Astro

Astro is a web framework engineered for content-driven websites, utilizing a unique islands architecture to deliver zero-client-side JavaScript by default.

Astro optimizes performance by shifting the heavy lifting to the server. Its core feature, Astro Islands, allows developers to build interactive UI components using React, Vue, or Svelte while only shipping the necessary JavaScript to the browser. This approach results in faster Time to Interactive (TTI) and superior SEO outcomes for sites like The Guardian and Nordstrom. Version 4.0 introduced the Dev Toolbar and enhanced View Transitions, further streamlining the developer experience for high-traffic documentation and marketing platforms.
