Select the platform that best fits your infrastructure needs and follow the platform-specific guide below.
Store Replit API keys securely using the platform's secrets management.
Use the platform CLI to deploy your application with Replit integration.
Test the health check endpoint to confirm Replit connectivity.
| Issue | Cause | Solution |
|---|---|---|
| Secret not found | Missing configuration | Add secret via platform CLI |
| Deploy timeout | Large build | Increase build timeout |
| Health check fails | Wrong API key | Verify environment variable |
| Cold start issues | No warm-up | Configure minimum instances |
