Next.js vs. React: A multi-factor comparison
React and Next.js are frameworks that complement each other. Next.js builds on top of React and enriches it with multiple features, whereas React provides a solid ground for optimizations. Moreover, Next.js wouldn’t be possible without React. Then, why compare them?
In fact, the comparison is more than legit because newcomers to web development or business owners often can’t understand why two frameworks that are so much alike exist.
And indeed, at first sight, they look very much alike: you can create websites with React and Next.js equally, have similar initialization commands, and have a component-based structure. Except that React is more popular than Next.js.
“If they are so similar, then why would I prefer Next.js to React, especially given that React is more widespread?” — you may ask.
To answer this question, we will outline the benefits of using Next.js in place of pure React and specify the cases when you’re good with React as it is.

What is React?
React works on the principle of dividing complex UI elements into small pieces known as components. By default, it dynamically renders components in the client-side React DOM (Document Object Model).
What’s more, for every DOM, React builds a virtual DOM — a lightweight DOM’s copy that’s fast to manipulate.
React is easy to learn and is popular among front-end developers for its customizability, even when handling complex user interfaces. It’s well-suited for businesses that manage a bulk of customer data that is updated frequently.
🌟 Popular examples of React-based platforms include Meta, Netflix, Uber, and Airbnb.
What is Create React App (CRA)?
Create-react-app is a tool in the React ecosystem that optimizes initial application setup — it minimizes the need for manual configuration.
The tool assists developers in quickly producing a basic project file structure and running it as a single-page application (SPA). It is helpful for novice developers who don’t want to get into the complexities of the application’s underlying dependencies and seasoned ones when starting a new website.
As a result, you get a basic frontend web app with a single command. It includes all dependencies required to run a basic React web page.
What is Next.js?
Next.js’s main feature, SSR, consists in rendering a web page on the server side and delivering the final HTML page to the client. This results in shorter load times and more SEO-friendliness than React alone.
Next.js is a good fit for building responsive eCommerce websites that stay fast even when their architecture becomes complex over time. Popular examples of Next.js-based platforms include Hulu, Docker, TikTok, Netflix, and Scale.

Concepts: a library, a framework, a meta-framework
There are ardent terminological debates about how to call React, a library or a framework. Let’s clear up the theory — it will help us explain what position Next.js occupies in the web development ecosystem.
Some people claim that React is a library. And indeed, React is called a library on the project’s official website. However, in reality, React is more than just a library — it’s a framework. It dictates how developers should do things, whereas a library is just a collection of functions.
The reason why React was initially called a library is historical. Back in 2011, the authors wanted to designate a boundary between their new product and older web development frameworks. They picked the word library and insisted it’s not a framework.
React wasn’t like any other frameworks of that time. These worked in the model-view-controller (MVC) paradigm and provided all three elements in it. Meanwhile, React provided only the view element, allowing for more flexibility. So, in a nutshell, calling React a library was a marketing hook.
But if React is a framework, then what’s Next.js? It’s a meta-framework!
A meta-framework is an entity that sits one level higher in the architectural hierarchy than a framework. In fact, a meta-framework combines multiple frameworks together to provide you with a ready-made solution for multiple challenges, in our case — the ones related to web development.
At the end of the day, how we call things isn’t that important. What’s important is functionality. So let’s outline the cases when you need Next.js and when React is an okay option.
When to go for React instead of Next.js?
While Next.js improves React’s project structure and adds functionality, sometimes you would still go for plain React instead of Next.js or another meta-framework. Why is that?
It’s simply because sometimes Next.js is an overkill. For instance, if your application is for internal use only, so you don’t care about SEO. Next.js is very much SEO-oriented, so it contains too much functionality you don’t need in this case!
Then, if your goal is to create interactive dashboards and always keep the data fresh, then you’re better off with React alone. The reason is that Next.js is server-rendered by default. You’ll spend loads of time disabling serverSideProps and finding a workaround.
A third scenario involves leaving the idea of using Next.js behind. It’s when your project is so specific that out-of-the-box solutions aren’t suitable for it, and you have to implement the needed functionalities yourself or use some specific libraries tailored to your kind's challenges.
It makes little sense to branch off Next.js’s core and customize it for yourself if there are too many of such customizations.
Last but not least, if you’re developing a proof-of-concept and have to deliver it quickly, you can postpone using a meta-framework for later stages.
📝 Remember, no framework or library is a jack of all trades. They all come with tradeoffs. Your requirements and resources will define your framework choice.
