What We Scan For:

Our free API key security scanner tool uses 150+ patterns to detect exposed credentials including:

  • • API keys and secret tokens
  • • Database connection strings
  • • OAuth credentials and JWT tokens
  • • Private keys (RSA, SSH, PGP)
  • • Cloud provider credentials (AWS, Google, Azure)
  • • Payment gateway secrets (Stripe, Square)

Best Practices to Secure API Keys & Prevent Key Exposure

Secure Environment Variables Usage

Never hardcode API keys in source code. Use environment variables (.env files) and ensure they're in your .gitignore. Prevent API key exposure in production by keeping .env files server-side only.

Rotate and Revoke Exposed API Keys Immediately

If you detect exposed API keys on websites, rotate them immediately. Don't wait - attackers can exploit leaked credentials within minutes. Use secret management tools like AWS Secrets Manager or HashiCorp Vault.

Automated Secret Detection for Frontend

Enable automated secret detection in your CI/CD pipeline. Tools like Gitleaks, TruffleHog, and our scanner help you find leaked credentials in code before deployment. Scan every commit for credential leaks.

Protect Your API Keys from Leaks

Use API key restrictions (IP whitelisting, domain restrictions, rate limits). Split keys by environment (development, staging, production). Never commit secrets to version control, even in private repositories.

Frequently Asked Questions

How does this free API key security scanner work?

Our scanner performs automated secret detection by fetching your webpage and checking 17+ common locations (including .env files, config directories) using 150+ regex patterns. It identifies API keys, tokens, database credentials, and private keys from AWS, Google, GitHub, Stripe, OpenAI, and 140+ other services.

What should I do if I find leaked credentials in code?

Immediately rotate and revoke exposed API keys through your service provider's dashboard. Remove the secrets from your codebase, add them to environment variables, and redeploy. Check your git history for the leaked credentials and consider rewriting history or rotating all historical keys.

Can this scanner prevent API key exposure in production?

Yes! Use our free scan before deploying to production. Better yet, integrate automated secret detection into your CI/CD pipeline to catch credential leaks before they reach production. Regular security scans help protect your API keys from leaks and unauthorized access.

Is this security scanner really free?

Yes, our API key security scanner is completely free with no signup required. We provide this free security tool to help developers protect their applications from credential leaks and security breaches.

What types of secrets can you detect?

We detect 150+ secret types including: AWS access keys, Google API keys, GitHub tokens, Stripe keys, OpenAI/Anthropic API keys, database connection strings (PostgreSQL, MongoDB, MySQL), JWT tokens, OAuth secrets, private keys (RSA, SSH, PGP), and many more. Our secret detection covers all major cloud providers, payment processors, and development tools.

Does scanning store my URL or detected secrets?

No, we do not store any URLs or detected secrets. All scanning is performed server-side in real-time and results are only returned to you. Your data is never logged or persisted.
