We at Deque Systems built axe DevTools for Web to make it easy for you to integrate automated testing for accessibility into your development process. We believe that preventing accessibility defects by adding automated testing for accessibility is the most efficient and sustainable way to create accessible products.

Axe DevTools for Web is built on top of our axe-core product, which is the most popular open-source accessibility testing engine.

If you are interested learning more about our vision for accessibility, read the axe-core Manifesto and the Philosophy on which the axe-core engine is built.

The Components of axe DevTools for Web

Axe DevTools for Web is comprised of the following components to enable you to integrate accessibility testing into different points in your development process.

axe DevTools Linter: Spot Accessibility Issues as You Code

You can download the axe Accessibility Linter for VS Code from the VS Code Marketplace. Use it while you are writing code so you can be alerted to accessibility issues immediately, just like any other linter.

note

Deque has a separate linter product called axe DevTools Linter that allows you to lint source via an on-premises server or a software as a service (SaaS) product. See the axe DevTools Linter Documentation for more information.

axe DevTools Browser Extension: Check Accessibility from Your Browser

The axe DevTools Browser Extension can be downloaded directly from the Chrome web store, Edge Add-ons site, and Firefox add-ons site. Use this extension (which integrates into each browser's Developer Tools) to catch as many as 80% of all accessibility defects.

To learn more about getting started and using the axe DevTools browser extension, see this video playlist.

APIs: Automate Your Accessibility Testing

The axe DevTools for Web APIs are designed to help you automatically test for accessibility as part of your existing automated UI (end-to-end) testing process. You can use our APIs in tests where you use browser drivers like Selenium, Puppeteer, or Playwright and testing frameworks like Cypress, Jasmine, Jest, JUnit, Karma, Protractor, Robot Framework, unittest, and many others—giving you the ability to use our packages to help you find accessibility problems during your CI process.

To find which axe DevTools HTML package you need to use with the test drivers or test frameworks you already use, look at our Examples Catalog. That page will not only help you identify the package you need but will also point you to an example project that you can clone from GitHub and run locally. We recommend you do this first. Once you have the example working locally, it will be easy for you to include automated accessibility testing in your own project.

CLI: Check Accessibility from the Command Line

If your team does not yet have a lot of automated UI testing, the axe DevTools for Web CLI might be a good option to include accessibility testing for some important user flows in your website or web application. The axe DevTools for Web CLI can be scripted to load specified pages (through its built-in scripting language), fill out forms, log in with test-user credentials, and expose different states of pages built with React, Vue, Angular, and other such frameworks. It can also be very valuable for automatically testing responsive sites at different breakpoints. To get started with the axe DevTools for Web CLI, read the Quick Start Guides.
