WAVE is a web accessibility evaluation tool developed by WebAIM.org. It provides visual feedback about the accessibility of your web content by injecting icons and indicators into your page. No automated tool can tell you if your page is accessible, but WAVE facilitates human evaluation and educates about accessibility issues. All analysis is done entirely within the Chrome browser allowing secure valuation of intranet, local, password protected, and other sensitive web pages.
To run a WAVE report, simply click on the WAVE icon to the right of your browser address bar, or select "WAVE this page" from the context menu.
WAVE errors align with WCAG 2.1 failures. The WAVE interface facilitates human evaluation of many other aspects of accessibility and Web Content Accessibility Guidelines and Section 508 compliance.
