been made open to all?
Thanks. Could you please confirm if this is latest version of Axe ? I believe this covers up to WCAG 2.1 AA standard issues.
Hello, I have to say this is a very useful tool. It quickly runs in the browser, scan my pages and triggers very helpful results about the issues found it and point the exactly parts of my code with the issue. Is there any plan to update soon the webtool to covers WCAG 2.2 AAA?
Doesn't work if you are not pay lol
Good tool, but only if you pay for it. Elementary basic functions were once free, but now have to be paid for. It's worth it if you use it regularly, but it's no longer useful for occasional users.
is there any feature regarding speech reading in axe developer tool plugin? Sorrt to give 3 star , I have used the product from a month , found it user friendly and one of the best app in finding accessibility issues. My rating has been changed now.
This extension uses amplitude for tracking, which gradually fills your cookie with junk 'amp_cookie_text<randomstring>' causing sites to fail to load. Privacy nightmare and shady practices
Axe Devtools Pro is truly fantastic. It's user-friendly and easy to comprehend. When compared to other accessibility products, it stands out as the best.
Tried to run a test, but it's purely focused on getting you to upgrade. Useless by itself, don't waste your time.
A valuable resource in checking web accessibility. Hopefully even more clever tricks can be included to automate accessibility checking.

Quick and easy to use. Very trustworthy results.
Constantly badgers the user to upgrade to the paid version. Not worth the aggravation.

Doesn't seem to do much without purchasing the "pro" version. Not sure why this is so highly rated.

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.

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?

it didn't give me anything other than attempts to upsell to Pro version right away

Works great! However axe DevTools does not use the latest axe-core ver. It uses 4.4.2 when the latest available ver is 4.6.1. Are there any plans to update to the latest ver?

Tried a test. Immediately popped up a notification to upgrade to a pro-version.

Good extension, but seems to recently have switched to a paid subscription after an initial trial, and the free version of the extension only displays 50% of the accessibility issues discovered (which is a bit pointless if you're wanting to perform a worthwhile audit).

You can't change to WCAG 2.1 AA and it tests against AAA which is not what you always need. You should have flexibility to test against any WCAG level. Also you should be able to export the results using this extension. They scare you for no reason. You mostly need AA compliance and not AAA
