subdomain.to

Connect customer-owned domains to your SaaS with automated DNS verification, TLS certificates, and HTTPS routing.

subdomain.to is a custom domain infrastructure platform built for SaaS companies that need to offer branded domains to their customers without managing the underlying complexity themselves. Designed for product teams, platform operators, and developers, it handles the full lifecycle from DNS verification through TLS certificate provisioning to live HTTPS routing, all exposed through a single API endpoint that works across any stack. Teams connect a customer-owned domain, display one DNS record to the end user, and subdomain.to takes care of certificate management, strict hostname routing, and operational visibility from that point forward.
