Custom Domains for Cloud Development Platforms

Why custom domains matter for cloud development and app deployment platforms

The first thing a developer wants after their app runs is a real domain on it. If the only option is yourapp.dev/u/acme/myapp, they outgrow your platform the moment they ship something they care about. Custom domains turn your platform from a sandbox into infrastructure they keep paying for.

What your users get

• Apps live at the developer's own domain
• Apex domain support (acme.com, not just www)
• TLS for free, forever, with no cert chores

How it works in 3 steps

1. Your user types their hostname (app.acme.com) into your UI.
2. your dev platform POSTs to the Domainee API to register it and gets back the CNAME the user needs to add at their DNS provider.
3. We monitor DNS, issue the cert via Let's Encrypt, and webhook back when it's live. Usually about 60 seconds.

The code

curl -X POST https://api.domainee.dev/v1/domains \
  -H "Authorization: Bearer $DOMAINEE_API_KEY" \
  -H "content-type: application/json" \
  -d '{
    "hostname": "app.acme.com",
    "originUrl": "https://app.your-saas.com",
    "mode": "proxy",
    "redirectWww": true,
    "metadata": { "workspaceId": "your-internal-id" }
  }'

The response includes a dnsRecords array (usually one CNAME). Show that to your user, tell them to paste it at their DNS provider, and we'll handle the rest.
