What is Astro?

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.

Is Astro worth the price?

Great value

Astro is completely free and open-source under the MIT license.

There is no paid tier for the framework itself. Astro Studio (hosted database) existed briefly but has been deprecated in favor of third-party solutions like Turso.

Your only costs are hosting, which you choose independently (Vercel, Netlify, Cloudflare Pages, all with generous free tiers).

Hidden Costs & Gotchas

Hosting is separate, but free tiers from Vercel/Netlify/Cloudflare cover most sites

Server-side rendering requires a Node.js host (adds cost vs static hosting)

Astro DB/Studio was deprecated, database needs solved separately via Turso, Supabase, etc.

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

When is Astro not the ideal choice for a project?
