Frequently asked questions
What are digital accessibility testing tools?
Digital accessibility testing tools help designers, members of dev teams, product owners, and others check web pages, mobile applications, and other digital content against accessibility standards to help ensure they are accessible for everyone, including people with disabilities.
Do automated accessibility testing tools replace manual accessibility testing?
No, automated testing complements manual testing. Automated accessibility testing tools enable testers to quickly identify a high percentage of issues—up to 80% with Deque’s tools. Manual testing can then be used to focus on more complex issues that automation alone can’t detect.
Does Axe DevTools replace screen reader (JAWS, NVDA, TalkBack, and VoiceOver) testing?
No. While automated and semi-automated tests can eliminate a large percentage of issues that may affect screen readers, manual testing with screen readers is sometimes still required to be completely certain that all potential issues have been addressed.
How does Axe DevTools compare with Google Lighthouse?
While Axe DevTools and Google Lighthouse can both be used for assessing digital accessibility, Lighthouse is a more general tool, whereas Axe DevTools is more comprehensive and purpose-built for accessibility. Google Lighthouse has actually run on Deque’s open-source accessibility library, Axe-core, since 2017, but does not run the full set of over 70 tests that Axe DevTools does.
Who is Axe DevTools for?
Axe DevTools is for any organization that wants to create more accessible digital experiences for their users. In particular, web development teams and agencies who need to understand and pinpoint accessibility issues in the context of a fully rendered page; mobile app development teams and agencies who need to enable proven user initiated or automated mobile testing as a part of the release cycle; test engineers who need to seamlessly run accessibility testing as part of their regular build tests; and development leaders who need to incorporate consistent standards, rules, and testing across the SDLC.
What Axe DevTools free trials are available and how can I get started?
We offer many free trials of our accessibility testing tools, including the Axe DevTools Extension for interactive testing in your browser and the Axe DevTools Linter for Static code analysis to stop accessibility bugs immediately.
Why do Evinced and other tools claim to catch more issues?
These are misleading claims. While these tools may appear to catch more accessibility issues overall, the reality is that a high percentage of them aren’t actually issues—they’re false positives (e.g. flagging text that’s purely decorative).
False positives waste valuable time, because developers have to validate every single issue to determine whether they actually need fixing. With Deque’s commitment to zero false positives, you don’t have to worry about this, and can be confident your team is fixing true accessibility issues, not wasting time.
Comparative reviews with accessibility experts who help set WCAG standards highlight this problem. Inaccurate results waste developer time, lead to testing abandonment, and can undermine the credibility of accessibility leaders recommending these tools and practices.
