What makes Astro fast?
An overview of the core features. Figures and benchmarks will be added with sources.
Islands architecture
Interactive components become isolated islands. The rest of the page stays static HTML.
Little JavaScript
Astro only ships JavaScript to the browser where it is genuinely needed, by default.
Content collections
Your content gets a schema that is checked at build time.
Server-first rendering
Pages are assembled into HTML on the server, with SSR where needed.
Integrations
React, Svelte, Vue and more can coexist for the interactive islands.
Image optimization
Astro optimizes images at build time for faster pages.
