Licensing

An often arising question is: Can I use KDE to develop commercial applications? - Yes, you can develop commercial applications for KDE. KDE's foundation libraries kdelibs and kdepimlibs, as well as KOffice libraries and other major supporting applications, are licensed under the LGPL. The LGPL allows the linking of closed source applications against those libraries. Though, a Qt developer license is required for closed source development.
