25 Free Open Source Applications

Discovering 25 Open Source Applications That Cost Nothing in 2023

It is time to share a list of the best 25 Free and Open Source Software I found during the year 2022. Some of these programs may not be new in that they weren’t released for the first time in 2022, 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:

The RHEL-based distribution users can use the yum or dnf package manager:

# yum search all package
# dnf search all package

The Debian-based distribution users can use apt or aptitude package manager:

# aptitude search package

OpenSUSE and derivatives can use the zypper command:

# 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.

1. SimpleScreenRecorder

You can use Simple Screen Recorder to make audio and video screencasts (entire screen or selected area). It is easy to install and use, but powerful at the same time.

Jaspersoft Studio is a report designer program that allows you to create simple and sophisticated reports as well with charts, tabs, tables (and everything you can expect to see in a world-class report) and export them to a wide variety of formats (with PDF perhaps being the most common).

With Q&A forums and User groups, plus several samples and examples, the community website is a great resource for help to master this versatile program.
