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.
Gatsby is a React-based static site generator and the framework that popularized the Jamstack approach — compiling pages at build time and serving them as pre-rendered HTML for maximum performance and SEO. Gatsby's plugin ecosystem handles data sourcing from any CMS, API, or database, and its GraphQL data layer stitches it all together at build time. It's used heavily for e-commerce, marketing sites, and content-heavy blogs by teams who want React's component model with the SEO benefits of static HTML. Gatsby sites are identifiable through the gatsby-image and gatsby-focus-wrapper CSS classes, the __gatsby global JavaScript variable, and script chunks served from the /static/ directory. Gatsby's build artifacts produce optimized JavaScript chunks with content hashes in filenames, and the gatsby-config.js manifest is often referenced in build artifacts.
