The short answer is no. Next.js is an open-source project, so you can use it for free in any project, commercial or otherwise. There are no fees associated with using Next.js, and there are no license restrictions on what you can do with it.
However, there are some costs associated with using Next.js. If you plan on deploying your application to a cloud provider, you’ll need to pay for hosting and bandwidth. Additionally, you may need to pay for other services such as databases, authentication, and analytics, depending on your application’s needs.
In addition to the potential costs of hosting, you may also need to pay for certain features or services that you want to use with Next.js. For example, if you’re building a blog, you may want to pay for a content management system to manage your content. You may also need to pay for a module or plugin to add certain features to your application.
Finally, if you want to customize Next.js, you may need to pay for additional development resources. Hiring a developer to help you build your application can be expensive, so you may want to look into alternatives such as using a managed service, or using a freelance developer.
Overall, Next.js is a great framework for building web applications, and it doesn’t cost anything to use it. However, you may need to pay for hosting and other services, as well as for any customizations or additional features. It’s important to consider these costs when planning your budget for your application.
