Resources for testing your web accessibility

Free tools and resources recommended by ACCESS for checking and testing your web page or application to improve its accessibility.

There are many free, easy-to-use tools and resources available for checking and improving your digital accessibility. Some can even be added directly to your browser or CMS. This page provides a list of some of these tools that ACCESS recommends using.

WAVE extension (browser extension)

WAVE extension is a web browser extension that helps you identify and evaluate web content accessibility issues directly in your browser. WAVE is a web accessibility evaluation tool for authors.  It can identify accessibility and Web Content Accessibility Guideline (WCAG) errors.  It provides visual feedback about the accessibility of your web content.  Each flagged item has descriptions about the item and how to fix it if that’s an error or alert.  You can learn web accessibility while making your page more accessible.  It’s more friendly to non-technical authors and accessibility beginners. Read more information in the WAVE Guide and on the WAVE Help page.

For Mass.gov CMS users, Editoria11y is more convenient since it has already evaluated your page as you open the page.

ANDI bookmarklet (browser bookmarklet)

ANDI bookmarklet is an accessibility and Section 508 compliance testing tool. Users can optimize the tool when they have basic accessibility knowledge. If you’re new to accessibility, it’s better to use WAVE first and get yourself familiar with accessibility.

Read the ANDI tutorial for more information on using this tool.

Color contrast checker (website tool and bookmarklet)

The WebAIM color contrast checker shows you the color codes and contrast ratio for different text and background color combinations. It also checks the contrast ratio for two given hex color codes. You can use it to check color contrast for text against its background and graphic elements (border, outline, and shapes like icons or button backgrounds) against their backgrounds.


WebAIM also has a Contrast Checker Bookmarklet you can use directly on a web page.
