Build platforms that serve multiple customers from a single codebase. Each customer gets its own domain or subdomain, while you keep one deployment, one set of branding, and one place to ship updates.
Most platforms on Vercel follow one of two patterns. Pick the one that matches how isolated each customer needs to be:
| Approach | Codebase and deployment | Complexity | Best for |
|---|---|---|---|
| Multi-tenant | One codebase, one deployment serves every tenant | Lower | Content and branding differ, but functionality is the same (documentation sites, website builders, SaaS dashboards) |
| Multi-project | One project and deployment per tenant | Higher | Each tenant needs custom code or isolated infrastructure (AI coding platforms, user-generated apps) |
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.comsubdomains. - 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.
