Papaya CMS licensing FAQ
Another translation of the reference material on licensing another CMS is ready - this time it will be about the German project papaya CMS (according to Wappalyzer , it is the basis of such Internet resources as jpk.com , the site of one of the leading manufacturers of nanoanalytical equipment). This system is distributed under the terms of a double license: both GPL and commercial. Although the FAQ is small in scope, but in my opinion, quite informative. See it below.
Can I use papaya CMS for a commercial site, for example, for a site of our company?
Yes, you can create a company website using papaya CMS without the need for any royalties. You need to purchase a commercial license only if you plan to engage in your own distribution of papaya CMS or extensions / modules to papaya CMS.
Can I change the papaya CMS and sell it as a closed source program using my own license?
Distribution of modified source code is permitted only under the terms of the GPL. This means that the source code must be freely available and that you must give users the right to modify and distribute the source code. If you do not plan to distribute the source code in this way, you need to purchase a commercial license, on the basis of which you can realize any form of commercial use.

I downloaded the papaya CMS and want to modify the source code or distribute it under the terms of the GPL. Can i do this
Yes, these are the benefits that the GPL provides to you as a user. You have the right to view the source code, modify it and distribute it. The only thing you need to keep in mind is that you must distribute the code under the terms of the GPL.
The company uses a modified version of papaya CMS for its corporate website. Does the company have to publish the modified source code? This is what the GPL requires, right?
Not at all. The GPL allows you to modify the source code of a program and use the program for your own purposes without having to publish or distribute the source code. One of the basic ideas of the GPL is to give users the freedom to modify the software and use the modified software without incurring any responsibility. In the above example, the company, however, is not required to publish the source code. If a company wants to distribute modified software, for example, by downloading from the company's website, the software distributed must be licensed under the terms of the GPL. If the company wants to distribute the software on the terms of its own license, for example, the license for software with closed source code, the company must purchase a commercial license papaya.
What is the pricing model for a commercial license?
License fees for commercial modules are charged once, not repeatedly.
What license for papaya CMS should I choose for developed modules?
It depends on how the module is connected to the papaya CMS. If a module can only work with papaya CMS in the sense that it cannot work as a standalone program, you must license it under the GPL. All GPL conditions must be met when you distribute the module. If you want to distribute a module under a license other than the GPL, you need to purchase a commercial papaya license. If the module can work as a standalone program and does not depend on the papaya CMS, you are free to choose a license.
What types of licenses are offered?
papaya CMS is dual licensed: You can download papaya CMS for use and distribution under the GPL. It's completely free, and the GPL gives you a lot of freedom. As an alternative, you can purchase a commercial license that may best suit your particular use. You can learn more about the licensing policy on our website.
Am I forced to use the GPL when I extend the system core of the papaya CMS by adding a new feature?
Yes, the papaya CMS is published under the terms of the GPL, which implies that any software derived from the papaya CMS and all extensions must also be licensed under the terms of the GPL. As an alternative, you can buy a papaya commercial license, which will give you the right to publish your extensions and modifications under an alternative license. You can learn more about the details of the licensing model.
