Zerobrew looks mature, I'll check it out.

Btw, I noted this:

> Zerobrew is experimental. We recommend running it alongside Homebrew rather than as a replacement, and do not recommend purging homebrew and replacing it with zerobrew unless you are absolutely sure about the implications of doing so.

So I guess its fine to run this alongside Homebrew and they don't conflict.

And zerobrew, like the original Homebrew, is compatible with Linux.

It appears that Nanobrew is not.

I care about the light-weight efficiency of these new native code variants much more when I want to use brew on some little Linux container or VM or CI, than I do for my macOS development machine.
