What framework other than Next.js let's you use folder based routing?

My requirement is simple: - folder based routing like next.js. - route loaders for SSR - not a pain in the butt

What we tried: Remix/ React Router: - folder based routing doesn't work. /cheese/cake -> cheese.cake/route.tsx

Tanstack Start: - Too new. Don't have confidence yet.

We are currently on Next.js but app router doesn't have getServerSideProps and generally it's a big pain in the butt to build and deploy on our own infra.
