It needs world-writtable /opt/homebrew, so I guess a Linux equivalent would be Nix (which IIUC requires writable /nix).

For something that only uses your home folder, I recommend checking out mise https://mise.jdx.dev/

In multi-user mode, Nix uses dedicated build users to write to the store. There is also single-user mode, but that also doesn't require a world-writable store.

Or just homebrew on Linux?
