What is Sonarr?

Sonarr is a personal video recorder for downloaders. You add the shows you follow, and it monitors RSS feeds for new episodes, sends releases to SABnzbd, NZBGet or a torrent client, then sorts and renames the files into your library. It can scan an existing collection and fetch missing episodes, swap in better-quality copies later, retry when a download fails, and handle specials and multi-episode files. It notifies Kodi and Plex and updates their libraries. A web UI runs on Windows, Linux, macOS and Raspberry Pi.

Good fit if

  • You keep a TV library on a home server and want new episodes to arrive and get organized without manual work.
  • You already use a Usenet or torrent client and a media server.

Look elsewhere if

  • You want the player or streaming server itself: Jellyfin or Kodi.
