Introduction

Domain SDK handles the custom-domain lifecycle across Vercel, Cloudflare for SaaS, Railway, Render, and Netlify. Add a hostname, show your customer the exact DNS records, and track provider state until the domain is ready.

import { createDomainClient } from "@opencoredev/domain-sdk";
import { vercel } from "@opencoredev/domain-sdk/vercel";

export const domains = createDomainClient({
  provider: vercel({
    token: process.env.VERCEL_TOKEN!,
    projectId: process.env.VERCEL_PROJECT_ID!,
  }),
});

Use Domain SDK when your SaaS needs to show exact DNS instructions, track provider-authoritative status, and keep provider-specific APIs out of the rest of your application. It does not register domains, host DNS, deploy apps, proxy traffic, or store tenant data.
