debfoster is described as 'Debian uses the main programs apt and dpkg to manage packages. These programs do not make a distinction between packages that got installed because some other program happened to need it and packages you really asked for' and is an app in the OS & Utilities category. There are six alternatives to debfoster for Linux, Debian, Xfce and Windows. The best alternative is Synaptic, which is both free and Open Source. Other great apps like debfoster are aptitude (Free, Open Source), localepurge (Free, Open Source), deborphan (Free, Open Source) and NeoSetup Updater (Freemium).
Synaptic is a graphical package management program for apt. It provides the same features as the apt-get command line utility with a GUI front-end based on Gtk+. * Install, remove, upgrade and downgrade single and multiple packages. * Upgrade your whole system.
deborphan finds packages installed on your Debian/GNU system that have no other packages depending on them. Its primary goal (and default action) is to trace unused libraries. A dialog frontend, orphaner, is included in the package for easy removal of packages.
NeoSetup is a brand new concept of application installer and updater for Windows. It detects updates quickly and installs them at a click of a button. It will perform automated application installations from a collection of the most popular Windows programs.
GtkOrphan (a Perl/Gtk2 application for debian systems) is a graphical tool which analyzes the status of your installations, looking for orphaned libraries. It implements a GUI front-end for deborphan, adding the package-removal capability.
