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!

Great add-in. I've put in a feature request for a "mouse over transparency" feature, which would solve the only thing I wish it did.
Lifesaver. Would be nice if it changed the tab color too!
Замечательное расширение. Не думал что найду то, что мне нужно)
Exactly what I was looking for. Love you man. I only wish it could be sized up.
Very useful extension!
simple and useful
Very useful!
Thanks for this extension, it's very helpful! One small suggestion: it would be nice if the "hide label" action could keep the state between page refreshes. That would be really useful, for example, when checking pages on small screen sizes, where the label can really get on the way, and hiding it after every page refresh is a bit annoying.
Really nice, but add transparency to able to see button below banner.
very nicely done! only issue i have is that no matter what corner i place it in, at some times it blocks what I should see. It would be nice to have a transparency option in the settings. Or a way to temporarily hide it by clicking on it.
