Free and open source software is software that has been written specifically to be given away. The software is written by teams of volunteers - some sponsored, others just for the satisfaction of seeing the world made a better place by better software. Software Freedom Day is a global celebration of the best of free and open source software. Events are held worldwide on the 20th of September to showcase software, answer questions, and give away copies of free software. Every application shown here is free - free to download, free to use, free to distribute. Most are written to work on any computer, whether it's running Windows, MacOS or Linux.Have you made the step?
