TechStack Identifier is a free browser extension designed for Chrome, Edge, and Brave that simplifies the process of identifying web environments. This tool reads specific meta-tags from the HTML head of a webpage to determine whether the user is in a Staging, Production, or Development environment. The extension updates the browser's toolbar icon by changing its color, badge text, and tooltip, providing instant visual feedback to users.

This lightweight add-on is particularly useful for developers and testers who need to quickly ascertain the environment they are working in. By providing clear visual cues, TechStack Identifier helps prevent mistakes that can occur when working across different environments, ensuring a smoother workflow and better productivity.
