What is Homebrew?
Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple's macOS operating system and Linux. Originally written by Max Howell, the package manager has gained popularity in the Ruby on Rails community and earned praise for its extensibility.
Homebrew has been recommended for its ease of use as well as its integration into the command line. Homebrew is a non-profit project member of the Software Freedom Conservancy and is run entirely by unpaid volunteers.
Homebrew has made extensive use of GitHub to expand the support of several packages through user contributions. In 2010, Homebrew was the third-most-forked repository on GitHub. In 2012, Homebrew had the largest number of new contributors on GitHub. In 2013, Homebrew had both the largest number of contributors and issues closed of any project on GitHub.
Homebrew has spawned several sub-projects such as Linuxbrew, which is a Linux port, Homebrew Cask, which builds upon Homebrew and focuses on the installation of GUI applications, and "taps" dedicated to specific areas or programming languages like PHP.
