Right now, sveltekit + skeleton has absolutely blown my mind at how fast you can make a usable prototype. It’s honestly insane. You don’t even need to know svelte, really. As long as you can understand the file based routing thing, the rest is just html unless you really need more. Especially with the tailwind stuff built right in and a mostly vanilla looking theme.
I’ve tried probably a dozen different things in the last few months, ranging from Astro to Lit to NextJs to using the built in golang templating system, pug, eleventy, and more I’m forgetting. So far this is my favourite in just about every way.
