A Visual Studio Code extension that helps you safely preview .env files by blurring sensitive values until you choose to reveal them.
Ideal for live demos, screen-sharing, or collaboration where configuration data should remain private.
✨ Features
🔒 Blur sensitive values in .env files automatically
👁️ Click Reveal to temporarily show values (auto-hides after a timeout)
⚙️ Set Env Protector as the default editor for .env files
🧩 Toggle between blurred preview and plain text view at any time
🧼 Works completely offline — no network, no telemetry
🚀 Getting Started
Install Env Protector from the VS Code Marketplace.
Open any .env or .env.* file — it will appear blurred by default.
Click Reveal to view values temporarily.
Click Hide (or wait for the timeout) to blur again.
You can configure behavior in VS Code Settings → Extensions → Env Protector:
envGuard.autoReplaceWithPreview: Automatically open .env files in blurred preview.
envGuard.revealTimeoutSeconds: Time in seconds before values auto-hide.
🧱 Why Env Protector?
When recording videos, sharing your screen, or pairing with teammates, .env files often contain private tokens and credentials.
Env Protector gives you a safe local preview so you can display configuration files without revealing private data.
🔐 Privacy & Security
Env Protector runs entirely on your local machine.
No data is uploaded, transmitted, or stored externally.
The extension does not make network requests.
Clipboard operations are strictly local.
No telemetry or analytics are collected.
✅ Your .env data never leaves your device.
