Domain, DNS & TLS
for Replit

What you need to verify

For Replit apps, domain, dns & tls requires explicit attention. You must own your domain and DNS — never rely on a builder-provided URL for production.

1. Identify which service owns this layer in your Replit stack.
2. Separate preview and production configuration.
3. Verify failure behavior and owner alerts.
4. Document export or migration path.
5. Test with a non-admin user and real domain.

Common Replit mistakes for Domain, DNS & TLS

• Assuming Replit handles this automatically
• Using the same configuration for preview and production
• Not testing failure scenarios
• Forgetting to set up monitoring and alerts
