JavaScript Security & Secrets Scanner
Protect your application by identifying exposed secrets, API keys, and tokens in your client-side JavaScript. Prevent accidental data leaks and unauthorized access to your third-party services
Client-Side Security Scan
Modern bundlers — webpack, Vite, esbuild — make it trivially easy to accidentally ship server-side secrets in client code. Our scanner parses your production bundle to surface tokens, keys, and credentials that have no business being in a browser
🔍 We Detect
- Exposed AWS Access Keys
- Google Cloud API Keys
- Stripe Publishable/Secret Keys
- Slack & Discord Webhooks
- Private Keys (RSA, PEM)
- Database Connection Strings
- ...and 15+ more checks
✨ Security Benefits
- Prevent data breaches before they happen
- Avoid expensive cloud resource theft
- Protect user data privacy
- Ensure compliance (GDPR, SOC2)
- Secure your third-party integrations
💡 Security Tip
Never commit `.env` files. Use environment variables and proper CI/CD secrets management. If a key is exposed in client-side code, assume it is compromised
Security FAQ
Is it safe to paste code here?
Yes. The analysis happens entirely in your browser. We do not store or transmit your code or the keys we find to any server
What should I do if I find a key?
Revoke the key immediately in the respective service dashboard (e.g., AWS Console). Rotate the credentials and update your application to use environment variables
Can I use this for backend code?
This tool is optimized for frontend bundles and client-side scripts. For backend code, use server-side static analysis tools (SAST) in your CI pipeline
Are all "exposed" keys dangerous?
No. Some keys (like Firebase config or Stripe Publishable keys) are meant to be public. Our tool attempts to distinguish between public and private tokens
