Create React App, Gatsby.js, and Next.js are frameworks for writing web applications in React.js. With so many ways to build React apps, it can be confusing to know which framework to choose for building your web app. In this article, I describe what each framework excels at and when you might choose one framework over another based on different circumstances.

Create React App

Create React App (CRA) is a script that quickly spins up a React project and lets you start coding right away.

The great thing about CRA is that it is dead simple to set up. There is basically no configuration to get up and running. This lets you focus on coding your app right away, instead of worrying about configuration files.

I would recommend using CRA for projects where SEO is not a requirement. If you view page source on an app built in CRA, you will see a <script> tag that links the React application, and that's about it. Web crawlers parse HTML to extract information about the web page, so if all it sees is that it loads some JavaScript, then the crawler does not get as much context about what your site is about, making it harder for your page to show up in search results.

Assuming SEO is not a priority, CRA is just so easy to get up and running and has a great developer experience, so it could be a great option. However, if you want to build a site that is easier for web crawlers to index your webpage, then you might want to look at either Gatsby or Next.


Gatsby.js is a static site generator for your React app. This means when a web crawler is looking at your website, it can see all the HTML produced by your React (JavaScript) code. With this, the crawler can better understand your webpage which can help your page rank higher in search results.

Gatsby also has a huge array of plugins that make a lot of things about making a website easy and convenient. For example, there are plugins for generating a sitemap, lazy-loading images, accessing the filesystem, and so much more. Gatsby also has a great community and ecosystem of people working to continuously improve it.

One of the core features of Gatsby is that it uses GraphQL to integrate Gatsby plugins and data-fetching. For example, if you are using the gatsby-image plugin, you would need to go through the GraphQL data layer to fetch example.jpg.

import { useStaticQuery, graphql } from 'gatsby';
import Img from 'gatsby-image';

// fetching hello.jpg from GraphQL data layer
export default function HelloImage() {
  const data = useStaticQuery(graphql`
    query {
      file(relativePath: { eq: "example.jpg" }) {
        childImageSharp {
          fluid(maxWidth: 500) {

  return <Img fluid={data.file.childImageSharp.fluid} alt="hello!" />;

I recommend using Gatsby when you need your site to be SEO friendly and performant. Gatsby's rich plugin ecosystem makes building fast sites easy. If the content on your site is static and can be updated at build-time, then Gatsby is a great choice.

If your app is more dynamic and requires dynamic data on each page request, then you may want to look at Next.js, which offers out of the box server-side rendering.


Next.js is a framework that lets you choose to statically generate or server-side render any web page of your site. With server-side rendering, your JavaScript code is hydrated on the fly, instead of at build time. This is great for dynamic pages like a logged-in user's news feed. In these situations, your app would need to fetch data unique to that user to serve personalized content on-demand.

For content that doesn't change often, like your marketing pages, documentation, etc, Next gives you the option to statically generate pages. There are performance benefits to statically generate pages compared to server-side rendering pages so having this option is quite nice.

With Next, you are getting the best of both worlds with statically generated pages as well as server-side rendered pages, making Next a great option for web apps.

Other options

If you need to customize the low-level configuration of your app, you may want to create your own toolchain using a tool like Webpack. I probably wouldn't recommend going this route if you're a smaller team and need to focus on building and shipping your product. Going this route will require you to spend more time figuring out your own solutions for static generation, server-side rendering, and turn-key configuration the frameworks provide you.

But if you have a large team of engineers and your app is operating at a scale that demands this customization, then going this route may be the best option.


  • Choose CRA for the easiest setup and development experience. A great option when SEO is not a priority.
  • Choose Gatsby if the content on your site is static and updates can happen at build time. Gatsby is a great option for blogs, documentation, and marking sites.
  • Choose Next if you want to build a web app with dynamic content. Next is a great option for apps with news feeds, analytics dashboards, and otherwise dynamic data.
