Next.js vs React

This is the question most beginners ask. Short answer: React is the library, Next.js is the framework built around it. You are still writing React when you use Next.js.

The main differences

	React (with a tool like Vite)	Next.js
What it is	A UI library	A full framework using React
Routing	You add a router yourself	Built in, based on files and folders
Rendering	Mostly in the browser	Server, static, or browser — your choice
Data fetching	You choose your own approach	Built-in patterns for server data
Backend / APIs	Separate server needed	API route handlers included
SEO	Harder (content loads late)	Easier (HTML ready on the server)

When plain React is enough

If you are building a small widget, an internal tool, or something that lives inside another page and does not need search-engine visibility, plain React with Vite is simple and quick.

When to choose Next.js

You want good SEO and fast first loads
You need pages, layouts, and navigation out of the box
You want to fetch data on the server and keep secrets off the client
You want your frontend and simple backend endpoints in one project

Tip:You do not have to pick perfectly. Skills transfer both ways — the components you write are React either way.

Which Should You Choose?

Need	React Alone	Next.js
Build a UI widget / component library	✓ Enough	Overkill
Full website with multiple pages	Needs React Router	✓ Built-in routing
SEO-important public pages	❌ Client-only render	✓ Server rendering
Data fetching from a database	❌ Needs separate API	✓ Server Components

# React alone — you wire everything yourself
npm create react-app my-app   # creates CRA project
# Then manually add: routing, data fetching, SSR, image opt.

# Next.js — full framework, batteries included
npx create-next-app@latest my-app  # routing, SSR, images ready
# App Router auto-handles: layouts, server components, caching

Next.js Architecture Takeaway: Server Actions enable secure server-side mutations directly from form submits or custom event handlers without REST endpoints.
