Curbcut and axe DevTools compared
Last updated
axe DevTools is a set of accessibility testing tools by Deque Systems, the company behind the open-source axe-core engine.
Curbcut is one rule set on four surfaces: a browser extension for Chrome, Edge and Firefox, an extension for VS Code, a WordPress plugin and a web app that scans whole sites on a schedule. Its checks use the open-source axe-core engine with our own explanations and fix steps.

A note on automated checks
Automated tools, ours included, find only part of all WCAG failures. Whatever tool you use, test with a keyboard and a screen reader as well, and do not read a clean automated result as proof that a page is accessible.
