Custom domains for SaaS, without the infrastructure

subdomain.to is a cloud computing platform that lets SaaS companies offer custom, customer-owned domains without operating the complex DNS, certificate, and routing infrastructure themselves. Instead of forcing engineering teams to build and maintain custom domain systems, this platform packages the entire operational burden into a single integration. It is designed for startups, product managers, and engineers who want to boost productivity by outsourcing the hassle of custom domain management. The platform works by automating DNS verification and managing the entire lifecycle of TLS certificate issuance and renewals. Once you create an HTTPS destination and add a customer domain via the API or dashboard, the service returns the exact DNS record needed, monitors its status, and activates secure HTTPS routing. Your application retains the original host information for tenant resolution, while status APIs and signed webhooks keep you updated on every lifecycle stage.
