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!

This a very nice app. no more production screw ups. I have an internal application like "https://admin.mycompany.info/admin/index.jsp. I have added marker for this environment. but it is still not showing the marker. I think it is not recognizing the domain. Please check.

Man, this extension is great! Helps me keep my sanity when working on different servers/environments. I only wish we could adjust the thickness of the "Moldure/Border" position. But the ability to adjust the transparency has been helpful in its absence! Thanks!
