About Domainee

What is Domainee?

Domainee is a custom domains API that lets SaaS products offer white-label custom domains to their users. Instead of building and maintaining the infrastructure to issue SSL certificates, monitor DNS, and handle renewals, developers make one API call and Domainee manages the rest – forever.

Who is it for?

Ideal for engineering teams at scaleups (50–5,000 hostnames), solo founders, agencies building multi-tenant SaaS, and AI-native builders using Cursor or Claude Code. If your users keep asking for custom domains, Domainee solves that quickly. Not designed for small projects under 50 domains needing no automation, or for enterprises managing tens of thousands of hostnames (though volume discounts exist).

Use cases

Connect your user's existing domain via a CNAME (bring-your-own). Or let them buy a domain directly in your app – Domainee handles the registrar and SSL. One API key, one webhook handler, one workspace – works for per-client workspaces or multiple SaaS products.

Key features

  • REST API + MCP server – Provision domains with one POST /v1/domains endpoint, or let AI agents drive it.
  • Automatic SSL issuance & renewal – Let’s Encrypt SSL, auto-renewed forever, no manual steps.
  • DNS health checks & drift webhooks – Monitor DNS state changes and get alerted on misconfigurations.
  • Apex + subdomain support – Handle both root domains and subdomains with ease.
  • 50 custom domains free forever – Start without a credit card, scale when ready.
  • Webhook notifications – Real-time updates on domain status for your app's backend.
