description WAVE Web Accessibility Evaluation Tool Overview
WAVE, developed by WebAIM, is a free, online web accessibility evaluation tool. While not a full-fledged testing suite, the free trial (essentially unlimited use) provides a visual representation of accessibility issues directly on the webpage. It identifies WCAG 2.1 errors and alerts, and provides a clear visual map of accessibility problems. WAVE is excellent for quick, visual assessments and for educating developers and content creators about accessibility principles.
It's a great starting point for anyone new to accessibility testing and is particularly helpful for content editors.
