Speed and zero JS
Astro ships no JavaScript by default. Pages load as static HTML, so the LCP stays low.
Why Astro
What makes Astro fast?
An overview of the core features. Figures and benchmarks will be added with sources, we make nothing up.
Content-first
Markdown, MDX and content collections are central. Writing feels like blogging, not programming.
Islands architecture
Only the interactive islands on a page become dynamic. The rest stays static and fast.
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.
SEO and findability
Clean, semantic HTML and fast load times help search engines and AI search.
