I've been playing with Astro lately. I'm a fan of it. It's made to static render content, but allows you to have server renders if you select an adapter. Everything renders statically by default which is nice because my routes are super quick. The routes that need to be dynamic can be flagged that way with one line of code.
I really like that it's compatible with pretty much every major frontend framework (including Svelte! 🎉). It also supports Markdown/MDX. I'm currently using it to render this blog on https://nandi-moon-52.deno.dev/blog
