EnvGuard 제작자: Jonas L. Jensen

Never confuse production and development again.

EnvGuard makes your environments instantly recognizable, helping prevent accidental testing, changes, or destructive actions in the wrong environment.

Every website you visit is automatically checked against the environment rules you define and clearly marked:

• 🔴 Production - a prominent red banner across the page that's hard to miss
• 🟡 Development - a striped border around the page
• 🧰 Toolbar badge - shows P or D, so you can identify the environment even when the popup is closed

Whether you're switching between production and development, staging and live, or multiple client environments throughout the day, EnvGuard gives you an immediate visual reminder of where you are before you click, submit, deploy, or delete anything.

Privacy first

All environment rules and settings are stored locally on your device. Nothing is sent to external servers.

Open source

EnvGuard is fully open source, so you can inspect the code, contribute improvements, or build it yourself.

Built for developers and QA

EnvGuard is designed for developers, QA testers, system administrators, and anyone who regularly works across multiple environments and wants an extra layer of protection against costly mistakes.
