Personally I use asdf to manage my software on Macs. It too has also changed its design recently to become user-hostile (the command-line tool no longer prints the options for the commands, and it's full of bugs since a recent major version change).
For anyone looking to make an alternative to Homebrew: check out asdf's plugin system! It is insanely easy for anyone to make an asdf plugin, install it, use it. It's just a directory of plaintext files/scripts somewhere on the web. I made a couple plugins for unpackaged apps within like 30 minutes of learning how plugins worked. Very "unix philosophy" (in a good way)
(aside: I'm not a "Mac person" (forced to use one by work), so I know this is an unpopular opinion, but Macs feel worse to use than either Windows or Linux. At least Windows has WSL2 if you like command-lines (or PowerShell if you're into that). OTOH Macs ship with insanely outdated incompatible tools, and the 3rd-party options are annoying as hell. Why do technical people keep using Macs?)
