SDK Licensing

The DZX SDK is dual licensed and can be used under an open source or a commercial license.

The SDK can be used for free under the terms of the GNU General Public License version 3 (GPLv3). Although free, this license has requirements that must be met if you choose this license.

For those creating proprietary closed source applications, or those who cannot meet the requirements of the open source license, we offer a commercial license. The commercial license removes all obligations imposed by the open source license.
