What is Next.js?

Next.js is a React framework for building production websites and web applications. It handles routing, server-side rendering, static generation, image optimization, and API endpoints out of the box — things you'd otherwise configure manually with raw React.

Think of React as the engine and Next.js as the car. React gives you components and state management. Next.js gives you the build system, deployment pipeline, and performance optimizations that make those components work in production.

Key features: file-based routing (create a file, get a URL), Server Components (run React on the server for better performance), ISR (update static pages without rebuilding), Image component (automatic optimization, lazy loading, format conversion), and API Routes (backend endpoints in the same project).

Next.js is the right choice for: marketing sites, e-commerce, blogs, SaaS landing pages, documentation, and any site where SEO matters. It's used by Netflix, TikTok, Notion, Twitch, and Nike.

Next.js is not ideal for: purely client-side applications (dashboards, admin panels) where SEO doesn't matter — Vite + React is simpler for those. It's also heavier than needed for a single-page landing page.

We build every Empirium project on Next.js. It's the best balance of developer experience, performance, and SEO capability available in 2026.
