What is Domainee?
Domainee is a custom domains API for SaaS teams whose users want to bring or buy their own domain. Your backend calls POST /v1/domains with a hostname and origin, Domainee returns a CNAME, then handles SSL, renewals, DNS monitoring, and state change webhooks. It also has a Buy a Domain API, MCP server support, and a free tier with 50 hostnames and 100 GB of monthly bandwidth.
Why Domainee works
Custom domains look small until the first certificate renewal fails, a customer points DNS at the wrong host, or an engineer ends up owning edge TLS forever. Domainee turns the moving parts into one API call, one customer CNAME, and webhooks when DNS changes, so a SaaS team ships custom domains instead of building a certificate and routing system.
Domainee features
- Bring your own domain flow. The Connect API returns a CNAME for a customer hostname, then handles SSL issuance, renewal, DNS health checks, and drift webhooks.
- Buy a domain inside your app. The Buy a Domain API lets users purchase from 500 plus TLDs, register as the legal owner, and connect the domain to your app with autoConnect.
- Automatic SSL and renewal. Domainee handles ACME challenges, certificate issuance, TLS termination, and renewal so your team does not manage Let's Encrypt plumbing.
- DNS state webhooks. Continuous DNS monitoring fires webhooks on state changes and surfaces issues such as a wrong CNAME, unresolved DNS, or Cloudflare proxy being enabled.
- REST and MCP access. The same Bearer key works for REST calls and the hosted MCP server, so Claude, Cursor, and Claude Code can list, create, verify, and debug domains.
- Published usage pricing. The first 50 domains and 100 GB of bandwidth are free. After that, domains start at $0.20 per month with volume discounts down to $0.10.
Who Domainee is for
- SaaS founders whose customers keep asking to use their own domains, but who do not want to spend months on edge TLS and DNS support.
- Engineering teams at scaleups managing 50 to 5,000 customer hostnames where custom domain upkeep is already becoming an owned system.
- Agencies and platform builders running client workspaces that need repeatable custom domain setup without a new registrar process each time.
- AI first builders working in Claude or Cursor who want their coding agent to provision domains and debug customer DNS from the same workflow.
Similar micro SaaS ideas you can build
- Enterprise SSO API. An infrastructure API that lets SaaS products onboard enterprise identity providers through a single integration. Connect Okta, Entra ID, Google Workspace, and other SAML/OIDC providers while the platform handles metadata exchange, certificate rotation, provisioning, and status monitoring.
- Webhook Infrastructure API. An API for software teams that need reliable event delivery. It handles retries, signatures, endpoint verification, replay, observability, rate limiting, and failure recovery so developers can ship webhooks without building delivery infrastructure from scratch.
- Email Deliverability Infrastructure API. An API that continuously monitors SPF, DKIM, DMARC, MX, and DNS health for domains. It detects configuration issues, tracks deliverability risks, and sends alerts or webhooks when changes threaten email delivery.
