Check out fly.io as well. They've been adding some SQLite stuff. They also have the added benefit that you can run just about any docker image, not just functions.
this indie-stack shows how to use the remix framework, fly.io, SQLite and Prisma together.

I think fly.io will only expand their SQLite features with the creator of Litestream onboard. Exciting stuff!
