## What it is
Astro is a TypeScript-based web framework for building content-driven websites with a powerful developer experience and lightweight output. It ships zero JavaScript by default and supports islands architecture for selectively hydrating interactive components from frameworks like React, Preact, Svelte, and Vue.

## Use cases
- build a fast marketing site or landing page
- create a developer blog with markdown and MDX
- generate a documentation site
- build a content-heavy site that ships minimal JavaScript
- add interactive React or Svelte islands to an otherwise static site
- build a hybrid site with server-rendered endpoints
- migrate a blog from Gatsby or Jekyll

## When to choose
- your site is mostly content like blogs, docs, marketing pages, or portfolios
- you want fast page loads with little or no client-side JavaScript
- you want to mix UI framework components into a static site
- you want built-in markdown/MDX and content collections support

## When to avoid
- you are building a highly interactive single-page application with heavy client state
- you need a full backend application framework with complex server-side logic
- your team depends on a single UI framework for the entire app
