Accessibility Checker for Developers in Chrome

Image from store axe - Web Accessibility Testing
Description from store Accessibility checker for WCAG 2 and Section 508 accessibility. Find accessibility defects on your website or web application by using the axe Chrome extension. Drop the axe on your accessibility defects! The axe accessibility checker for Chrome is a fast, lightweight accessibility testing tool that 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. The axe Chrome extension utilizes the axe open source JavaScript library developed by Deque Systems – the third generation of accessibility rules for HTML-based user interfaces. The axe library differentiates itself from other approaches and rules repositories in the following ways: 1. It works on all modern browsers, 2. It supports in-memory fixtures, static fixtures, integration tests and iframes of infinite depth 3. It has zero false positives (bugs notwithstanding) 4. It is open source (the axe-core library, not the extension) 5. It is actively supported by a major accessibility vendor 6. It is designed to work with whatever tools, frameworks, libraries and environments you have today 7. It is designed to be integrated into your existing functional/acceptance automated tests 8. It automatically determines which rules to run based on the evaluation context 9. It is highly configurable (as a JavaScript API) Use of this extension is governed by this license agreement https://www.deque.com/terms-of-use/axe-ext/ and the privacy policy linked under the developer information

  • (2020-03-21) Richard Brus: An awesome accessibility testing tool. Works beautifully on local files as well. Great job!
  • (2020-03-02) Marvin Heilemann: Best way to check for accessibility but lacks good design and I'm getting this error always: `DevTools failed to parse SourceMap: chrome-extension://lhdoppojpmngadmnindnejefpokejbdd/browser-polyfill.js.map`
  • (2020-02-24) Ferran Buireu: Funciona bastante bien, pese a que no acaba de apurar en muchos sites, estéticamente está bastante mejor que las de la competencia y tiene margen de mejora. Funciona bien.
  • (2020-02-07) Riwert: Good purpose is in this extension but my anti virus on Linux found Html.Exploit.CVE_2016_0228-6327291-2 in vendor.bundle.js file in it :O
  • (2020-01-02) Adam Beck: Good insights, however it crashes easily 1/3 of the time, even freezing up the Chrome tab so I can't close it.
  • (2019-07-17) Liron Navon: The extension is working with axe-core 3.2.2, but I use the selenium driver which uses 3.3.0 - those mismatches make it so in testing and production we get different errors.
  • (2019-07-12) qapisqltest qapisqltest: Hi, everyone. I have question about report. Is there a function to upload a report to my computer? Thanks.
  • (2018-10-26) Kitty Hurley: Fantastic tool!
  • (2018-08-12) Edgar Clement: works great, my team uses the javascript api to automate accessibility testing and this extension while manually fixing issues.
  • (2018-06-28) Jose Jorge Garcia Almajano: The best tool that I have found
  • (2018-06-25) Justin Ross: Quick and easy. Detects many accessibility issues and provides information about the violated rule.
  • (2018-05-04) Michael Spellacy: This tool has become indispensable in my work. Thank you.
  • (2018-04-13) jose ramon: No funciona al abrir con Chrome archivos html locales (file://...), sólo con paginas alojadas en un servidor (http://...). Sin embargo la versión para Firefox sí funciona también sobre archivos. Deberían revisar la versión para Chrome.
  • (2018-04-02) Aaron Diffenderfer: While this tool provides some overall good value at a basic level, it's biggest weakness/limitation is that it only analyzes static content. This is very prohibitive in this day/age where nearly all sites are dynamic. Not being able to test actions and dynamic content on a page is a big disappointment as well as not traversing an entire site. Earlier Fireeyes versions allowed it but functionality has been removed over time.
  • (2018-01-11) Trying this after watching Marcy Sutton's talk at Generate NY. Looks really useful.
  • (2017-11-16) Jeremy AAsum: A great tool. Noticing that it is always active though, even if not using the inspector in Chrome. It would be nice if it only ran when hitting the "analyze" button. This causes some strange javascript issues when enabled and simply browsing around.
  • (2017-11-13) Mike Farrell: Great plug in with no false positives - so no wasted time chasing down "non bugs".
  • (2017-08-15) Timmee Artchel II: This tool is good for multiple reasons! 1. Works with intranet sites that other checkers don't have access too. 2. Usable by engineers because it will show the html for each item and provide suggestions. 3. Usable by non-engineers because it does highlights.
  • (2017-06-30) Raúl Martín: La nueva actualización le da un aspecto genial. Pero especialmente me gusta la nueva opción para resaltar el elemento dentro de la página. Siempre usaba la opción the inspeccionar pero ahora es mas fácil. No tengo que salir de la pestaña de Axe.
  • (2017-06-23) William Buchanan: Definitely a nice addition to the space for accessibility testing, but is incorrectly detecting colors used for color contrast ratios.
  • (2017-01-27) Preston Welch: Great detection on everything *but* it throws tons of false positives for color contrast issues. I'm not sure how it's pulling foreground and background color values for the elements it flags, but one or both tend to be wrong enough for me to ignore the color contrast violations altogether.
  • (2017-01-24) Emanoel Lopes: I hope it helps me searching for a11y issues.
  • (2016-12-22) Homer Gaines: This is my goto plugin for automated ADA tests. It's clean and doesn't return the false positives that some other plugins spit out. This helps me and my teams focus on the real issues.
  • (2016-11-28) Paul Adam: aXe is an excellent automated accessibility testing tool that does not report false positive issues that are not real accessibility problems. I use aXe in Chrome Canary, Firefox, and also in Safari through the aXe JavaScript library in the Console.
  • (2016-11-28) Glenda Sims: Great tool for showing real WCAG failures. Excellent support materials that explain how each rule works, how to fix the problem and other helpful resources for learning.
