Hostnames

Hostnames allow you to serve your application from custom domains instead of default platform URLs.

A hostname is a custom domain or subdomain (e.g., example.com, www.example.com) that points to your application.

  • Domain: The full domain or subdomain
  • App: The application it points to
  • SSL Certificate: Automatically provisioned via Let’s Encrypt
  • Created At: When the hostname was added
  1. You add a hostname to your app via the CLI
  2. You configure DNS to point to the platform
  3. An SSL certificate is automatically provisioned
  4. Your app is accessible via the custom domain

Apps can have multiple hostnames:

  • Root domain and www subdomain
  • Multiple subdomains for different purposes
  • Regional or language-specific domains
  • Alternative domain names

All hostnames automatically receive SSL certificates:

  • Issued via Let’s Encrypt
  • Automatic renewal
  • HTTPS enforced by default
