WAVE
Accessibility evaluator that identifies WCAG-impacting issues and supports human review.
Use it when
Designers and frontend developers who want a fast reality check before shipping a page.
Why this is powerful
- Highlights issues directly on the page so teams can connect problems to visible UI.
- Focuses on accessibility problems that affect real users, not only automated scores.
- Works as a web tool and browser extension for local or protected pages.
Tradeoffs to know
- Automated accessibility checks still need human review.
