The first step in learning about eXo platform licensing is to understand what General Public Licensing (GPL) is and how it compares with commercial non-GPL license.
GPL is a type of license that is intended to make sure software is free for all its users. Though it seems to be fairly straight forward, the complexity behind this license requires you to learn more about the exact terms and conditions in the free software foundation website. However, in simple term eXo platform and its core products are free for any GPL users in the following cases:
Your application is under the GPL license. In this case, you are free to ship our products with your application without any additional written agreement with us. We welcome you, however, to stay in touch for marketing and partnership opportunities.
You never copy, modify or distribute. If you never copy, modify or distribute eXo platform products, you are free to use them. But, be careful:
  • Modifying and distributing.
  • You are free to modify eXo platform as you please. However, if you distribute the modified version, all changes, all interface code and all code connecting directly or indirectly to the latter fall under the GPL license.
  • Copying.
  • You are allowed to copy the eXo platform binaries and source code, but the copies will automatically fall under the GPL license.
    Commercial non-GPL license is a license that allows you to create proprietary application without distributing and sharing the source code of your application. Benefits of acquiring commercial non-GPL license are:
    Under the commercial license the eXo platform SARL takes responsibility for its products, whereas there are no warranties or representations from the developer under the GPL license.
    If you have any doubt about the licensing issues, we recommend that you use the commercial license. This may save you a lot of trouble, and you are never wrong. Besides, the prices per annual subscription for our products are way below the industry average.
