Welcome!
Are you looking for an open source alternative to commercial solutions?
Do you want to learn how to use new tools that make your work, research, or hobbies easier?
Choose a topic that you are interested in and start exploring. Each entry point is a theme area in which you will find not only useful tools, but also tutorials how to use them. Some projects are funded by the NLnet Foundation, while others operate independently. All, however, are driven by passionate open-source communities. In addition, you will also find a comparison of the commercial and open source tools that are most widely used in that area.
