A11ygator is a free tool for web developers to check compliance with the WCAG rules. Once the extension has started, it will observe for content changes in the HTML document and it will generate a report with errors, warnings and notices.

Thanks to the integration with DevTools, it is easy to inspect elements and quickly update CSS rules or HTML attributes in order to match the required WCAG standard.

Not so comfortable with dev tools? Check out the Web version.
