- Multi-Framework Support: Use React, Vue, Svelte, and Solid components in the same project.
- Markdown & MDX: First-class support for content-heavy sites.
- Fast by Default: Minimal JavaScript results in excellent performance scores.
Use Cases
Astro is perfect for blogs, portfolios, and documentation sites where content is king and performance is paramount.
