Most platforms on Vercel follow one of two patterns. Pick the one that matches how isolated each customer needs to be:

For a multi-tenant build, clone the Platforms Starter Kit. For a multi-project build, create and deploy tenant projects with the Vercel SDK.

Teams run many kinds of platforms on Vercel:

• Content platforms, such as Hashnode and Dub.
• Documentation platforms, such as Mintlify, Fern, and Plain.
• Website and store builders, such as Super, Typedream, and Universe.
• B2B SaaS platforms, such as Zapier, Instatus, and Cal.

A typical setup gives you a root domain for your platform (acme.com), subdomains for tenants (tenant1.acme.com), and fully custom domains for customers who want them (tenantcustomdomain.com).

• Unlimited custom domains and *.yourdomain.com subdomains.
• Automatic SSL. Vercel issues and renews certificates for every tenant domain.
• Programmatic domain management through the REST API or the Vercel SDK.
• Global low-latency routing over the Vercel CDN and Anycast network.
• Preview deployments so you can test tenant changes before they ship.
• Support for 35+ frontend and backend frameworks.
