Multi Zones


A zone is a single deployment of a Next.js app. You can have multiple zones and merge them as a single app.

For example, let's say you have the following apps:

  • An app for serving /blog/**
  • Another app for serving all other pages

With multi zones support, you can merge both these apps into a single one allowing your customers to browse it using a single URL, but you can develop and deploy both apps independently.

How to define a zone

There are no zone related APIs. You only need to do the following:

  • Make sure to keep only the pages you need in your app, meaning that an app can't have pages from another app, if app A has /blog then app B shouldn't have it too.
  • Make sure to configure a basePath to avoid conflicts with pages and static files.

How to merge zones

You can merge zones using Rewrites in one of the apps or any HTTP proxy.

For Vercel, you can use a monorepo to deploy both apps. Check the Monorepos blog post for more details on how it works and our with-zones example for a detailed guide using multiple Next.js applications.
