Astro is _really_ great for static sites. It doesn't feel heavy like Gatsby and Hugo do. I understand what's going on and I get to write JSX that compiles to static HTML.

> What other technologies can be replaced by Astro, to have an example?

As I mentioned above, and you hit on this too, I think Astro can replace static site generators. It wouldn't replace React (or your favorite framework), but it would use those frameworks to reduce your overall reliance on JavaScript and let most of your site be static HTML.

Astro has "island" pattern which allows you to selectively use JS frameworks on portions of pages where interactivity is required. You can use React, Vue, Svelte, etc.

The big benefit of islands is that the majority of your site is static HTML and only the bits of each page that actually need JS rely on it vs React where your entire site would use JS.

I haven't used this feature but I have heard that people really like it.
