List of Free & Open-Source Software in 2020

Free Software List & Open Source: This is an inventory of free and open-source software packages, computer software licensed under free software licenses, and open-source licenses. Software that matches the Free Software Definition could also be more appropriately called free software; the GNU project especially objects to their works being mentioned 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 the other way around. a little fraction of the software that meets either definition is listed here.
