Nixstaller is described as 'Open Source project with the goal to create user friendly and flexible installers that work on various UNIX like systems' and is a Software Installer in the OS & Utilities category. There are five alternatives to Nixstaller for a variety of platforms, including Windows, Linux, Mac, BSD and PortableApps.com. The best alternative is Inno Setup, which is both free and Open Source. Other great apps like Nixstaller are NSIS (Free, Open Source), Makeself (Free, Open Source), MojoSetup (Free, Open Source) and InstallBuilder (Paid).
NSIS (Nullsoft Scriptable Install System) is a professional open source system to create Windows installers. It is designed to be as small and flexible as possible and is therefore very suitable for internet distribution.
makeself.sh is a small shell script that generates a self-extractable tar.gz archive from a directory. The resulting file appears as a shell script (many of those have a .run suffix), and can be launched as is.
Putting together a MojoSetup installer involves five general steps: 1) Compile the software. 2) Set up the installer filesystem structure. 3) Write a config file. 4) Add any localized strings. 5) Package up the final file for distribution.
