List of free and open-source software packages

This article is about software free to be modified and distributed. For examples of software free in the monetary sense, see List of freeware.

This is a list of free and open source software packages: computer software licensed under free software licenses and open source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open source. For more information about the philosophical background for open source software, see free software movement and Open Source Initiative. However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa. A small fraction of the software that meets either definition is listed here.
