CustomDomain (customdomain.ai, styled CustomDomain™) provides custom-domain onboarding for SaaS platforms whose customers bring their own domain: it detects the customer's DNS provider and auto-configures records across 25+ DNS hosts (or shows them), issues SSL automatically, and runs an edge proxy that serves the traffic. It offers a REST API with webhooks, a drop-in connect widget and SDK, and an MCP server so AI agents can connect domains, aimed at site builders, e-commerce platforms, creator tools and agencies.
