Replit Policy Guardrails

Overview

Policy enforcement for Replit-hosted applications. Replit's public-by-default Repls, shared hosting, and resource limits require specific guardrails around secrets exposure, resource consumption, deployment security, and endpoint protection.

Prerequisites

• Replit account with Deployment access
• Understanding of Replit's security model
• Awareness of Replit's Terms of Service

Instructions

Step 1: Secrets Exposure Prevention

Replit Repls are public by default on free plans. Source code is visible to anyone.

# CRITICAL POLICY: Never hardcode secrets in source files

# BAD — visible to anyone viewing your Repl
API_KEY = "sk-live-abc123"
DB_PASSWORD = "p@ssw0rd"

# GOOD — use Replit Secrets (AES-256 encrypted)
import os

API_KEY = os.environ.get("API_KEY")
if not API_KEY:
    raise RuntimeError("API_KEY not set. Add it in the Secrets tab (lock icon).")

# Startup validation — fail fast if secrets missing
REQUIRED_SECRETS = ["API_KEY", "DATABASE_URL", "JWT_SECRET"]
missing = [s for s in REQUIRED_SECRETS if not os.environ.get(s)]
if missing:
    raise RuntimeError(f"Missing required secrets: {missing}")

Automated secret detection:

// Pre-deploy check script: scripts/check-secrets.ts
import { readFileSync, readdirSync, statSync } from 'fs';
import { join } from 'path';

const  = [
  ,     
  ,
  ,
  ,
  ,  
];

 (): [] {
   content = (filepath, );
   : [] = [];

  .( {
     (pattern.(content)) {
      issues.();
    }
  });

   issues;
}

 (): [] {
   : [] = [];
   entries = (dir);

   ( entry  entries) {
     ([, , , ].(entry)) ;
     path = (dir, entry);
     ((path).()) {
      issues.(...(path));
    }   (.(entry)) {
      issues.(...(path));
    }
  }

   issues;
}

 issues = ();
 (issues. > ) {
  .();
  issues.( .());
  process.();
}
.();
