Oh hello there! I'm the founder of https://railway.app/ and "Vercel for Backends" is what we get a lot

You can give us a go at https://dev.new/

We're working on making the project connections a bit better so that generalizable connected services are as trivial to build as stateful monolithic backends in the current platform

Anything else we've missed and I'm happy to sit down with you (or anybody else) and hear what your needs are. Arbitrary evented triggers are coming pretty soon as well as the API so the infrastructure should be fully composable/meta.

P.S We integrate with the lovely lads/lasses/fiends at Vercel :)
