ChromeLens is a browser extension developed to assist web accessibility development. With it, you can interact with a website as a completely blind or a colorblind person. It includes tools to help you discover elements that don't comply with web accessibility rules, such as websites that rely on visual indicators to convey their meaning. You can then run through a series of rules to determine which elements in a website are not accessible.

It is a tool for web accessibility development, and it does not provide an interface to your actual browser. To use it, you will need Chrome or Chromium, and you will need to have an Internet connection.
