One of the most common questions we receive from clients starting new projects is: should we use React or Next.js? The answer involves understanding what each technology actually is, because the framing of the question itself reveals a common misconception. Next.js is not an alternative to React — it is a framework built on top of React. But the choice of whether to use plain React (with Vite) or React-with-Next.js has significant practical implications.
What React Alone Gives You
React is a UI library — it handles component rendering and state management and nothing else. When you build a pure React app (typically with Vite), you are in charge of routing, data fetching, server interaction, and deployment configuration. This gives maximum flexibility but requires more setup and architectural decisions.
Pure React (Vite SPA) is the right choice for: internal tools and dashboards that do not need SEO, highly interactive applications where the user is always logged in, and Electron or React Native applications.
What Next.js Adds
Next.js adds opinionated conventions on top of React: file-system-based routing, server-side rendering, static site generation, React Server Components, built-in API routes, automatic image and font optimisation, and a production-grade build pipeline. For 98% of public web applications, Next.js is the correct default. You get SEO, performance, and developer experience improvements without any meaningful drawbacks.
Performance: Server Components Change Everything
The App Router in Next.js 13+ introduced React Server Components, which render on the server and send zero JavaScript to the client. A typical product page built with Server Components has a JavaScript bundle 40-70% smaller than an equivalent SPA, leading to dramatically faster Time to Interactive scores. For any application where SEO and page speed matter, this single feature alone justifies Next.js.
When Should You NOT Use Next.js?
Next.js adds deployment constraints (you need a Node.js runtime or Vercel for full feature support), complexity compared to a pure static site, and a learning curve for developers unfamiliar with the SSR paradigm. If your application is a private tool with authenticated users only, or a statically-generated documentation site that rarely changes, pure React with Vite or a dedicated static site generator may be simpler.
— Conclusion
In 2026, choose Next.js for any public-facing web application. Its performance, SEO, and developer experience advantages over plain React are too significant to ignore.
