Deque axe DevTools

Axe DevTools from Deque provides automated accessibility testing for developers, part of a wider Axe platform spanning Axe Auditor for systematic manual testing, Axe Monitor for site-wide scanning and reporting, and an Axe MCP Server offering one-click fixes inside an IDE.

Building on the open source axe-core engine is the foundation of Deque's position, and it explains why axe has become the de facto standard rule set. Because the engine is open and widely embedded, an axe violation is a shared reference point that a developer, an auditor and a legal team can all point at, rather than one vendor's opinion. That common language matters enormously in a field where the underlying standard, WCAG, requires interpretation.

Meeting developers in their own tools is the second principle. Accessibility defects found in a quarterly audit arrive months after the code was written, when the developer has moved on and fixing them means reopening finished work. Found in the IDE or the browser devtools while the component is being built, the same defect is a minor correction. The Axe MCP Server extends that to AI-assisted development, where accessibility risk in agentic coding is called out explicitly as an emerging concern.

Automated testing catches a meaningful but bounded share of accessibility problems, which is why Axe Auditor exists for systematic manual evaluation and why Deque is careful to position the two together rather than implying automation is sufficient. Axe Monitor handles site-wide scanning, reporting and business intelligence for programme-level oversight. The platform is published in English, German and French. Pricing is not published.
