Homebrew
Open-source, free package manager for Mac and Linux
...Often called “the missing package manager,” it provides tools and applications that are not included by default with the operating system. Homebrew installs packages into its own directory and safely symlinks them, keeping the system clean and organized. It uses simple commands like brew install to handle downloading, building, and updating software automatically. Under the hood, Homebrew is built on Git and Ruby, making it transparent, customizable, and easy to extend. It complements existing system tools and package managers, streamlining development and power-user workflows.
