From my reading of the following I your README, I think your understanding of the GPL might be slightly wrong > This project is licensed under the GPL. In simple terms, this means you can use it for free in open source projects that are also licensed under the GPL. If on the other hand you want to use the project for a proprietary app where you don't want to open source the code, then you need a commercial license. The price for one developer is EUR 79 if you purchase before Feb 11, 2018, EUR 99 after. One year of updates is included. To obtain a license, click here. If I understand what you are saying, you say that to use the output of your program one needs to GPL everything, which is not usually how GPL is interpreted. For example I can use GIMP to create graphics that I can use without any form of restrictions. The GPL applies to GIMP itself, not its outputs. However, since your product builds executables then if the resulting installer file was built from GPLed code then you are partially correct IMO -- users would be required to distribute the installer source in compliance with GPL. However, while I have not looked into how the build process works for your product I have a hard time imagining that the GPL would require users to GPL the installation target source, since those are a separate set of files. IANAL

i read it as saying it's for programming projects. And the output of a programming project is code. And you can't use this project if you don't reduce the code of your own (programming) project - in that case you would need a commercial license.

IANAL either but believe you are right with the GIMP example. However, my project doesn't just produce an output similarly to how GIMP saves images. It also requires you to link to some of my project's code at runtime. That is where the need for a commercial license comes from.
