Nix is centered around the local Nix store and binary caching.

As long as the specific version of Erlang you’re using is present in either your Nix store or the global cache for your OS and arch (at cache.nixos.org), you should not need to compile anything.

And if you rely on custom builds, you can just setup your own binary cache. This is similar to remote caching in Bazel.
