Huntarr

Huntarr is a companion automation service for the *arr ecosystem that continuously scans your libraries for missing content and items below your quality cutoff. It then triggers searches in small, controlled batches to gradually complete and upgrade your collection while staying gentle on indexers.

Key Features

• Integrates with Sonarr, Radarr, Lidarr, Readarr, and Whisparr to analyze monitored libraries
• Automatically hunts missing items, skipping unreleased content and reducing load by avoiding unnecessary metadata refresh
• Quality-upgrade hunting for items below your configured cutoff, with configurable batch sizes per cycle
• Download-queue aware behavior (can pause actions when the queue exceeds a threshold)
• Built-in indexer-friendly API management, including hourly caps and consistent timeouts
• Continuous run loop with configurable intervals between cycles

Use Cases

• Keep a “mostly complete” library progressing toward complete coverage without manual searches
• Automatically push upgrades (better quality releases) for existing items over time
• Run a hands-off media automation workflow alongside existing *arr applications

Limitations and Considerations

• Requires existing, correctly configured *arr applications and indexers; Huntarr triggers searches but does not replace the *arr stack
• Effectiveness depends on indexer availability, rate limits, and your monitoring/quality settings

Huntarr fits best as a lightweight, always-on background utility for media automation setups that want continuous completion and quality improvement. With conservative batching and rate controls, it aims to enhance automation without overwhelming your services.
