Visual cues for production, staging and development.

Every environment looks the same in the browser: same URL bar, same layout, different
database. That's how a config change ends up in production.Env Guard draws a colour-coded border around the sites you choose, so you can see which environment you're in before you touch anything.

Features:

• Colour-coded borders for production, staging, development or QA sites
• Wildcard or regex URL matching — one rule can cover a whole subdomain
• Custom border colour and width (1–20px), so prod can shout and staging can whisper
• Rules sync through your Chrome profile — set it up once, ready on every machine
• Nothing leaves your browser: no analytics, no tracking, no servers of mine
