How to Link NZBGet with Sonarr, Radarr, and Other Tools

NZBGet becomes significantly more powerful when paired with other automation tools like Sonarr, Radarr, Readarr, and Prowlarr. These applications handle search, scheduling, and renaming—while NZBGet focuses purely on downloading.

This guide shows you how to connect NZBGet with each major companion app and indexer manager.