Pound for pound: Next.js vs React
Let’s compare Next.js and React head-to-head on multiple aspects of software development.
|Performance||Next.js-based websites are fast due to their pre-rendering functionality.||React-based websites are interactive and scalable due to their reusable components. React websites can be faster when built using CRA.|
|End-Product||Next.js is equipped to build a complete web application, i.e., front-end and back-end services.||React is used to build the UI layer of web applications.|
|Web-Page Rendering||Next.js supports server-side rendering (SSR), where web pages are rendered and sent to clients as HTML pages.||React supports client-side rendering (CSR), where web pages are rendered into HTML at the client’s end.|
|Learning Curve||Next.js has a slight learning curve initially. But it has extensive support to guide novice developers.||React is very easy to learn, where developers can learn the tool even during application development.|
|Community Size||Next.js is new in the market and supports a relatively smaller but active community.||React is one of the most popular front-end tools that supports a huge community of active users.|
|Talent Pool||Next.js developers are fewer in number but are expected to grow with the increasing adoption of the framework.||React is a developer favorite and has become a commonly adopted skill. React supports a broad talent pool.|
|Cost of Development||Next.js is a free, open-source framework that significantly lowers the cost of web application development.||React is a free, open-source library offering low-cost web application development similar to Next.js.|
|Documentation||Next.js supports detailed documentation for its users.||React is also a well-documented JS library.|
Next.js pros and cons
Developers and business owners can only decide which tool to choose only after weighing the advantages and disadvantages of using Next.js vs. plain React. Let’s discuss some pros and cons of Next.js below.
The three pre-rendering options Next.js offers, namely, static site generation (SSG), incremental static regeneration (ISR) and server-side rendering (SSR), make Next.js-based websites significantly faster than the ones based on plain React.
Next.js stands true to its goal of simplifying the development of a React application.
Less code, less load
Next.js is a great framework for new developers — they can easily create complex web applications with this meta-framework. It allows developers to create more while coding less.
Next.js simplifies the work with images with its ability to scale them to adapt to changing viewports using WebP format. There are a great many image optimizations — we just can’t discuss them all here!
Next.js is opinionated
No, not that much opinionated as Gatsby is! But still, if you prefer to have full control over your choices, go for React!
When to use Next.js
When you need a static website with a lot of marketing landing pages.
When fast page rendering is an essential requirement. Next.js can render pages on the server so even users with slow devices can access them faster.
If you want to increase organic traffic on your website, pick Next.js: it can significantly increase it and improve your SEO scores.
When not to use Next.js
When you’re already using some other meta-framework.
If you’re building a data-rich back-office.
If you’re building a proof-of-concept.
React pros and cons
A React component can be incorporated into multiple pages of an application. Any updates on these components are rendered across all pages.
React library can be easily extended for more functionalities, e.g., using React with other tools like Redux.
React is supported by a massive community of developers that actively communicate and make every new aspect easier to learn for all developers.
High growth rate
React improves through its short development cycles that constantly modify the development environment. It requires developers to update their skills with the changing environment constantly.
React is only responsible for creating an application’s view layer. For a complete application, developers must incorporate additional technologies such as a back-end framework.
The React documentation often fails to keep up with the changing development environment.
When to use React
When working for platforms that require web pages and accompanying mobile applications, React is a great choice as its code is compatible with mobiles (React Native).
When you’re building large websites requiring reusable components, React can speed up the process. E.g., social media websites.
When building websites that receive rapidly changing or real-time data, e.g., news websites.
When not to use React
When developing simple landing pages, you can work without React.
You should opt for static site creators when your website does not require frequent re-rendering of web pages or their components.
When your web page requires CSS animation, the inline styling of React can be restrictive.
React in the wild
In this React project, we worked closely with Varcroft & Bianco's tech team to create a seamless integration between their 3D product configurator and Shopify. We designed the UI with Figma and built it in React.
Users can design their own drawer inserts in the progressive web app and order it directly with Shopify, which has been integrated into the app through the Shopify API.
Next.js in the wild
We worked with URUS to build an interactive marketing site with Next.js. The site includes interactive SVG animations to support Headstart Dairy's storytelling when you scroll through the site.
Creating an animated site with large SVG files where almost every SVG has its own individual component would be nearly impossible to create with a legacy content management system such as WordPress. However, by using Jamstack and a modern frontend framework, we can make the site work seamlessly on all devices.
