List of open source software packages

From Wikipedia, the free encyclopedia

This is a list of open-source software packages: computer software licensed under an open-source license. 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 Open Source Definition also meets The Free Software Definition. Software that meets either is listed here.
