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.
