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.
Astro is a modern web framework that pioneered the 'islands architecture' — shipping zero JavaScript by default and hydrating only the interactive components that need it, resulting in extremely fast initial page loads. Unlike traditional React or Vue frameworks, Astro components compile to pure HTML at build time, and interactive widgets (React, Vue, Svelte, or Solid components) are loaded as isolated islands when needed. It's the framework of choice for documentation sites, blogs, marketing pages, and any content-focused site where performance is paramount. Astro sites are identifiable through the astro-island custom element wrapping client-side interactive components, assets served from the _astro/ directory path with content-hash filenames, and the astro-island attribute in the DOM. The framework produces minimal JavaScript payloads, which makes Astro sites score exceptionally high on Core Web Vitals.
