Prod Warning is a free Chrome add-on developed by charlie.fats. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This handy tool allows you to specify a list of domains and displays a border around websites to warn you when you are on a production version of a site.

With Prod Warning, you can easily differentiate between production and non-production sites, ensuring that you don't accidentally make changes or perform actions on the wrong environment. By specifying the domains that should be considered as production, the add-on automatically highlights these sites with a border, providing a visual cue to remind you of their production status.

This simple yet effective feature helps developers, testers, and anyone working with multiple environments to stay focused and avoid costly mistakes. Prod Warning is a valuable tool for maintaining a clear distinction between production and non-production sites, ensuring a smoother workflow and preventing accidental errors.
