Render Custom Domains

Render automatically provisions and renews TLS certificates (via Let's Encrypt and Google Trust Services) for all custom domains. All HTTP traffic is redirected to HTTPS. Custom domains work on web services and static sites only.

When to Use

• Adding a custom domain to a web service or static site
• Configuring DNS records (CNAME, A, or ALIAS) with a provider
• Setting up a wildcard domain (*.example.com)
• Troubleshooting certificate issuance or domain verification failures
• Choosing between apex (example.com) and www (www.example.com)
• Disabling the onrender.com subdomain after adding a custom domain
