= Open Source !VirtualBox and other editions = After several years of intensive development, !VirtualBox was released as Open Source in January 2007. !InnoTek has chosen to release its !VirtualBox source code under the [wiki:"GPL" GNU General Public License (GPL)]. If you are interested in using !VirtualBox -- either for private or business use --, you have the choice between two versions: * The full '''!VirtualBox''' package is available in binary (executable) form free of charge from the [wiki:"Downloads"] page. This version is free for personal use and evaluation under the terms of the [wiki:"VirtualBox PUEL" VirtualBox Personal Use and Evaluation License]. If, instead, you wish to purchase licenses for enterprise use and/or enterprise support for !VirtualBox, please do not hesitate to contact InnoTek. * The '''!VirtualBox Open Source Edition (OSE)''' is the one that has been released under the GPL and comes with complete source code. It is functionally equivalent to the full !VirtualBox package, except for a few features that primarily target enterprise customers. This gives us a chance to generate revenue to fund further development of !VirtualBox. !VirtualBox OSE is also available from the [wiki:"Downloads"] page. The exact functional differences between the two versions can be found [wiki:"Closed Source Features" here].
