Evaluate web accessibility within your browser.
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 2.1 failures. The WAVE interface facilitates human evaluation of many other aspects of accessibility and Web Content Accessibility Guidelines and Section 508 compliance. Version 3.1.6 (October 2021) includes numerous bug fixes and test rule enhancements for better testing contrast (filters, background images, and other complex color definitions are better handled), document language (IANA-defined language values are now tested), empty links and buttons (better ARIA support for accessible name computations), broken ARIA references, etc., etc. Performance and accessibility has been improved. Version 3.1.3 (November 2020) includes performance enhancements and fixes several minor bugs, including fixes for multiple alerts for some pseudo-lists and disabled controls being incorrectly flagged for contrast failures. Version 3.1.2 (October 2020) fixes several minor bugs, including with the Structure tab sometimes incorrectly showing no structure, and improves performance and accessibility testing reliability. Version 3.1 (September 2020) includes new accessibility tests (region, figure, possible list, select element missing label, and image with title), improved contrast checking, expanded lang attribute value checking, and numerous other bug fixes and improvements. Version 3.0.9 (July 2020) includes numerous bug fixes, improved accessibility, and improved color contrast checking including fewer false positives and expanded contrast checking for form inputs.
- (2022-08-03) Ermes Mox: Slow, old, with a lot of issues. It's time to update and improve this tool.
- (2022-05-25) Mitchell Christensen: Great tool. Thank you for providing such a useful tool for accessibility
- (2022-05-21) Rocky Kev: Used this to update and ensure accessibility for hundreds of sites.
- (2022-02-09) Kim Tan: Can't seem to get it to work on the latest version of chrome :(
- (2022-02-02) Ferran Buireu: Fácil de usar y con reportes detallados.
- (2021-12-20) A D: This used to work for local html files. It no longer does? Edit: You need to enable file access in the extension settings. This is an extremely helpful tool.
- (2021-11-23) James Kuffner: The wave results sits over part of the web page being assessed and therefore any errors on the page are hidden by the results. Desaturate page resizes the page to fit next to the wave results which is great and the normal view should do the same.
- (2021-11-05) Ryan: Useful tool, and at an unbeatable price point of 'free'. But there's no way to output errors - even a raw txt file with error type and the line of code would be fine, not looking for anything fancy. UI is tucked off to one side, so once you have more than a handful of errors it's very easy to get lost in a sea of repetitive and small error indicators. Crashes Chrome not infrequently when making use of the Code view with styles turned on.
- (2021-10-25) Marcelo Quintino da Silva: 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.
- (2021-08-02) Freddy Jey: 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.
- (2020-10-27) Dario Alpern: 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.
- (2020-10-12) Laurence Cope: 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
- (2020-08-03) Adam Reece: 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.

