Platform Overviews
Next.js
Next.js is the world's most popular React framework for production web applications, created and maintained by Vercel — powering the frontends of companies like Vercel, TikTok, Twitch, and Hulu. It supports multiple rendering strategies: static site generation (SSG), server-side rendering (SSR), incremental static regeneration (ISR), and client-side rendering — often mixing strategies across different pages within a single application. Next.js is the default choice for new React projects requiring SEO, performance, and full-stack capabilities through its API Routes and Server Components. Next.js apps are identifiable through /_next/static/ paths for all compiled JavaScript and CSS chunks, the __NEXT_DATA__ JSON embedded in every page's HTML containing initial props, x-powered-by: Next.js HTTP headers on most deployments, and the Next.js chunk naming convention for split JavaScript files.
