Custom Domains for Website Builders

Let users publish their site at their own domain. Add custom domains to your website builder with one API call.

Why custom domains matter for website builders

Every website builder eventually competes on "how easy is it to use my own domain?" Wix, Squarespace, and Webflow built this in-house and it took them years. With Domainee you ship the same experience in a sprint, on every plan tier you want, without staffing a TLS team.

What your users get

  • Sites publish at the user's own apex or subdomain
  • TLS issued and renewed forever, no manual cert work
  • One CNAME for the user to add — no second SSL record

How it works in 3 steps

  1. Your user types their hostname (acme.com) into your UI.
  2. your website builder 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": "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.