- (2019-12-10) Darren Sweet: 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.
- (2019-11-28) Remi Dijoux: bof
- (2019-11-22) Andreas Schieferbein: 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.
- (2019-11-04) Andy Layman: Where did the ability to filter down to WCAG AA 2.0 go? What standard is the new redesign using as the "default"?
- (2019-11-01) Daryl Knight: 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.
- (2019-10-30) Alex O'Connell: Something JUST broke the extension, we use it daily at work here, and today I went to use it and its now broken
- (2019-10-30) Joshua Rogers: The update looks so much nicer, good job! I ran into an issue where I needed to test locally and couldn't use my normal tools, and after finding this Wave plugin I don't need to any more!
- (2019-10-23) Luke Pennings: Clunky; and nearly always points out non-issues with very little direction on where they are originating. You would only use this if you are a QA person for basic HTML and you need to get by not knowing any code at all.
- (2019-09-25) Colleen LeMasters: This proved to be a very handy tool for assessing web accessibility but I wish I knew to what standard it was being measured... WCAG 2.0? A? AA? If that was added, it would be extremely helpful. Bonus points if we could select the level at which we tested.
- (2019-09-20) Felina: Is WAVE up to date with WCAG 2.1?
- (2019-08-22) Dan Paguirigan: A lot of false positives.
- (2019-05-10) Austin Powell: It is a powerful and useful tool for sure. It takes a little time to figure out the interface and be able to determine what it is telling you. It also slows down the browser quite a bit when it is in use. But again, it is very in depth and beneficial when testing a11y. Give it a try and see if it's abundant information is worth the learning curve and performance slowdown.
- (2019-04-30) Jay Fortner: Gives a report but you can't do anything with the report items. You can click on stuff and maybe it'll take you to the element it's referencing but most likely not.
- (2019-04-02) M KSHR: 幾つかの「アクセシビリティ・チェックツール」を試しましたが、最も分かりやすくエラーを表示してくれます。（テストするページの画面にエラーやその他のアイコンが表示される。そのアイコンを押すと問題箇所のHTMLが表示される。視覚的に理解しやすい） ローカル環境でテストできる（テスト環境でテストできる） HTMLの書き方をもっとシビアにチェックしてくれるともっと使いやすくなる。
- (2019-03-26) julio cesar martinez zarate: Excelente... Gracias
- (2019-01-12) Víctor Sagal: Excelente para evaluar accesibilidad web en línea con el cumplimiento de las pautas WCAG de la W3C, también se puede usar su versión web para el mismo cometido.
- (2018-10-22) Amanda Calvert: This is a great tool. My only suggestion is that you give us a way to download the results. I use this tool for sites that take human interaction to navigate the site where I can't use my automated tool. I would love to be able to download the results to send to my IT team.
- (2018-10-16) Patricia Acosta: Excelente herramienta
- (2018-05-12) Kishan Kock: Confusing user interface, and shows some webpages as nothing more than raw HTML when trying to evaluate, even if the page follows W3 spec immaculately.
- (2018-02-28) Andreas Poloczek: Diese Erweiterung gehört zum Standardwerkzeug eines jeden Webdevelopers oder Webdesigners. Prüft und visualisiert technische Umsetzungsfehler in Bezug auf barrierefreie Webseitengestaltung und sensibilisiert auch den in die Jahre gekommen Routineabarbeiter…
- (2018-02-22) Angel L: Continues to work great when your site was not planned with accessibility in mind. The contrast errors are sometimes off when trying to edit in the tool, but not wrong. Tried aXe extension and it broke this tool. Stay away from aXe. Stick with Wave!!!
- (2018-02-09) Magnus W: It would be great if it could display the webpage as it would actually by understood by a screen reader, for example removing all elements with aria-hidden="true". I can only get it to mark them, but that's not quite the same.
- (2018-01-31) Arturo Estrada: Very helpful for checking AA compliance
- (2017-12-06) DP Bhatt: Awesome tool.
- (2017-11-10) Ashwin Mekala: awesome tool! used for our company website.
- (2017-07-03) Keitel Jovin: I really like this one the first minute I use it. I'm improving my website SEO after I evaluate it from online evaluators. But the problem is I wanted to evaluate the progress I'm making at Development environment. So this tool is perfect for that. I would give 5/5 +1 (bonus)!
- (2017-03-23) Jennifer Little: I find this tool amazing for quickly accessing the quality and accessibility of my websites. It's easy to make sure inputs are correctly labelled, images have alt text, and headings are ordered logically. Good HTML structure benefits everyone!
- (2022-07-27, v:3.1.6) Lovro Hrust: It does not work on chrome developer version 105.0.5191.0
Uncaught TypeError: wave.fn.initialize is not a function at Object.init (wave.min.js:1:92943) at HTMLDocument.<anonymous> (wave.min.js:1:93105) at k.fn.init.ready ((indeks):3:7051) at new k.fn.init (wave.min.js:1:25824) at k (wave.min.js:1:1104) at wave.min.js:1:93087 All other extensions are disabled.

