diffEnvs is a free Chrome extension developed by JoeSaad.net of Amplios Labs. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension is designed to help developers and content editors differentiate between different environments they work on, such as development, staging/testing, and production.

With diffEnvs, users can easily theme their different environments, allowing for a better user experience and preventing confusion about the environment they are currently working on. This is particularly useful for professionals who frequently switch between different environments throughout the workday.

The latest version of diffEnvs, 2.2.0, includes an update for the color picker and various code cleanups and minor fixes. In earlier versions, there were bug fixes for OSX, changes in default colors, and the addition of environment names. Users can also customize the colors for each environment, add as many environments as needed, and use the "Use Default Colors" feature to standardize the colors within a team. Additionally, diffEnvs allows users to remove older sites that are no longer in use and provides URL linking for quick access to different environments.

Overall, diffEnvs is a valuable Chrome extension that simplifies environment differentiation and enhances productivity for developers and content editors.
