Juce licensing question

i am looking into juce and i have a licensing question
open source projects are regarded free of charge projects?
i mean what if a project is open source and commercial at the same time?
purchase it and get the source code. or get the source code or pay for the compiled binary

what juce license do i need then?

Hi there,

JUCE is free as long as the source code of your application is available wherever the binary is distributed.
So, if you release the source code, it doesn’t matter whether you also sell the application, you don’t need to pay for a license. Note, however, that the GPL license of JUCE remains applicable to your customers, and you must take the necessary measures to communicate this to your customers (for example, commented lines above the JUCE code stating that this source code is GPL licensed).

Best regards,
