Environment Marker is a free, open-source Chrome extension designed to help developers and IT professionals visually differentiate between multiple programming environments such as development, QA, staging, and production. It adds customizable colored labels to specified websites based on user-defined URL patterns, reducing costly mistakes caused by working in the wrong environment.

Key features include support for regular expressions to match URLs dynamically, a color picker for personalized label colors, flexible label positioning (top-right, top-left, bottom-right, bottom-left, or moldure), quick configuration mode, and the ability to export and import settings for easy backup and restoration. The extension is easy to set up from Chrome's extension options or via a toolbar icon. Environment Marker enhances workflow protection by making environment identification simple and immediate, preventing accidental production errors.

Pros

Prevents mistakes when working in different environments by clearly marking them.
Simple, easy to use, and effective tool for environment identification.
Highly useful for development teams especially during go-live or deployment scenarios.
Long-time users praise its reliability and usefulness.
Allows quick identification of environment which reduces user errors.

Cons

Lacks customization options such as font size and ribbon size customization.
Missing transparency or mouse-over transparency feature to avoid blocking underlying controls.
Cannot base environment marking on IP address, only on URL which limits some use cases.
Does not retain 'hide label' state after page refreshes which can be annoying on small screens.
Limited placement options; users desire ability to move or position the marker in different screen areas.
