I have a small homelab running a few services, some written by myself for small tasks - so the load is basically just me a few times a day.
Now, I’m a Java developer during the day, so I’m relatively productive with it and used some of these apps as learning opportunities (balls to my own wall overengineering to try out a new framework or something).
Problem is, each app uses something like 200mb of memory while doing next to nothing. That seems excessive. Native images dropped that to ~70mb, but that needs a bunch of resources to build.
So my question is, what is you go-to for such cases?
My current candidates are Python/FastAPI, Rust and Elixir, but I’m open for anything at this point - even if it’s just for learning new languages.

Python is very straightforward and doesn’t use much memory in general< 60MB. However, it depends greatly on the framework (same as other languages!), but for a simple REST service, FastAPI is a star. It models endpoints as functions. I don’t recommend using it for anything production though. There is also Flask, but I haven’t used it enough.
