What is Astro?

Editorial review
Astro builds content-focused websites with partial hydration that sends minimal JavaScript to browsers. Use any UI framework you like-React, Vue, Svelte-but only ship code for interactive components. Static sites are fully static with zero JS by default. Islands architecture means the whole page doesn't need to be a client-side app just because one widget needs interactivity. Content sites, documentation, and marketing pages built with Astro load dramatically faster than typical React sites while keeping the DX developers expect.

Astro FAQ

How does Astro improve website performance?

Astro improves website performance by sending minimal JavaScript to browsers, leveraging partial hydration. It builds content-focused websites that load dramatically faster than typical sites by only shipping code for interactive components.

Which UI frameworks can developers use with Astro?

Developers can use any UI framework they prefer with Astro, including React, Vue, and Svelte. Astro's design allows for flexibility, letting developers choose their preferred tools while still benefiting from its performance optimizations.

What kind of user or team benefits most from Astro?

Astro is best suited for teams and developers building content-focused websites such as blogs, documentation, and marketing pages. Its strengths lie in delivering excellent performance for sites where content is paramount.

How does Astro compare to Next.js for website development?

Astro is designed for content-focused sites with zero JavaScript by default, leading to faster load times, while Next.js is often used for more complex applications. Astro allows developers to use any UI framework, but it is less suitable for Single Page Applications compared to Next.js.

Does Astro include a free tier for developers?

When is Astro not the ideal choice for a project?

How does Astro handle JavaScript for interactive components?

Astro handles JavaScript for interactive components through partial hydration, meaning it only ships the necessary code for those specific interactive parts. This approach ensures that the majority of the page remains static and fast, even if a widget requires interactivity.
