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. If you think we're missing any great apps, please let us know: info@bestfreesoftwarelist.com

Free & open-source software is good for you & for the world. This is the best Windows software that we know of. No adware, no spyware, just good software.
