See example screenshots below

This page lists good quality free and open-source software that anyone can download at no cost and use or modify freely. Plenty more quality open-source software exists – this is just an introductory sample. Most of these programs are cross-platform, meaning they can be installed on MS Windows, Mac OS X and Linux.

The software below is not freeware or shareware, which are both significantly different to open source.
