I built a live secret scanner for VS Code (and why CI scanning is too late)
Short summary
Launched Secret Guardian, a free VS Code extension that detects 17+ secret types (AWS, GitHub, Stripe, OpenAI tokens and more) in real-time as you type, visually masking them to prevent accidental commits. Combines pattern matching for known formats with entropy and context analysis for unknown secrets. All processing is local—100% private, nothing leaves your machine.
- •Free VS Code extension detects 17+ secret types in real-time
- •Prevents accidental commits with visual masking and Problems panel alerts
- •100% local processing—all detection happens on your machine with no data transmission
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
