Preflyt

Scan your deployment for security issues in 30 seconds

Preflyt scans your live web app for common deployment security mistakes. Paste a URL or run npx preflyt-check from your terminal - get a report in 30 seconds.

Built Preflyt because I kept seeing the same deployment mistakes everywhere - .env files exposed, database ports open, security headers missing. The code passes all tests but the live deployment is wide open. Preflyt scans from the outside, same perspective an attacker would have. 30 seconds, paste a URL, see what you forgot to lock down

Scanning deployments for security issues in just 30 seconds is incredibly fast! As a developer, speed is crucial for CI/CD pipelines. Does Preflyt integrate directly with GitHub Actions or other CI tools for automated scans on every push?
