SvelteKit is a very complete and well designed solution. Routing, data loading, forms, SSR, caching, dealing with environment variables - all very nice. The only "drawback" is Svelte - I just don't like the data binding thing and prefer working with React components and hooks. Maybe that's just because I've spent so much time in React/Next. Well written React code is actually quite easy to debug, reason about and debug. I find it super annoying to refactor Svelte code because every time I want to extract some code into a component it can't be a function in the same file before it becomes a whole new file. It has to be a file. Also haven't found anything nearly as nice as Framer Motion and Radix in Svelte land.
