Zero-Configuration Koa Deployment

Vercel has added native support for Koa applications, the expressive HTTP middleware framework popular for building web applications and APIs. Developers can now deploy Koa apps to Vercel without any custom configuration.

How It Works

Deploying a Koa application is straightforward. Simply write your Koa server using the framework's standard patterns and push to your repository—Vercel's platform automatically detects and deploys it:

import Koa from 'koa'
import { Router } from '@koa/router'

const app = new Koa()
const router = new Router()

router.get('/', (ctx) => {
  ctx.body = { message: 'Hello from Koa!' }
})

app.use(router.routes())
app.use(router.allowedMethods())
app.listen(3000)

Compute & Pricing

Koa applications on Vercel automatically run on Fluid compute with Active CPU pricing, meaning:

• Automatic scaling: Your app scales up and down based on incoming traffic
• Pay-per-use pricing: You only pay for the CPU time your Koa server actually uses
• No configuration needed: These features are enabled by default

Getting Started

For complete deployment details and best practices, consult the Koa on Vercel documentation. Deploy your first Koa app with a free Vercel account, or contact the sales team for Pro or Enterprise deployments.
