The TwoDesk Component library is 100% GPL (General Public License). If your software is also 100% GPL compliant, then we do not require you to pay us for licenses. We do request (but do not require) that if you release your software publicly, you let us know. We believe this a fantastic opportunity for the open source community and for those of you who develop open source software.
The formal terms of the GPL license can be found in the GNU General Public License section of the component library reference manual. Please note that the GPL can be very restrictive, so if it doesn't meet your needs, you are better served by our commercial license.
Specifically:
If you represent a non-profit organization or academic institution, we recommend that you publish your application as an open source/free software project using the GPL license. If you do so, you will be free to use the TwoDesk Component Library free of charge. If you have strong reasons not to publish you application in accordance with the GPL, then you should purchase commercial licenses.
If you are a private individual, you are free to use TwoDesk Components for your personal applications as long as you do not distribute them. If you distribute them, you must make a decision between the Commercial License and the GPL.
Please note that even if you ship a free demo version of your application, the above rules apply.
Please note that TwoDesk Software Company can only give advice on which license is right for you. The final judgement, of course can be made only by a court of law. With that said, we recommend the commercial license to all commercial and government organizations. This frees you from the broad and strict requirements of the GPL license.
To all free software enthusiasts we recommend TwoDesk components under the GPL license.
To anyone in doubt, we recommend the commercial license. It is never wrong.
