Prowlarr

Indexer manager. Add usenet indexers once here and they sync to Sonarr/Radarr automatically.

Web UI: http://<host>:9696

First-Time Setup

1. Configure Sonarr/Radarr first — they need root folders and download clients before Prowlarr can sync to them.
2. Add Indexers — Indexers > Add (+). Enter credentials and test each. See Usenet Indexers.
3. Connect Apps — Settings > Apps > Add Application. Add Sonarr and Radarr with their URLs and API keys, sync level Full Sync.
4. Verify — the indexers should appear in Sonarr/Radarr under Settings > Indexers.

Things to Know

• Prowlarr is not an indexer. It pushes indexers to the *arrs; don't add it as one.
• Its API is /api/v1/, not the /api/v3/ that Sonarr and Radarr use, and it sets no UrlBase by default. Both mistakes return a 200 with the SPA's HTML, which reads like a bad API key.
• Keep the database on local storage. SQLite corrupts on NFS/SMB.
• Indexers go down. Check the Indexers page when grabs dry up.

This stack is pinned to a -nightly tag. Moving to stable is a downgrade across a database migration, which Prowlarr does not support — it needs a restore from ${CONFIG_ROOT}/config/prowlarr/Backups/, not just an image swap.
