About Astro
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.
