I've been looking for exactly that: a backend thing that's as easy to setup as Netlify is for the frontend.

Micro seems to be a Go framework evolved to automatically deploy code to the "cloud", but it seems it'll remain limited to Go backends... I can write Go without problems, but I wanted something that supports other languages as well, specially Java... I think RedHat seems to offer that with OpenShift and Quarkus[1], but their material is so ridden with marketing buzzwords I am not sure it's suitable for what I'm looking for (basically, a small server that can store a small amount of documents or key-value information on whatever database the platform supports without fuss).

Heroku seems to be the most close to this I could find, but it's pretty expensive from what I saw if you need a DB.

Does anyone have suggestions for alternatives?
