WAVE (Web Accessibility Evaluation Tool) by WebAIM is a tool to help web developers make their web content more accessible. WAVE cannot tell you if your web content is accessible. Only a human can determine true accessibility. But, WAVE can help you evaluate the accessibility of your web content.

WAVE is a browser plug-in for Chrome and Firefox. View the WAVE help page for more help.
