About this Site
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.
Note to software creators: first of all, thanks for making free, open-source software– we love you. Second, many F/OSS projects have very confusing download pages, and this prevents a lot of people from using free software. It’s usually very easy to improve– just add a big ‘Download Now’ link towards the top of the page, without too much clutter around it (use mozilla.org or adiumx.com or bittorrent.com for inspiration)– people do not need to see every version and every mirror. Here’s some more unsolicited advice for getting more people to download your software: a. if you have a nice icon, show it off prominently. b. put a download link and a screenshot on your front page. c. if you use mirrors, use a script to pick a random mirror and just give people one link that says ‘download now’ d. if there’s any way you can avoid sending people to the sourceforge download mirror page, you should (we know it’s not your fault, but it baffles lots of folks). e. if you really want to make things easy for people, and you have a cross-platform app, detect what OS they are on and give them the correct link. f. test your page on a novice!
