Homebrew
Homebrew is an open package manager distributing compilers, libraries, CLIs, and desktop apps through formulae and casks.
Why use it
Teams can reproduce part of a development environment with Brewfiles and automate common build dependencies.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Rolling updates change versions; audit bottles and third-party taps, and do not treat it as full environment locking.
