We believe Open Source is key to a long-term sustainable and prosperous technology community. The Encore framework builds on Open Source software, and is itself Open Source. This means the Encore framework is free to use and open to contributions.
The Encore framework is Open Source under Mozilla Public License 2.0.
The MPL is a simple copyleft license. The MPL's "file-level" copyleft is designed to encourage contributors to share modifications they make to your code, while still allowing them to combine your code with code under other licenses (open or proprietary) with minimal restrictions.
You can learn more about MPL 2.0 on the official website.
