subdomain.to is a cloud computing platform that lets SaaS companies offer custom, customer-owned domains without building or operating the underlying DNS, certificate, and routing infrastructure. The platform packages the complex operational burden of custom domain management behind a single integration, making it ideal for startups, engineers, and product managers looking to boost productivity. To use the service, you simply create an HTTPS destination and add each customer domain through the API or dashboard. subdomain.to then returns the exact DNS record to configure, monitors verification, issues the TLS certificate, and activates secure routing. Your application retains the original host information for tenant resolution throughout the process. Key features include automated DNS verification with a guided customer setup widget, managed TLS certificate issuance and renewals, and secure HTTPS routing. Developers can easily manage the entire lifecycle using SDKs, status APIs, and signed webhooks to track every stage of the domain setup.
