Next.js is a React framework that allows you to build static and server-rendered web applications. It is a popular choice for developers who want to build modern web applications with React.


Get started in no time with the Next.js template.


To deploy a Next.js application with Genezio, all you need to do is to run the following command in the root directory of your project:

genezio deploy

This command will build your Next.js application and deploy it to the cloud. Genezio uses a genezio.yaml file to store configuration about your project such as project name and region. When running the genezio deploy command, Genezio will create this file for you if it doesn't exist after asking you some interactive questions.

The genezio.yaml configuration file will look something like this:

# The name of your project, which also influences the subdomain of the project.
name: genezio-project
# Select a region closest to your user base for optimal performance.
region: us-east-1
# Specifies the version of the YAML configuration syntax being used.
yamlVersion: 2

Frequently Asked Questions

  • How do I set a custom subdomain for my Next.js application?

    The subdomain assigned for your deployed Next.js application is generated automatically by concatenating the name of your project with a random short string. For example, if your project is named my-nextjs-app, the subdomain will look like

    The subdomain can't be customized at the moment. However, you can set a custom domain for your Next.js application by following the instructions in the Custom Domains section.

  • How do I check the logs of a Next.js application?

    Your Next.js application is deployed on our Function as a Service platform as multiple serverless functions. When opening the project dashboard, you can see the logs of each function separately.

    Each Next.js project can use one or more serverless functions

    Usually, the main logic of your application is deployed in the serverless function named function-server. Check the logs of this function to see the output of your application.

  • How do I set environment variables for my Next.js application?

    Environment variables for a Next.js project hosted on Genezio are set in the same way as any other Genezio project. Visit the Environment Variables tab in the project dashboard to set your environment variables.

  • How do I test locally?

    We recommend using the provided Next.js scripts to run your application locally. You can use the following command to start your application:

    npm run dev
  • Do I need a Docker/Dockerfile?

    No, you don't need a Dockerfile to deploy a Next.js application with Genezio. Genezio builds your application using a serverless architecture, which means that you don't need to worry about Docker, Dockerfiles or scaling.

Known Limitations

Incremental Static Regeneration (ISR)

Incremental Static Regeneration (ISR) in Next.js allows per-page static generation and dynamic content updates. It revalidates pages on-demand, striking a balance between static and dynamic content.

At the moment, Genezio does not support incremental static regeneration (ISR) for Next.js applications. However, we are working on adding this feature in the future.

Building on Windows

At the moment Genezio does not support building Next.js applications on Windows. In case you are using Windows, we recommend using WSL (Windows Subsystem for Linux) to build your Next.js application with Genezio.

This limitation comes from the Open-Next library, which we use to build your application using a serverless architecture. We are working on adding support for Windows in the future.

There is an opened issue in the Open-Next repository that you can follow to get updates on this limitation:
