Astro

Web framework optimized for content-driven sites. Renders components on the server and sends lightweight HTML with zero JavaScript by default, improving page load performance. Uses an islands architecture so interactive UI components from React, Vue, Svelte, or Solid load only where needed.

Used by large enterprises and powers many of the fastest marketing sites and blogs. HTTP Archive data shows a higher share of Astro sites pass Core Web Vitals thresholds compared with Next.js, Nuxt, or Gatsby. Differentiator versus full-stack frameworks: minimal client-side JavaScript unless explicitly opted in.

Key capabilities:

• Islands architecture: mix framework components with zero-JS HTML pages
• Content Collections for Markdown and MDX with TypeScript type-safety and frontmatter validation
• Support for React, Vue, Preact, Svelte, Solid, and vanilla HTML
• Built-in image optimization, View Transitions API, file-based routing
• Adapters for static or server-side deployment across major hosting platforms

Well-suited for marketing sites, blogs, documentation, and e-commerce: teams get a simple HTML-first approach while reusing existing React or Vue components where interactivity is required. Integrates with headless CMSs and works with standard deployment targets.
