Is OpenRate open source?

Yes, OpenRate is dedicated to developing and supporting an open source solution to complement and compete with the complicated and expensive commercial offerings that are available.
We believe that the advantages of Open Source software are about to be discovered by major players, who are becoming more and more interested in flexibility and time to market, and are not being offered this by traditional "rigid" products. The whole OpenRate concept is aimed to allow you to make the most of the work that we have done (the framework, the existing plugin modules, which cover all of the basic needs for rating and mediation), while still being offered an open road to allow you to develop custom modules, using standard tools (NetBeans or Eclipse) and a strong architecture.
OpenRate is, and will remain open source.
