Overview
Product summary
Review the store description, core capabilities, and common use cases.
This extension helps you visually distinguish between different environments by adding a colored label to specified websites based on URL configurations. It supports regular expressions (including wildcards), a color picker, and positioning preferences.
Why Use Environment Marker?
In IT projects, working with multiple environments—such as development, QA, staging, and production—is common. However, since these environments often look identical, mistakes can happen.
Have you ever intended to run a "quick test" in the development environment, only to realize too late that you were actually in production? Misconfigurations and accidental changes can easily occur because the only visible difference is the discreet URL in the browser's address bar.
That is where Environment Marker comes in. This free and open-source Chrome extension lets you define your project’s environment URLs and assign a colored label in the browser window to identify them at a glance.
No more screw-ups in the production environment!
