License
From JUCE
JUCE is released under the Gnu Public Licence, which means it can be freely copied and distributed, and costs nothing to use in open-source applications.
If you'd like to avoid the restrictions of the GPL and use JUCE for a closed-source product, you can purchase a commercial licence. This can either cover a single product or can apply to all products that your company releases.
More information about pricing and how to apply is available on the main website.
