Astro public beta released

Fred Schott and contributors released Astro's first public beta on June 8, 2021 — a static site builder that ships zero JavaScript by default with partial hydration.

What it was for

Vite (software)Astro's island architecture lets developers use ReactA JavaScript library for building UIs — component trees and declarative rendering for the web., Vue, or Svelte components but only hydrate interactive islands — dramatically cutting page weight. It became the default choice for content-heavy sites prioritizing Core Web Vitals.

Why it's here

Astro pioneered partial hydration for content-focused sites.

Why it mattered

Ship less JavaScript became a mainstream performance strategy.

What it solved

Static site generators shipped entire framework runtimes even for mostly static pages.
