It is time to share a list of the best 25 Free and Open Source Software I found during the year 2021. Some of these programs may not be new in that they weren’t released for the first time in 2021, but they are new and have been helpful to me. It is in the spirit of sharing that I’m writing this article hoping you find some of these programs useful as well.
To begin, you may want to search for the program using your distribution’s package manager, like so:
Fedora and derivatives:
# yum search all package Or # dnf search all package
Debian and derivatives:
# aptitude search package
OpenSUSE and derivatives:
# zypper search package
Arch Linux and derivatives:
# pacman -Ss package
If your search returns no results, head over to the website of each tool where you will find the standalone package for download and installation instructions, along with information on dependencies.
