List of free and open-source software packages

[1] 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.Some of the open-source applications are also the basis of commercial products, shown in the List of commercial open-source applications and services.Servidor Be advised that available distributions of these systems can contain, or offer to build and install, added software that is neither free software nor open-source.
