Maintainerr, an open source, rule based media collection manager that connects to Plex plus Overseerr or Jellyseerr and the arr apps to keep your library tidy automatically.
Maintainerr is a free, open source, self hosted media collection manager. It connects to Plex together with Overseerr or Jellyseerr and the arr apps, Sonarr and Radarr, then applies rules you define to keep a media library tidy without manual effort. Rules are built from properties across your connected services, and Maintainerr evaluates them on a schedule to find unwatched, unrequested or otherwise stale media, which it can add to a Plex collection for review or remove outright. A clean web interface lets you build, preview and manage rules and collections, set exclusions, and wire up notifications. It suits any household or team running a media server that wants storage kept under control and old content retired on a predictable, automated basis rather than by hand.
Maintainerr has no built in login of its own because it is designed to run behind a reverse proxy, so cloudimg closes that gap for you: the application is bound to the loopback interface only and fronted by an nginx HTTP Basic Auth gate whose password is generated uniquely on each machine at first boot, so no default password and no shared secret ever exist in the image and an unauthenticated request is refused. A fresh per instance database and API key are created automatically on first boot, an unauthenticated health endpoint is exposed for load balancer and uptime probes, systemd manages the service for automatic restarts and clean logging, and every deployment carries a paired deployment guide and 24/7 support.
