Frequently Asked Questions

Often referred to as digital accessibility testing tools, they exist to surface usability barriers for people with disabilities so that they can be fixed. There are a range of tools which help accomplish this. Some are automated or semi-automated and can test for specific barriers and others a wide array. It’s important to select a tool that avoids creating false positives, which wastes valuable development time.

There are 3 types of accessibility testing. 1) Automated- like when a rules engine like axe-core, scans, or analyzes a web page against accessibility standards, such as WCAG. 2) Semi-automated- sometimes referred to as guided testing, like the Intelligent Guided Testing (IGTs) in axe DevTools which rely on question and answer prompts. 3) Manual- when an accessibility expert uses assistive technology (such as a screen reader) and lived experiences to catch complex accessibility barriers that automation is unable to reliably detect.

Web accessibility testing tools that are build on axe-core are the best in the world. The axe Linter for VS Code is a popular free static code analysis tool used by over 20,000 developers. The free axe DevTools browser extension is available in Chrome, Firefox and Edge and is used by hundreds of thousands of people around the globe to catch accessibility errors.

Another popular free tool is Google Lighthouse, which is also powered by axe-core.

Apple and Google provide limited support for accessibility testing of mobile applications with their tools: Accessibility Inspector built into Xcode and Google Scanner on the Play Store. While these tools are free, they won’t capture the same issues and coverage may not align with WCAG’s guidelines.

Deque offers native mobile accessibility testing with axe DevTools Mobile for iOS and Android. Learn more about iOS or Android mobile accessibility testing tools.
