🔒 Automatically detect and mask sensitive information in your code — without modifying files.
Features
🎯 Pattern-Based Detection
Automatically detects known secret formats:
- AWS - Access Keys (
AKIA...)
- Stripe - Live & Test Keys (
sk_live_..., sk_test_...)
- GitHub - Personal Access Tokens (
ghp_..., github_pat_...)
- Google/Firebase - API Keys (
AIza...)
- JWT - JSON Web Tokens
- Private Keys - RSA, EC, SSH keys
- And many more...
🧠 Context-Aware Detection
Goes beyond regex with intelligent analysis:
- Recognizes sensitive variable names (
API_KEY, SECRET, TOKEN, etc.)
- Understands assignment patterns (
=, :, =>)
- File type awareness (
.env, .json, .yaml, config files)
👁️ Visual Masking
Non-destructive protection for your secrets:
- Overlay masking with
•••••••• - file contents remain unchanged
- Per-secret toggle - click the gutter icon to reveal/hide individual secrets
- File-level toggle - show/hide all secrets in current file
- Hover to peek - see obfuscated preview on hover
- Temporary reveal - auto-hide after 5 seconds
📺 Screen Share Mode
Perfect for streamers, educators, and presenters:
- One-click activation -
Ctrl+Shift+S
- Instantly masks ALL secrets
- Partial URL hiding (
https://api.***.com)
- Persistent status bar indicator 🔴
⚙️ User-Defined Rules
Customize detection for your needs:

- Specify variable names to always hide
- Define literal strings to mask
- Import/export configurations
