Note: While these testing tools can identify many accessibility and Web Content Accessibility Guideline (WCAG) errors, they are not a replacement for the full WCAG. It is recommended to use these tools to help facilitate human evaluation of web content. |
WAVE
The WAVE web accessibility evaluation tool is available as an API, testing engine and browser extensions for Chrome, Firefox and Edge. Because the extension runs entirely within your web browser, it can check intranet, password-protected, dynamically generated, or sensitive web pages.
