Build fast content sites with less JavaScript
Astro builds content-focused websites with partial hydration that sends minimal JavaScript to browsers. Use any UI framework you like-React, Vue, Svelte-but only ship code for interactive components. Static sites are fully static with zero JS by default. Islands architecture means the whole page doesn't need to be a client-side app just because one widget needs interactivity. Content sites, documentation, and marketing pages built with Astro load dramatically faster than typical React sites while keeping the DX developers expect.
