Astro

Astro is a web framework popularized for "Islands Architecture". It ships zero JavaScript to the client by default, hydrating only the interactive parts. Astro 5 (2025) introduces Server Islands.

When to Use

• Content Sites: Blogs, Documentation, Marketing sites.
• Multi-Framework: Use React, Vue, and Svelte components on the same page.
• Performance: Hard to beat for static content.
