Community edition

Cheerp is open-source software, and is free for uses compliant with the GPLv2 license. You can use Cheerp at no cost for any of these projects, as well as for technical evaluation purposes. A GitHub project is available for bugtracking and feature requests.

You can use this license to develop any open-source application (including commercial) as well as closed-source, non-commercial applications. As parts of Cheerp are licensed under GPLv2, a copyleft license, if you distribute your application you must provide your users access to its sources under the same license.

If you are using Cheerp for developing closed-source, commercial applications you must purchase a commercial license.
