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 11 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. Approval queue, safety guards, dry-run mode, and a complete audit trail ensure nothing is deleted by accident.
Real-Time Updates
Server-Sent Events push engine state, deletions, and activity to the browser instantly — no polling. 67 typed event types keep you informed.
Docker Native
Single container, zero external dependencies. Deploy in seconds with Docker Compose. Works on any platform, any architecture.
