Emby (formerly Media Browser)[1] is a media server designed to organize, play, and stream audio and video to a variety of devices.[2] Emby's source code is mostly open with some closed-source components as of August 2017[3], releases of the software published via the Emby website are however proprietary[4] and cannot be replicated from source due to the build scripts also being proprietary. As of version 3.5.3 Emby has been relicensed and is now closed-source, while open source components will be moved to plugins.[5] Emby uses a client-server model.
