brewdo is a wrapper for Homebrew that sandboxes the installation process, giving you the following advantages:

  • Your user account loses the rights to /usr/local, making it much harder to accidentally break your Homebrew-installed software (or other /usr/local software!)

  • Software installations lose the rights to your home directory, meaning software will never partially install into your home directory

  • A clean way to share Homebrew admin rights among multiple users of the same system

brewdo uses Sudo, but not to run commands as root; rather, to run Homebrew under a dedicated sandbox user account.

brewdo grew out of the experiment in my blog post, Sandboxing Homebrew, and is developed at GitHub.
