About this extension
Env Border is a Chrome extension designed to enhance your web development workflow by visually distinguishing between different environments of your applications. By allowing you to input the domains for your local, QA, staging, and production environments, Env Border sets a colored border around the webpage window. This simple yet effective visual cue helps you quickly identify the environment you're currently viewing at a glance.

Features
Environment Recognition: Automatically recognizes the environment based on the domain
Subdomain Support: Matches subdomains automatically (e.g., api.qa.example.com matches qa.example.com)
Color-Coded Borders: Adds a distinct colored border to the window:
- Green for Local
- Yellow for QA
- Orange for Staging
- Red for Production
Custom Domain Input: Allows you to specify the domains for each environment
Toggle Control: Enable or disable the extension with a single click
