The Switcherchange Domain

One-click domain switcher for Production, Staging, and Development (Local) environments.
This Chrome extension allows you to switch between environments with a single click while preserving the current page's URL path and query parameters. By clicking the icon (or pressing Ctrl+Shift+↑), all registered environment URLs are listed, allowing you to move between them without copying and pasting.

Perfect for situations like:

Opening a page you're viewing in production directly in your local or staging environment.

Eliminating the manual task of retyping URLs for different environments.

Quickly comparing the same page (product details, articles, etc.) across multiple domains.

Simply register your project name and domains in the options screen. It supports multi-domain and multi-project setups. Highly recommended for web coders, frontend engineers, web directors, and anyone frequently jumping between environments.
