Libresonic is a web based music streamer with transcoding capabilities. In contrast to Sonarr, Radarr and Headphones it does not download new content but rather manage and provide convenient access to existing collections. Unlike Subsonic or Madsonic it is free and has no limitations.
Radarr is a movie download manager capable of downloading from BitTorrent and Usenet. It is a fork of Sonarr and is comparable to Couchpotato or Headphones. It integrates with rTorrent, uTorrent Server, Deluge, NZBGet and many more downloaders. It can also make use of Jackett to communicate with BitTorrent trackers.
