pkgsrc vs Growl

pkgin aims to be a tool similar to apt/yum for managing pkgsrc binaries by relying on pkg_summary for installing, removing and upgrading packages and dependencies, using a remote repo.

Has been adopted to be used on several Unix-like operating systems and Windows. It's also the default package manager of DragonflyBSD and of the (now discounted) Bluewall Linux distro.

Installs its own dependencies which means that it is very secure. Cannot install anything unless you use the "sudo" command which is in keeping with the Unix philosophy.

Fast software installation is possible by using binary packages. It's also easy to build from source which allows for different compile-time options (like different UI backends) as well as gaining access to pre-release versions of software in certain cases.

Backporting fixes can be done by cherry-picking updates from a newer branch (pkgsrc is released every 3 months) and creating a package. Sometimes bugs need to be fixed for production and there is neither a fix in newer pkgsrc nor the softwares upstream. So pkgsrc has tools like pkgdiff, mkpatches, etc. that help with developing patches and building binary packages from that. A bit of documentation about that process can be found here.

This means that you can install it fresh on a new installation of MacOS and have all your favorite apps installed right from the start.

Can be used from within Ansible to install packages on macOS.

This one works brilliantly.

In addition to all the applications that other people have written that support Growl, Growl includes several 'Extras' that serve various functions.

Growl comes with almost 20 themes pre-installed so you can pick what works best for you. You can also create and install your own custom themes.

Prowl is the Growl client for iOS. Push to your iOS device notifications from your Mac or Windows computer, or from a multitude of apps and services.
