Radarr

Radarr is a self-hosted movie collection manager designed for users of Usenet and BitTorrent. The application monitors RSS feeds for new movie releases and interfaces with download clients and indexers to automate the process of grabbing, sorting, and renaming files. It is deployed as a server application and is compatible with Windows, Linux, macOS, and Raspberry Pi.

The software manages a movie library by tracking desired titles and automatically importing downloaded files into a structured directory. It can be configured to monitor for higher quality versions of existing files and trigger automatic upgrades, such as moving from a DVD rip to a Blu-Ray rip. Because the system supports only one version of a specific movie per instance, users requiring multiple formats like 4K and 1080p must run separate instances of the application to manage those distinct libraries.

Key features

• Automatic movie importing and renaming
• Quality monitoring and automatic file upgrades
• Integration with SABnzbd, NZBGet, QBittorrent, Deluge, and Transmission
• Support for RSS sync and manual release searching
• Metadata import for posters, trailers, and subtitles
• Automatic handling of failed downloads by attempting alternative releases
• Recognition of Special Editions, Director's Cuts, and AKA movie names
• Integration with Kodi and Plex for library updates and notifications

Radarr integrates with various download clients and media players to create a centralized pipeline for film acquisition. It uses customizable profiles to ensure the software selects releases that meet specific user criteria regarding file size or source. The system also identifies releases with hardcoded subtitles to avoid unwanted versions during the automated search process. By combining RSS synchronization with manual search capabilities, the software allows for both passive monitoring and active hunting for specific titles.

This tool is intended for home media server enthusiasts who want to automate the curation and organization of their movie libraries across different operating systems.
