Coldarr

Storage tiering for Radarr and Sonarr libraries. Keep recent and favorite media on primary storage and move cold titles to overflow drives.

Coldarr looks at your library's age, size, tags, quality profiles, monitored state, Jellyfin Favorites, and available disk space. It asks Radarr and Sonarr to move eligible items, so their databases stay the source of truth. Coldarr never moves files directly.

With qBittorrent, it can also move finished downloads off a fast download drive onto seed storage once they've settled, and clear them out once your trackers' seeding requirements are met - see Downloads and seeding.

Preview, then apply

Use the web interface or CLI to inspect storage and build a dry-run plan. Review what would move, why, and where before applying it. Both interfaces use the same configuration, and scheduled jobs stay off until enabled.
