What is next.js?

What it is

Next.js is a JavaScript framework for building web applications, distributed under the MIT license and described by its maintainers as "The React Framework." It extends the latest React features so that developers can build full-stack web applications, and it integrates Rust-based JavaScript tooling to produce fast builds. The project lives in the React and Node ecosystem, and its topic list places it among static site generators, server-rendering tools, hybrid and universal rendering approaches, and compiler-oriented front-end tooling. The repository is ten years old and has been pushed as recently as September 2026.

The concrete problem it solves is the gap between a React component tree and a deployable web application. React on its own supplies components for the browser, but it does not cover server rendering, static generation, routing conventions, or the build pipeline that turns source files into something a hosting provider can serve. Next.js supplies those pieces as one framework rather than as a set of separately assembled libraries. Its topics — static-site-generator, ssg, server-rendering, hybrid, universal — describe the range of rendering strategies it addresses in a single project, which is the reason it is frequently reached for when a team wants both prerendered marketing pages and dynamic application routes without running two separate codebases.

Key capabilities

  • Full-stack web application development built on top of React.
  • Static site generation, indicated by the ssg and static-site-generator topics.
  • Server rendering, indicated by the server-rendering topic.
  • Hybrid and universal rendering, allowing prerendered and server-rendered output within one project.
  • Rust-based JavaScript tooling used to produce fast builds.
  • Browser and Node as the two runtime targets named in the topic list.
  • Component-oriented development, consistent with the components and blog topics.

Who uses it and how

  • Teams building full-stack web applications, as described in the README's opening paragraph.
  • Organizations referenced in the README as "some of the world's largest companies."
  • Developers producing static or prerendered sites, per the static, ssg, and static-site-generator topics.
  • Blog and personal-site authors, per the blog topic and the Content & Publishing category.
  • Contributors to the open-source project itself, working through the good first issues list.