Once used, if you refresh the page the icon stays blue and can't reuse it without disabling it and enabling it again.
- (2022-02-22, v:3.1.6) Mark McGuire: Add option to remove WAVE from Google Chrome "right click" menu
Make it easier for your users to choose a less cluttered right-click menu in Chrome.
- (2022-02-16, v:3.1.6) Michael Heilig: Export
Is there anyway to export the results from running wave on a particular website?
- (2022-01-13, v:3.1.6) HG Digital Marketing: Cloudflare Whitelist IPs for WAVE Accessibility
Hello, our website provider has enabled Cloudfare, and since then, we were not able to check the website with Wave. They might be able to whitelist your IP address if you can provide us your IP address. IP addresses must be static, not dynamic (we cannot whitelist dynamic IP addresses). Please let us know if it's possible. Mane Manukyan
- (2021-11-17, v:3.1.6) Andrea Van Benschoten: Using the Chrome extension
The Chrome extension certainly has a lot available to review! One question however, when I turn on the extension to review a page, the page does not refresh and move over when the WAVE panel opens. The panel is positioned on top of the site. I've tried this on several different sites and seem to experience the same issue no matter what I do. Is there anything I am missing? Thank you.
- (2021-10-06, v:3.1.3) Agam Bhatia: Different outputs for 3.1.4 and 3.1.3
The extension has different versions on Edge and Chrome and is giving different results across these browsers. Is there an update coming to the chrome version as well?
- (2021-07-26, v:3.1.3) Merlijn Ackerstaff: persistent settings
I love this extension and it is really really helpful, but I do have a question; Is there a way to keep the panel open and keep settings across page reload / site navigation? I find it very very annoying to have to re-do all settings every time I reload the page or navigate to a different one. Thank you!
- (2021-07-06, v:3.1.3) April Gibson: Mapping checks to WCAG guidelines
We've selected specific WCAG 2.1 success criteria to prioritize for our product, and I'm trying to use WAVE to test against only those criteria. Is there any way to see which criterion each check in WAVE maps to? E.g., how do I know which section in WAVE satisfies WCAG's "Success Criterion 1.3.5 Identify Input Purpose"? Thanks!

- (2021-03-26, v:3.1.3) Gabrielle Beaudoin: Chrome Extension Questions
Is there a way to download a report? Is there a maximum number of pages I can scan at any given point?
- (2021-03-25, v:3.1.3) Warren Galyen: Error reporting inconsistency
I'm seeing vastly different numbers when running this extension vice running the same webpage through your website: https://wave.webaim.org/ For example, the extension is reporting only 2 errors but your website is reporting 9 errors and 3 contrast errors on the same page. This inconsistency exists across all the pages I've tested on my site.
- (2021-02-10, v:3.1.3) David Brown: I love your extension but it doesn't work on my page
You extension works on my default page but not my more detailed pages. How can I figure out what is going on? On the WAVE summary, all counts are "?" question marks.
- (2020-12-08, v:3.1.3) Marion Hansford: Download Wave Report

Thanks for a great tool. We are getting contrast errors on some buttons that have fontWeight: 600. If i change our code to fontWeight: bold, the button looks identical - and then passes your tests. Is this an accessibility issue or an issue with this extension?

I am working on a confidential site that only has access through a portal. I want to use your tools locally to test accessibility but I need written confirmation that you don't pull the content of the sites. When I say content I mean the actual text people would read when they are viewing the site. Can you please confirm?
- (2020-05-06, v:3.0.5) Laurel Horn Elgin: WAVE tool in google docs/slides
When I try to use the WAVE tool in google docs it sends an error message: "Unable to load file. Try to load it again or send an error report." When I select re-load file and then activate the WAVE tool again it comes up with the same message. The problem has persisted across google docs and slides. If I select "styles off" in the WAVE tool, all of the content disappears from the page, only the error labels remain, so I have no orientation for review.

- (2019-12-02, v:3.0.4) Mark Cyrulik: Allow ability to move WAVE report panel..
Would it be possible to have an option to move the results panel around? Similar to developer tools, allowing it to be anchored to the left, right, bottom, would be really helpful. We have some social share links that are pinned to the left edge of the screen, and these are not visible when the panel is there.

- (2019-10-31, v:3.0.2) Brian Burrier: Error in checking accessible menus. Incorrectly flagging menus with ARIA labels.
Since the latest update, the WAVE tool is incorrectly flagging errors for “Broken AIRA menu”. In fact, it’s flagging the errors on the W3.org’s own website examples of accessible menus. My speculation is the tool now is only searching one level below the aria-label=“menu” and not getting to the "menuitems". Check the WAVE tool on the W3.org site and you’ll see what I mean: https://www.w3.org/TR/wai-aria-practices/examples/menubar/menubar-1/menubar-1.html
