What types of websites is Astro best suited for?

Astro is designed for content-rich websites like blogs, documentation sites, portfolios, marketing pages, and e-commerce storefronts where performance and minimal JavaScript footprint are priorities.

Can I use multiple UI frameworks in the same Astro project?

Yes, Astro supports React, Vue, Svelte, and Solid UI frameworks simultaneously within the same project, allowing you to mix and match frameworks based on specific component requirements.

When should I avoid using Astro?

Avoid Astro for highly interactive single-page applications where most of the page requires client-side state management and hydration, or when your project requires a single, tightly integrated framework ecosystem rather than multi-framework flexibility.
