Frozen is released under commercial and GNU GPL v.2 open source licenses.
Commercial Projects: Once your project becomes commercialised GPLv2 licensing dictates that you need to either open your source fully or purchase a commercial license. Cesanta offer full, royalty-free commercial licenses without any GPL restrictions. If your needs require a custom license, we’d be happy to work on a solution with you.

Prototyping: While your project is still in prototyping stage and not for sale, you can use Frozen’s open source code without license restrictions.
