React is a JavaScript library for building user interfaces with component-based architecture, while Next.js is a full-stack framework built on React that adds server-side rendering, static generation, and built-in routing. Next.js provides more out-of-the-box features for production applications, whereas React offers greater flexibility for custom implementations.
React vs Next.js — Side-by-side comparison on A Versus B
Choose React if you're building interactive dashboards, single-page applications (SPAs), or need maximum flexibility and simplicity for frontend-only projects. Choose Next.js if you're building production-grade web applications that require SEO optimization, server-side rendering, API routes, or static site generation capabilities.

React vs Next.js — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for React vs Next.js.
Yes, absolutely. React is a standalone library that works perfectly for building standalone applications. You only use Next.js if you need its specific features like SSR, static generation, file-based routing, or API routes. Many production applications use React alone with external libraries for routing and state management.
Is Next.js just React with extra features?
Essentially yes. Next.js is built on top of React and adds a framework layer with server-side capabilities, routing, image optimization, and deployment tools. You still write React components in Next.js, but you get production-ready features out of the box. Think of it as 'opinionated React for full-stack development.'
Learn React first. React is the foundation—understanding components, state, and JSX is essential before learning Next.js. Next.js builds on React knowledge, so mastering React makes learning Next.js much easier (typically 2-4 weeks vs. 4-8 weeks for React).
Yes, migration is straightforward because Next.js is built on React. Your existing React components will work in Next.js. The main additions are adopting file-based routing and utilizing server-side features. Most projects take 2-6 weeks to fully migrate depending on complexity and library dependencies.
What's the performance difference in real applications?
Next.js with SSR/SSG typically delivers 60-70% faster initial page loads compared to React CSR applications. For a typical e-commerce site, React CSR averages 4-5 seconds to interactive, while Next.js SSG averages 0.8-1.2 seconds. The difference is most noticeable on slower networks and mobile devices.
