What is Next.js?

Next.js is the most popular React framework. Learn about SSR, SSG, and the App Router.

Next.js is a React framework that adds server-side rendering (SSR), static site generation (SSG), API routes, file-based routing, and image optimization on top of React. Toolular itself is built with Next.js using static export — every page is pre-rendered at build time into static HTML files that load instantly. Next.js eliminates the need to configure webpack, routing, code splitting, and SEO metadata manually, letting you focus on building your application.
