I don't think you can have a serious Erlang alternative without an entire runtime, but if you are interested in the (better) C-style syntax, then you miht be interested in Gleam[1] which is a seriously cool Erlang based language that is built with standard styling and ideas (type-safe, concurrency (actor-based), C-style, immutable, you can even compile out to javascript and run in the browser)
Think Elixir, access to the entire Erlang VM (and any other language/package built on it) with the syntax of C and you are there.
I forgot about Gleam, it is definitely really interesting, but its also strange since I think you have to compile your code, I don't think you can just debug it as you write it.
