Astro

Overview

Astro is an all-in-one web framework for building fast, content-focused websites. It uses an islands architecture that ships zero JavaScript by default, hydrating only interactive components on demand. Components from React, Svelte, Vue, Solid, and Preact can coexist in a single project.

When to use: Content-driven sites (blogs, docs, marketing), portfolios, e-commerce storefronts, any site where most pages are primarily static with isolated interactive regions.

When NOT to use: Highly interactive single-page applications (dashboards, real-time collaboration tools), apps requiring full client-side routing with shared global state across all components.
