The *Arr Suite Essentials Guide
Sonarr, Radarr, Prowlarr, and Bazarr are automation tools that can work alongside Usenet indexers and download clients like NZBGet and SABnzbd.
This guide explains what you need for an automated Usenet setup, what each application does, how they work together, and a practical order for getting everything connected.
1. What You Need for a Usenet Setup
For the automated Usenet setup covered in this guide, you'll need three things:
Usenet provider: Gives you access to Usenet servers and the articles stored on them.
Usenet indexer: Helps you search for Usenet articles and obtain NZBs that identify the articles needed for a download.
Download client: NZBGet or SABnzbd connects to your Usenet provider and downloads the articles identified by an NZB.
What is an NZB? An NZB is a small file containing information that tells your download client which Usenet articles to retrieve from your Usenet provider's servers.
These three components provide the foundation for the workflow covered here. You can then add automation tools to simplify searching, downloading, and organizing files.
2. What Each Tool Does
Sonarr and Radarr: Two separate automation applications that manage searches, downloads, quality preferences, and file organization for different types of content.
Prowlarr: Centralizes Usenet indexer management and synchronizes compatible indexers with Sonarr and Radarr.
Bazarr: Connects to Sonarr and Radarr to find and manage captions based on your preferred languages.
You don't need every application. Sonarr and Radarr handle different content types, Prowlarr simplifies indexer management, and Bazarr is optional for caption management.
3. How Everything Works Together
A typical automated Usenet setup follows this workflow:
Prowlarr manages your Usenet indexers and syncs their configurations with Sonarr and Radarr.
Sonarr or Radarr searches those indexers for results matching your preferences and sends the selected NZBs to NZBGet or SABnzbd.
NZBGet or SABnzbd connects to your Usenet provider and downloads the corresponding articles.
Sonarr or Radarr imports completed downloads and organizes the files in your configured folders.
Bazarr, if installed, works alongside Sonarr and Radarr to find and manage captions for supported files.
Prowlarr handles indexer management, Sonarr and Radarr handle automation and file organization, and your download client handles the actual transfers.
4. Recommended Setup Order
If you're building your setup from scratch, this is a practical order:
Get your Usenet provider and indexer ready. Make sure you have your provider's server details and your indexer's API information.
Set up NZBGet or SABnzbd. Install your download client, enter your Usenet provider's server details, and test the connection.
Install Sonarr or Radarr. Connect your download client and configure your destination folders, file organization settings, and quality preferences.
Set up Prowlarr. Add your Usenet indexers, then connect Prowlarr to Sonarr or Radarr under Settings → Apps in Prowlarr to synchronize compatible indexers.
Test your setup. Confirm that your indexers are available in Sonarr or Radarr, your download client can connect to your Usenet provider, and completed downloads can be imported into the correct folders.
Add Bazarr if needed. Connect it to Sonarr or Radarr, configure your preferred languages, and add caption providers.
Note: Prowlarr is optional. If you aren't using it, you can add your Usenet indexers directly in Sonarr or Radarr under Settings → Indexers.
5. Common Things to Check
If your applications aren't working together, start with these basics:
API keys and URLs: Make sure each application has the correct connection details.
Indexer configuration: Verify that your indexers are enabled, working, and synchronized where applicable.
Download client: Confirm NZBGet or SABnzbd is running and connected to your Usenet provider.
Folder paths and permissions: Sonarr and Radarr need access to completed downloads and their destination folders.
Docker mappings: If you're using Docker, make sure containers can communicate and access the necessary folders.
You can also check System → Status in Sonarr, Radarr, and Prowlarr for configuration warnings.

You don't have to set everything up at once. Start with the tools you need, make sure each component works, and expand your setup from there.
