Build your platform on Vercel. Give every customer their own experience, custom domain, and the infrastructure to grow.

Choosing an architecture

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

Build single-codebase platforms. One codebase, one deployment serves every tenant.

Tenants: Each tenant shares the same functionality, with its own content, branding, data, and configuration. Route customers through custom domains, wildcard subdomains, or URL paths to the same application.
Complexity: Lower
Best for: Content and branding differ, but functionality is the same: documentation sites, website builders, and SaaS dashboards.

Build multi-codebase platforms. One team per tenant, multiple codebases.

Tenants: Each tenant can run custom code with independent configuration and infrastructure. Manage tenant teams and codebases through the REST API or the Vercel SDK.
Complexity: Higher
Best for: Each tenant needs custom code or isolated infrastructure: AI coding platforms and user-generated apps.

What you can build

Teams run many kinds of platforms on Vercel:

OSS AI Platform Template

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).
