Next.js is a flexible React framework that gives you building blocks to create fast web applications. 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. With 4.3M downloads per week, Next.js is used by 500K+ frontend developers and designers – and over 30% of the Cloud 100 build with Next.js and Vercel, the builders and maintainers of Next.js. Vercel’s frontend cloud gives developers the frameworks, workflows, and infrastructure to build a faster, more personalized web. Companies, teams, and individual developers using Vercel benefit from a fully-managed, highly-optimized experience that enables customers like Under Armour, Nintendo, The Washington Post, and Zapier to build delightful user experiences.
