Free as in freedom
Kopano is not only open-source software, but at Kopano we are a free software company by heart as well. Therefore we are publishing all the software we are producing under a well accepted license (which is the AGPLv3).
Developers interested in our software can easily clone the same repositories that we are building our products from. In addition to this we are providing nightly build of our software so everyone can have easily test and run the latest in-development state.
Additionally we pledge to help downstream maintainers in providing builds of our software to the community free of charge.
