And the main console program uses a proprietary license

Also Python + Qt is too vague. Which package are you using ? PySide2/6 ? PyQt5/6 ?

And I wrote the interface in PySide6. In other words, an interface is an implementation of my program's api. (I will periodically respond by editing my post, as the forum forbids me to send messages more than one in 10 minutes, sorry)

WARNING: I am NOT a lawyer.

@Welli96 said in Open source and commerce.:

Hi! I'm a developer. Am I violating the right to use an open source license if I sell my program, but at the same time the program interface will be separated from the body of the main program and will be publicly available on github.

This last sentence is pretty unclear. How do you separate the interface and the body ? Which licence(s) are you using ?

Depending on your licence(s) there are rules to follow in order to abide by them. Did you check them ? Are you following them properly ?
