'''Next.js''' is an [[open-source]] [[Web framework|web development framework]] created by the private company [[Vercel]] providing [[React (JavaScript librarysoftware)|React]]-based web applications with [[server-side rendering]] and [[static rendering]].
React documentation mentions Next.js among "Recommended Toolchains" advising it to developers when "building a server-rendered website with Node.js".<ref name="React documentation">{{cite web |title=Recommended Toolchains |url=https://reactjs.org/docs/create-a-new-react-app.html#recommended-toolchains |access-date=10 July 2021 |website=React documentation |language=en-US |format=HTML}}</ref> Where traditional React apps can only render their content in the client-side browser, Next.js extends this functionality to include applications rendered on the server-side.
