Ask HN: Easiest and cheapest full-stack frameworks that you love?

Lately I've been interested in the idea of overnight startup. Well, not quite literally but the idea is to make projects in just days instead of months. I've been looking at multiple BaaS solutions like firebase, supabase, appwrite, pocketbase and UI frameworks like svelte, next.js, solid.js and more. I wonder what could be the best option? Something that is cheap to host (preferably free initially) and super easy to manage (like pocketbase having a GUI for creating RDBMS).
