New: CheckVibe MCP server — scan from Claude Code and Cursor nativelyRead the docs
Replit Agent ships in minutes. Production security takes hours.
Replit Agent builds and deploys a working app astonishingly fast. The catch: it deploys on Replit's default config, and that config is optimized for "it works" not "it's hardened." Most Replit-deployed apps we scan are missing headers, rate limits, and proper secret handling.
Get a graded security report for your Replit Agent app in under a minute.
Replit's default error handler leaks file paths and dependency versions.
Some Replit secret types end up in the bundle. CheckVibe scans for them.
No CSP, no HSTS, no Permissions-Policy by default.
Default deploy allows any origin.
Replit runs your app on the Nix pin you generated with — easy to fall behind on patches.
Strip stack traces from public responses.
CheckVibe scans the deployed bundle for each one.
Five lines of middleware solves most of this.
Replit-deployed apps inherit defaults; override them.
Out of the box, it's designed for prototyping. Hardening for production is your responsibility.
Paste your deployed URL into CheckVibe — we'll scan the bundle for exposed keys.
