About

Open Source Windows is a simple list of the best free and open source software for Windows. We aren't trying to be a comprehensive listing of every open-source Windows application, instead we want to showcase the best, most important, and easiest to use. This page should be a handy reference and a useful tool for getting more people to start using free and open-source software.
