Radarr is a personal video recorder (PVR) but instead of relying on a cable signal, it uses Usenet and BitTorrent. With Radarr you can monitor RSS feeds for your favourite films, and it will automatically grab, sort, and rename them.
Radarr is a fork of Sonarr, which does the same job but for television shows. However, since its beginnings, Radarr has made strides in terms of the interface and experience. Version 3 brought with it a massive upgrade to the web dashboard, and you wouldn’t know that Radarr was a fork of Sonarr any more.
