Custom domains.
Zero support tickets.
The embedded infrastructure for B2B SaaS. Provide your tenants with domain search, automated DNS polling, and zero-config SSL certificates via a single, idempotent API.
The complete domain toolkit.
Drop-in embedded setup
A fully-styled, framework-agnostic UI component. Paste one script tag, and your users can connect, verify, and debug their domains without leaving your app.
Native purchasing
Allow users to search and register new custom domains right from your checkout flow.
CNAME & ALIAS
Full support for root domains and subdomains automatically routed to your edge.
Automated DNS Polling
Stop asking users "Did you configure your DNS?". Our engine polls nameservers globally and fires a webhook the millisecond records propagate.
Zero-config SSL
Automatic generation and infinite renewal of Let's Encrypt certs.
Designed by engineers, for engineers.
No obscure errors, no fragile workflows. The NomenKit REST API provides idempotent endpoints, highly predictable JSON responses, and webhooks for every state change in the domain lifecycle.
Idempotency built in
Safely retry requests without creating duplicate domains.
Granular webhooks
Listen to domain.verified and ssl.issued.
curl -X POST https://api.nomenkit.app/v1/domains \
-H "Authorization: Bearer nk_live_xxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"hostname": "store.acme.com",
"tenant_id": "tnt_893xjs",
"target": "cname.yoursaas.com"
}'{
"id": "dom_k39f8jd9",

},

}

}The automated pipeline.
Intent
User inputs target domain via embed or API. System validates format and registrar info.
Instructions
NomenKit generates tenant-specific CNAME, A, or TXT records required for verification.
Poll & Verify
System continuously polls global DNS networks. Triggers webhook immediately upon propagation.
SSL & Route
Certificate is automatically requested, issued, and attached to the edge. Traffic flows securely.
Scale without surprises.
Billed purely on active connected domains. Failed verifications and API lookups are free.
