What languages/frameworks for small, very low usage apps on limited hardware? (feddit.org)

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.

Languages

Frameworks

That said, Python and Rust are great for setting up "starting up" / "small task" apps and growing up from there.

There's nothing to really grow. It's mostly just small helpers. Aggregate sensor data, pull data from A and push it to B every hour, a small dashboard, etc.

C is too involved for my case , I want to be productive after all.

Rust is already rather low level, though there are some cool looking frameworks.

C is an extremely expressive language. There's a reason it won't die and, while we all love to shit on it for the memes, you can write perfectly safe software in it.

you can write perfectly safe software in it.

In the same way that you can safely walk through a minefield.

I dunno what you mean about it being an expressive language either. I would say it is relatively low on the expressiveness scale compared to something like Python or OCaml. It's basically as expensive as Go which is renowned for being unexpressive. Maybe you didn't mean "expressive".
