means Software you brew yourself at home rather than buy ready-made — originally beer and computers alike, now mostly a package manager that fetches and builds open-source tools on your Mac.

from The word is just 'home' plus 'brew', straightforward as a kitchen recipe — someone brewing beer in their own kitchen rather than buying it from a brewery. It got borrowed early into computing slang for homemade, unofficial hardware and software (the legendary Homebrew Computer Club of 1970s Silicon Valley, tinkerers building their own machines). The Mac package manager Homebrew picked up that same DIY spirit in its name: instead of a shop-bought binary, it hands you the ingredients and lets your machine do the brewing.
