VanityCert.com is a B2B SaaS platform that solves the "1-to-N Domain Problem" for multi-tenant applications. We provide an all-in-one, white-label solution that automates the complex, time-consuming process of managing custom domains and SSL certificates for your customers.
Our platform handles the entire SSL lifecycle from start to finish, including:
By integrating our platform, SaaS teams can offload a significant infrastructure burden and focus their valuable engineering resources on building core product features and innovation.
Domainee is a custom domains API that lets SaaS products offer white-label domains to their users in minutes instead of months - and even sell domains directly inside their app. Connecting a domain takes a single CNAME record, with SSL certificates, renewals, and DNS verification handled automatically, while the Buy-a-Domain API turns domain registration into one API call. The first 50 domains and 100 GB of bandwidth are free forever, with no credit card required.
One-CNAME setup with automatic SSL: End users add a single CNAME at their registrar, and Domainee issues and renews their certificate via Let's Encrypt on the first request โ no DNS validation back-and-forth.
Buy-a-Domain API: Let users search for and purchase a domain without ever leaving your app. One API call registers the domain with your end user as the legal owner, configures DNS, and connects it to your product โ at wholesale price plus a flat $1 fee, with your own markup on top.
Stripe-shaped REST API: POST /v1/domains creates a domain, returns the CNAME, and fires a domain.verified event over HMAC-signed webhooks the moment DNS lands. Bearer keys and idempotency keys included.
Full domain lifecycle endpoints: DNS, nameserver, and renewal management via API, so your users never have to log into a registrar.
Hosted MCP server for AI agents: Drop one config block into Claude, Cursor, or any AI agent and get 11 ready-made tools to list, create, and verify domains in plain English โ no code change.
Real free tier: 50 custom domains and 100 GB of bandwidth every month, free forever. The free quota stays free even after you scale past it.

Domainee.dev's answer:
I built Domainee because I was tired of seeing developers waste months building the same custom domain and SSL infrastructure for every new project. I wanted to create a "set it and forget it" solution that handles the complex plumbing of DNS and certificates through a single, clean API. Domainee was born to turn a major technical headache into a copy-paste task, allowing founders to focus on their core product instead of infrastructure.
