React is a JavaScript library for building user interfaces. Next.js is a production-ready framework built on top of React. They aren't direct competitors—they operate at different levels of abstraction. This article breaks down the differences between Next.js and React across key criteria, weighing pros and cons to help you pick the right tool for your project.

## Next.js vs React: Key Differences, Which Is Better, and When to Use Each

React, from Meta since 2013, excels at UI components. Next.js, from Vercel since 2016, layers on server-side rendering (SSR), static site generation (SSG), routing, and optimizations. For SPAs or dashboards, React shines. For SEO-heavy sites or full-stack apps, Next.js pulls ahead. The choice hinges on your needs: SEO and scale favor Next.js; pure client-side flexibility suits React.

Next.js vs React: comparison of key characteristics

## What Is React? Definition, Features, and Ecosystem

React is a JavaScript library for user interfaces, launched by Meta in 2013. It focuses solely on the view layer—rendering components that respond to state changes. No built-in routing, data fetching, or server features. The ecosystem fills gaps: React Router for navigation, Zustand for state, Vite for builds. This modularity offers control but demands setup. React underpins Next.js; its components slot right in.
