WAVE is a web accessibility evaluation tool developed by WebAIM.org. It provides visual feedback about the accessibility of your web content by injecting icons and indicators into your page. No automated tool can tell you if your page is accessible, but WAVE facilitates human evaluation and educates about accessibility issues. All analysis is done entirely within the Chrome browser allowing secure valuation of intranet, local, password protected, and other sensitive web pages.
To run a WAVE report, simply click on the WAVE icon to the right of your browser address bar, or select "WAVE this page" from the context menu.
WAVE errors align with WCAG 2.2 failures. The WAVE interface facilitates human evaluation of many other aspects of accessibility and Web Content Accessibility Guidelines, ADA, and Section 508 compliance.
Version 3.3.0.4 (December 2025) - Bug fix for scripting exception with some pages with small text. Minor interface improvements.
Version 3.3.0.3 (November 2025) provides performance, interface, and testing improvements. Improved support for ARIA headings and prefers-reduced-motion user settings.
Version 3.3.0.0 (October 2025) adds numerous new features, enhancements, and bug fixes. Resetting the extension no longer refreshes the page, thus supporting better testing of dynamic content. The Summary and Details panel are now combined. The AIM Score is presented. Viewing the Order, Structure, or Contrast tabs now filters to only relevant page icons. The WAVE sidebar can now be collapsed out of view.

Not a good tool. The UI is poor and confusing. The results can sometimes overlay the page content makin impossible to find the problem. It does not refresh/reassess the page when you navigate thru the websites.
It's great but it misses a very important feature: The ability to simply rerun the accessiblity check without having to reload the full web app. It becomes very cumbersome to test all combinations of your app state when you have to reload the web app every time you want to rerun a test.. It would be nice if the sidebar simply had a "RECHECK" button.
According to https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum.html , an inactive button has no contrast requirement, but the tool shows a Very Low Contrast error in an inactive button in my Web site. This appears to be an error in this Chrome extension.
This is great, I found it when I was blocked from their website due to limits, I didn't know this existed Its much faster than using their website. The only issue I have, which would gain it 5 stars if this was addressed, is when you navigate to a new page or refresh the page the tool is not enabled again, you have to click the plugin icon every time, so it can be annoying. Ideally it should have an enable permanent feature so it will stay active and check pages as you navigate a site or refresh pages. That would be ideal. Thanks
Room for improvement. Very annoying that every page that gets validated you have to deselect all of the valid aspects. When this is turned off it should remain off. -- We need to know what to fix, not what's already good.
This app has recently been updated and I have to say that it has brought massive improvements in the UX and performance of the tool. It's much more impressive than it was a year or so ago, and it has a lot more features packed in. It's important to note that genuine accessibility is not just a checkbox- making your site useful without javascript is not a trivial task, and really has to be done with a human touch. However this tool is an excellent first step in pointing out the basics. Developers note, sometimes things like debug overlays (like django/flask ones) can get warnings flagged and hidden which makes them sometimes hard to find- but there's nothing this tool can do about that- it's inspecting the entire window.
Recently I have used many different accessibility checkers, all are useful but many are not efficient to use. Wave shows me clearly what the issues are, shows me markers visually on my own page and provides a clear description of the issue and what to do about it.
As a fullstack developer, this is the first time that the topic "Accessibility and UIs (React/Spa)" comes into contact. A cover of Specs is to be considered, this Tool makes the entrance into this not quite simple topic for me clearly easier. My thanks go to the developers, very useful.
Where did the ability to filter down to WCAG AA 2.0 go? What standard is the new redesign using as the "default"?
The new update is really useful. It breaks the page layout less than the old version, explains what's wrong - WHY it's important and how to fix it. Thank you.
