Open Source License: General Public License (GPL)
KlayGE’s default license is the GNU General Public License 2.0. In other words, anyone can use it and access to its source code, as long as the project which uses KlayGE must be released under GPL 2.0 license. See the full text of the license here: gplv2.txt.
Open source is a very powerful way of development. It encourages collaboration, cooperation, and user freedom. Open source software’s source code is 100% accessable; free from hidden malware, spyware and viruses.
Proprietary License: KlayGE Proprietary License (KPL)
For whatever reason some users feel that they cannot comply with, or would prefer not to comply with the conditions of the GPL. For example, you wish to use the KlayGE without releasing your source code publicly.
To allow users with these issues to still consider using KlayGE, starting from 4.0, an alternative license, the KlayGE Proprietary License (KPL), is available for a license fee. Thus users who have a specific need to avoid the conditions of the GPL for their projects have the option of paying for a different license.
If you are interested in obtaining this proprietary license, please contact us for more details.
