What is Radarr?
Radarr is a movie collection manager for Usenet and BitTorrent users. It automatically monitors multiple RSS feeds and indexers for new and upgraded releases of your wanted movies, grabs them through your download client, then renames and organizes them into your library. Think of it as the movie-focused sibling of Sonarr — part of the broader *arr stack alongside Prowlarr, Sonarr, and Bazarr.
Radarr handles quality profiles, custom formats, automatic upgrades (e.g. replacing a 720p copy when a 1080p release appears), and list-based imports from sources like Trakt, IMDb, and TMDb.
Radarr pairs best with Prowlarr (indexer management) and a download client such as qBittorrent or SABnzbd. Set those up first for the smoothest experience.

¶ 2.1 Authentication
Before anything else, lock down access:

- Select your client (e.g. qBittorrent or SABnzbd).

¶ 2.3 Connect Indexers via Prowlarr
Rather than adding indexers manually, let Prowlarr manage them:
- In Prowlarr, go to Settings → Apps and add Radarr.
- Enter the Radarr URL (
http://radarr:7878) and API key (found in Radarr under Settings → General → Security). - Prowlarr will sync all your indexers to Radarr automatically.
¶ 2.4 Quality Profiles & Root Folder
- Go to Settings → Media Management and add a Root Folder pointing to
/data/media/movies. - Under Settings → Profiles, configure quality profiles to match your storage and bandwidth.
- For curated custom formats and quality scoring, consider Profilarr to manage profiles across Radarr and Sonarr.
