pkgsrc
pkgsrc is a framework for managing third-party software on UNIX-like systems, currently containing over 17,900 packages. It is the default package manager of NetBSD and SmartOS and can be used to enable freely available software to be built easily on a large number of other UNIX-like platforms. The binary packages that are produced by pkgsrc can be used without having to compile anything from the source. It can be easily used to complement the software on an existing system. pkgsrc is very versatile and configurable, supporting building packages for an arbitrary installation prefix, allowing multiple branches to coexist on one machine, a build options framework, and a compiler transformation framework, among other advanced features. Unprivileged use and installation are also supported. NetBSD already contains the necessary tools for using pkgsrc; on other platforms, you need to bootstrap pkgsrc to get the package management tools installed.

Rudix
Rudix is a build system target on macOS (formerly known as Mac OS X) with minor support to OpenBSD, FreeBSD, NetBSD, and Linux. The build system (also called "ports") provides step-by-step instructions for building third-party software, entirely from source code. Rudix provides more than a pure ports framework, it comes with packages, and precompiled software bundled up in a nice format (files *.pkg) for easy installation on your Mac. If you want to collaborate on the project, visit us at GitHub/rudix-mac or at our mirror at GitLab/rudix. Use the GitHub issue tracker to submit bugs or request features. Similar projects or alternatives to Rudix are Fink, MacPorts, pkgsrc, and Homebrew. Packages are compiled and tested on macOS Big Sur (Version 11, Intel only!), Catalina (Version 10.15) and OS X El Capitan (Version 10.11). Every package is self-contained and has everything it needs to work. The binaries, libraries, and documentation will be installed under /usr/local/.

NuGet
NuGet is the package manager for .NET. The NuGet client tools provide the ability to produce and consume packages. The NuGet Gallery is the central package repository used by all package authors and consumers. New to NuGet? Start with a walkthrough showing how NuGet powers your .NET development. Browse the thousands of packages that developers like you have created and shared with the .NET community. Want to make your first NuGet package and share it with the community? Start with our walkthrough! The command-line tool, nuget.exe, builds and runs under Mono 3.2+ and can create packages in Mono. Although nuget.exe works fully on Windows, there are known issues with Linux and OS X. The primary source for learning about a package is its listing page on NuGet (or another private feed). Each package page on NuGet includes a description of the package, its version history, and usage statistics.
