About Environment Guard
Environment Guard adds clear visual indicators to your web apps so you always know whether you’re working in production, staging, QA, or development before you act.
Recognize your environment at a glance, switch between environments, and keep production clearly marked.
Add your project URLs once in Settings , then every matching page shows the indicator automatically.
WHAT IT DOES
• Coloured border
Add a configurable frame, 1–4 px wide, around your browser’s viewport in the environment’s colour. It stays visible as you navigate through the app.
• Environment banner
Display a full-width strip or compact floating badge with your project name, environment tier, and a context hint such as “Changes here affect live data.”
• Tab title prefix
Identify environments directly from your browser tabs with prefixes such as “[PRODUCTION] Orders”. The prefix stays in place even when a single-page app updates its title.
• Environment switcher
Jump between production, staging, QA, and development while preserving your current path. Switching to production always requires confirmation.
CUSTOMISABLE COLOURS
Default environment colours include:
• Production — Red
• Staging — Amber
• QA — Purple
Customise every environment’s colour with the built-in colour picker.
QUICK SETUP
1. Open your web app.
2. Click the Environment Guard icon.
3. Enter a project name, choose an environment type, and confirm the base URL.
Configure your environment directly in the popup—no separate settings window required.
Working across multiple environments? Add staging, QA, and development under the same project in Settings. Use the popup switcher to move between them.
