Vercel now supports [Fastify](https://fastify.dev/) applications, a web framework highly focused on providing the best developer experience with the least overhead and a powerful plugin architecture, with zero-configuration.

**src/server.ts**
```typescript
import Fastify from 'fastify'

const fastify = Fastify({ logger: true })

fastify.get('/', async (request, reply) => {  return { hello: 'world' }})

fastify.listen({ port: 3000 })
```

Backends on Vercel use [Fluid compute](https://vercel.com/fluid) with [Active CPU pricing](https://vercel.com/blog/introducing-active-cpu-pricing-for-fluid-compute) by default. This means your Fastify app will automatically scale up and down based on traffic, and you only pay for what you use.

[Deploy Fastify on Vercel](https://vercel.com/templates/backend/fastify-on-vercel) or visit the [Fastify on Vercel documentation](https://vercel.com/docs/frameworks/backend/fastify)
