I spent a small amount of time looking into Astro and I didn’t get the difference with the Fresh framework created by the Deno team.. ? Fresh does this Island architecture already, and benchmarks on Astro website dont include Deno+Fresh to compare. So I’m still wondering what’s the benefit of using Deno+Astro vs. Deno+Fresh
My understanding is that Astro is able to more-or-less take a component from any combo of popular frameworks and render it, whereas Fresh is currently limited to just Preact via Deno. I think the limitation is to optimize for not needing a build step, and not having to tweak the frameworks themselves like Astro does (did?).
I'm not affiliated; I've just looked at both tools before.
