Free Replit security scanner
Replit's Agent can build and deploy a full-stack app from a single conversation. What it deploys is whatever the code says — including debug settings and files that were only meant for development.
What we check on Replit apps
Typical stack: Node.js or Python apps on Replit Deployments
Keys belong in Replit Secrets, not in code or a committed .env. VibeShield checks both your shipped JavaScript and common sensitive file paths.
Server and X-Powered-By headers tell attackers exactly what you're running — VibeShield flags them on every scan. Pro's active checks also probe your API for stack traces leaking from error responses.
A custom domain that still answers over plain HTTP, or never sets HSTS, lets traffic be intercepted. VibeShield checks your TLS setup and redirects.
No Content-Security-Policy, HSTS or clickjacking protection means one injected script or a framing attack goes unchecked. VibeShield tells you which headers are missing and what to set.
