What is Who Can Use?

Who Can Use is a free and open source browser extension available for Chrome, Firefox, and Edge. It helps evaluate if websites comply with web accessibility standards by injecting colorful icons and indicators that reveal accessibility information about elements on each page.

As you browse the web, Who Can Use will highlight page elements to show if they meet criteria for visual accessibility, keyboard accessibility, screen reader accessibility, and more. Some examples of what it checks for include:

• Sufficient color contrast for text
• Appropriate alternative text for images
• Logical heading structure
• Logical focus order for keyboard users
• ARIA landmark roles for screen readers

Web developers can use Who Can Use to test their own sites during development. It helps identify areas that need improvement to comply with guidelines like WCAG 2.1. Non-developers can also install Who Can Use while casually browsing to get insight into the accessibility of pages they visit.

With colorful icons displayed right on each page, Who Can Use makes website accessibility testing easy and intuitive. It empowers both developers and users to evaluate inclusion for people with disabilities.
