In general, the Gatsby vs NextJS discussion begins down to a simple choice.

Gatsby is good for creating static websites with rare content changes, while NextJS is good for creating complicated sites with high server interaction. All the same, there are important differences between these two frameworks that confuse developers when choosing which one to use for reliable web development. Gatsby can make on both the client and server side. Because of its server-side processing capabilities, you can pre-render and fetch pages when users visit your website.

Gatsby

When choosing between NextJS and Gatsby, it's important to remember the benefits of both. Gatsby has a shorter learning curve than NextJS, making it ideal for small applications. NextJS is better suited for large-scale applications and is optimized for use with Vercel, a popular deployment platform.

Both frameworks are compatible with other tech stacks. Next and Gatsby are good choices for single and multi-person applications, and both frameworks are suitable for a variety of web apps. Both frameworks support server-side and client-side rendering which is useful for web apps. It mainly focuses on generating static HTML pages and enabling blazing-fast performance.

NextJS

It is an open-source JavaScript framework that is built on top of Node.js. Because HTML is directly produced through the server whenever a new request is received, server-side rendering lessens the load on web browsers. This framework is best for developing dynamic websites with solid server interaction or large-scale applications.

Above all, this framework allows you to easily customize and replace all of its components. 

GraphQL

The main difference between Gatsby and Next.JS is their relationship to GraphQL. Gatsby is built on top of GraphQL, so data retrieval is done via his GraphQL queries. For developers new to GraphQL, getting started with Gatsby can be a bit of a learning curve. He could use Gatsby without GraphQL if absolutely necessary, but GraphQL is the key foundation for Gatsby's drawing.

Community Support

NextJS and Gatsby both have strengths and weaknesses. Both frameworks have excellent community support. The NextJS community is one of the largest and contains regularly updated high-quality content. It is also available on numerous platforms. The Gatsby community, on the other hand, is relatively small and its resources are limited to chats, agencies, and various agency programs. Gatsby is great for small to medium sized projects. However, it can be slow and buggy if the app gets too big. Additionally, it can create large JSON files, which can lead to scalability issues. This makes Gatsby ideal for static websites and small applications.

Conclusion

In summary, NextJS and Gatsby are both great React frameworks for the enterprise. However, NextJS is a better choice for businesses that want to quickly create custom React apps without much coding. Gatsby, on the other hand, is for large enterprises with much more complex code bases. Ultimately, NextJS and Gatsby are great options for companies looking to build custom React apps quickly, but they aren't perfect for every company.
