Domain SDK

TypeScript SDK for adding and managing custom customer domains across platforms

From the Xiry library · Updated 10 October 2026

Visit github.com ↗

Domain SDK provides a unified TypeScript client to programmatically add, verify, monitor, and remove custom domains on hosting platforms like Vercel, Cloudflare, and Netlify. It normalizes DNS record generation, verification states, and TLS certificate tracking across different backends. This saves multi-tenant SaaS developers from writing bespoke domain-handling infrastructure.

What it's for

  • Add custom domain management to a multi-tenant SaaS platform
  • Generate accurate DNS records and instructions for customer onboarding
  • Track ownership verification and SSL certificate issuance asynchronously
  • Provision and manage tenant-specific subdomains under a root domain

Features

  • Adapters for Vercel, Cloudflare for SaaS, Railway, Render, Netlify, and bunny.net
  • DNS registrar adapters for Porkbun, Namecheap, and Spaceship
  • Normalized domain lifecycle tracking for routing, ownership, and TLS readiness
  • Sequential polling with retry logic, timeouts, and provider backoff
  • Tenant subdomain scoping with reserved label filtering
  • Isolated in-memory testing adapter that runs without hitting live APIs
