Frequently Asked Questions

Is my code uploaded to a server?

No. All pattern matching runs locally in your browser using JavaScript regex. Your source code never leaves your device.

What types of secrets does it detect?

It detects AWS keys, GitHub tokens, Google API keys, Stripe keys, Slack tokens, private keys, database URLs, JWT tokens, npm tokens, SendGrid keys, Twilio SIDs, and generic API key/secret patterns.

What should I do if it finds a secret?

Immediately rotate (regenerate) the exposed credential in the respective service's dashboard. Then remove it from your code and use environment variables or a secrets manager instead.

Is this a replacement for tools like GitLeaks?

This is a quick pre-commit check for individual files. For comprehensive repository-wide scanning, we recommend also using GitLeaks, TruffleHog, or GitHub's built-in secret scanning.
