Open Source Apps

1221 apps ( Last updated: 5 days ago )

Having public code isn't just a philosophy: it means anyone can audit, fix, and improve it. That is why some of the most reliable and long-lasting apps out there are open source. On Windows, you'll find alternatives like this for almost any task (video editing, office work, security, development) and many of them, like VLC or GIMP, have spent decades competing head-to-head with paid software. No subscriptions. No licenses. Backed by communities that never stop updating them.
