Radarr is Sonarr’s design applied to films: build a wanted list, define quality preferences, and it acquires and files matching releases automatically.

Films need different logic than TV

Television is a stream of episodes on a schedule; films are individual titles that may not have a good release for months after announcement. Radarr accounts for that with availability settings that control when it starts searching, whether at announcement, in cinemas, or at physical or digital release. Setting this wrong is why people find Radarr grabbing poor camera rips: it was told the film was available before a proper release existed.

Quality profiles and custom formats

Profiles define acceptable resolutions and sources in preference order with an upgrade cutoff. Custom formats add scoring on release attributes, so you can prefer particular audio formats or specific release groups and penalize others. This is where most tuning effort goes for people who care about consistency across a library.

The surrounding stack

Prowlarr for indexer management, qBittorrent or SABnzbd for downloads, Bazarr for subtitles, Sonarr for television, and Overseerr or Jellyseerr so other people can request titles without touching Radarr itself.

Setup detail worth getting right

Use consistent paths across Radarr and the download client, keep downloads and library on the same filesystem so hardlinks work, and let Radarr do the renaming. Fighting it with manual file management is how libraries end up in a state neither you nor Plex can parse.

Access

Keep it off the public internet and reach it over a VPN. Ruddarr and nzb360 are the mobile options.

Radarr is released under the GNU General Public License v3.0.
