Features

Everything you need to manage capacity

Capacitarr brings intelligence to media library management with powerful scoring, flexible rules, and deep integrations.

Smart Scoring

Score media across multiple dimensions — age, file size, popularity, watch history, and more. Every score is transparent and fully explainable.

Deep Integrations

Native support for 9+ services. Pull data from your *arr apps, media servers, and request managers into a single unified view.

Cascading Rules

Build sophisticated rule chains with conditions, weights, and thresholds. Rules cascade and compose for complex cleanup policies.

Safety First

Preview everything before it happens. Safety guards, dry-run mode, and a complete audit log ensure nothing is deleted by accident.

Notifications

Get alerted via Discord, Slack, or in-app notifications when the engine runs, scores change, or items are flagged for cleanup.

Docker Native

Single container, zero external dependencies. Deploy in seconds with Docker Compose. Works on any platform, any architecture.
