Next. JS

Next.js is an open-source development framework built on top of Node.js enabling React based web applications functionalities such as server-side rendering and generating static websites. React documentation mentions Next.js among "Recommended Toolchains" advising it to developers as a solution when "building a server-rendered website with Node.js". Traditional React apps render all their content in the client-side browser, Next.js is used to extend this functionality to include applications rendered on the server side.

The copyright and trademarks for Next.js are owned by company Vercel (previously named ZEIT), which also maintains and leads its open-source development.

As of March 2020, the framework is used by many large websites, including Netflix, GitHub, Uber, Ticketmaster, and Starbucks. In early 2020, it was announced that Vercel had secured twenty-one million dollars in Series A funding to support improvements to the software.
