Licensing & Pricing (EN)
We use the sustainable dual licensing model, in which both the open source and the traditional closed source software distribution models are combined.
Open Source Licensing
If you are developing and distributing open source applications under the GNU General Public License (GPL), as published by the Free Software Foundation, then you are free to use all our QP™ Real-Time Embedded Frameworks under the GPL version 3 of the License, or (at your option) any later version. Please note that GPL requires that all modifications to the original code as well as your application code (Derivative Works as defined in the Copyright Law) must also be released under the terms of the GPL open source license.
Open Source Licensing
If you are developing and distributing traditional closed source applications, you can purchase one of Quantum Leaps commercial licenses, which are specifically designed for users interested in retaining the proprietary status of their code. All Quantum Leaps commercial licenses expressly supersede the GPL open source license. This means that when you license our QP™ Real-Time Embedded Frameworks under a commercial license, you specifically do not use the software under the open source license and therefore you are not subject to any of its terms. Commercial licensing options are described below.
