What is the difference between Next.js and React?
Updated 2 min read6 differences
In short
React is a library for building UIs from components, while Next.js is a React framework that adds routing, server-side rendering and static generation.
Next.js
Next.js is a React framework that adds routing, server-side rendering, static generation and server code, so a whole web app can be built as one project.

React is an open-source JavaScript library for building user interfaces from reusable components that update automatically when their data changes.

| Aspect | Next.js | React |
|---|---|---|
| Type | A full-stack framework | A UI library |
| Routing | File-based, built in | Not included; add a router library |
| Rendering | Server, static, client and streaming | Client-side by default |
| SEO | Strong, with HTML rendered on the server | Weaker for pages that need search traffic |
| Backend features | API routes, server actions, middleware | None; needs a separate backend |
| Hosting | Node.js servers or platforms like Vercel | Static files on any host |
The difference, explained
React handles the view: components, state and rendering. On its own it doesn't decide how URLs map to pages, how data is loaded, how the app is rendered on a server or how it is bundled for production. Next.js, first released in 2016 by the company now called Vercel, answers all of those questions with conventions, so you write React components inside a complete application framework.
In Next.js, folders in the app directory become routes, and each page can be rendered on the server per request, generated statically at build time, or a mix of both. React Server Components run on the server and send ready HTML, so less JavaScript reaches the browser, which helps load speed and SEO. API routes, middleware, image and font optimization are built in.
A plain React app, typically created with Vite, renders in the browser as a single-page application. That is simpler and works well for dashboards, internal tools and apps behind a login where search engines don't matter, and it can be hosted as static files anywhere.
A common misconception is that Next.js and React are competitors. Every Next.js app is a React app; the question is whether you want React alone and choose the rest yourself, or React inside a framework that makes those choices and adds server features.
Which one should you use?
Choose Next.js when…
- Search engines and fast first loads matter for your pages.
- You want routing, data loading and rendering decided for you.
- You want server code and front end in one project.
Choose React when…
- You build a dashboard or app behind a login where SEO doesn't matter.
- You want the simplest setup that can be hosted as static files.
- You prefer to choose your own router and data tools.
Readers ask
Do I need to learn React before Next.js?
Yes, at least the basics. Next.js pages are React components, so understanding components, props, state and hooks comes first.
Is Next.js only for server-side rendering?
No. It supports server rendering, static generation at build time and client-side rendering, and different pages can use different strategies.
Can I host Next.js somewhere other than Vercel?
Yes. Next.js runs on any Node.js server or container, and a static export can be hosted anywhere; some features need a server to work.
