Astro

Astro is an open-source web framework for building content-driven websites — blogs, marketing sites, documentation portals, and headless WordPress frontends — with a focus on shipping zero JavaScript by default. Astro renders pages to static HTML at build time (or on demand at the edge) and only hydrates the small "islands" of interactivity that genuinely need client-side JavaScript, leaving the rest of the page as plain HTML. This makes Astro sites measurably faster than their React/Next.js equivalents on content pages where most of the surface is read-only. Astro supports components written in any major framework (React, Vue, Svelte, Solid, Preact) in the same project, which makes migration paths from existing stacks practical. In a headless WordPress context, Astro pairs with WPGraphQL to fetch posts at build time and ship them as static pages, achieving the editorial-team-uses-WordPress, visitors-get-static-HTML pattern that headless promises but Next.js often complicates with SSR overhead.
