Axe DevTools
Automated and AI-assisted accessibility testing tools for web and mobile developers.
Best for
Teams that need to catch WCAG accessibility issues automatically and wire checks into CI/CD.
Skip if
You only need a one-off manual accessibility audit rather than ongoing automated testing.
What is Axe DevTools?
Axe DevTools is Deque Systems' accessibility testing product line, built on top of axe-core, the open-source accessibility testing engine that Deque also maintains. The free browser extension lets developers run automated, page-by-page accessibility scans directly in Chrome, while the Linter and CI integrations catch issues earlier in the development process. Paid tiers add Intelligent Guided Tests that combine automation with structured human review to catch issues automated scanners miss, component-level testing, Jira integration for tracking fixes, and an MCP server plus API for wiring accessibility checks into custom workflows. The tools integrate with common web and mobile test frameworks including Cypress, Selenium, Puppeteer, Jest, Appium, XCUITest, and Espresso.
