What is a multi-tenant application?

Multi-tenant applications serve multiple customers across different subdomains/custom domains with a single unified codebase.

For example, our demo is a multi-tenant application:

Subdomain: demo.vercel.pub
Custom domain: platformize.co (maps to demo.vercel.pub)
Build your own: app.vercel.pub

Another example is Hashnode, a popular blogging platform. Each writer has their own unique .hashnode.dev subdomain for their blog:

Users can also map custom domains to their .hashnode.dev subdomain:

akoskm.com → akoskm.hashnode.dev

With the Platforms Starter Kit, you can offer unlimited custom domains at no extra cost to your customers as a premium feature, without having to worry about custom nameservers or configuring SSL certificates.

Examples of platforms

Vercel customers like Hashnode, Super, and Cal.com are building scalable platforms on top of Vercel and Next.js. There are multiple types of platforms you can build with this starter kit:

1. Content creation platforms

These are content-heavy platforms (blogs) with simple, standardized page layouts and route structure.

“With Vercel, we spend less time managing our infrastructure and more time delivering value to our users.” — Sandeep Panda, Co-founder, Hashnode

2. Website & e-commerce store builders

No-code site builders with customizable pages.

By using Next.js and Vercel, Super has fast, globally distributed websites with a no-code editor (Notion). Their customers get all the benefits of Next.js (like Image Optimization) without touching any code.

3. B2B2C platforms

Multi-tenant authentication, login, and access controls.

With Vercel and Next.js, platforms like Instatus are able to create status pages that are 10x faster than competitors.

Built on open source

This working demo site was built using the Platforms Starter Kit and:

Next.js as the React framework
Tailwind for CSS styling
Prisma as the ORM for database access
Novel for the WYSIWYG editor
Vercel Postgres for the database
Vercel Blob for image uploads
NextAuth.js for authentication
Tremor for charts
Vercel for deployment
