Env Switcher от Ravi

Env Switcher lets you jump between your Dev, UAT, Staging and Prod environments in one click — without hand-editing URLs. It swaps the current tab's domain to the environment you pick and keeps you on the same page: path, query string and #hash are all preserved.

Features
- One-click switching between a project's environments, from the toolbar popup or Ctrl/Cmd + Shift + E.
- Automatic project detection — the popup recognises which environment the active tab belongs to by its domain.
- Path-prefix rewriting for apps served under different base paths (e.g. /v2 → /).
- Toolbar badge showing the current environment (PROD, UAT, …) in its own colour.
- Production guard — mark risky environments to get a draggable on-page warning card and an optional confirm-before-switch prompt.
- Manage unlimited projects and environments, pick colours and emoji, and import/export your config as JSON.
- Settings sync across your devices. No account, no tracking — your configuration never leaves your browser.
