Finally, a resource that cuts through the fluff and gives you exactly what you need for ARIA and WCAG testing right away.

Really handy for checking keyboard interactions and focus management rules quickly. The interactive demos make it easy to see exactly how components should behave. It’s a great supplement to the official W3C specs for day-to-day development.

The breadth of coverage across ARIA attributes, roles, and WCAG criteria is impressive. Having step-by-step test guides and expected screen reader outputs for JAWS, NVDA, and VoiceOver in one place saves considerable time during accessibility audits. The downloadable cheat sheet is also a practical addition for quick reference during daily work.

For anyone building accessible interfaces, this site offers a direct approach to understanding ARIA roles and WCAG criteria. The toggle between developer and tester modes is a thoughtful feature, allowing teams to quickly switch between implementation details like keyboard interactions and screen reader announcements. While the scope is clearly defined as a reference rather than a comprehensive training course, the curated list of components and code examples provides a reliable starting point. The fact that it is free and open source adds significant value for teams looking to streamline their accessibility audits without sifting through dense documentation walls. It seems particularly well-suited for practitioners who need to verify specific attributes or test procedures on the fly during development sprints. One might appreciate the inclusion of a colour contrast checker and the mapped success criteria, which help bridge the gap between theoretical standards and practical application. Overall, it serves its purpose as a quick, accurate guide for those already familiar with the basics of web accessibility.

This resource is incredibly useful! The split developer and tester modes make finding ARIA roles so much faster than digging through long docs.
