# Prowlarr

Prowlarr is the indexer management layer for the *arr stack. It aggregates indexers (torrent and Usenet) and exposes a unified API that Sonarr, Radarr, Lidarr, and Readarr consume.

**Host:** Dankserver — **Hostname:** `prowlarr.dankserver.local` — **Docs:** https://wiki.servarr.com/prowlarr

## Gotchas

- Prowlarr database grows with indexer data. Set up periodic vacuum/backup.
- Indexer sync has a 15–60 minute delay. Search results may lag.
- Rotate API key: update it in every arr app.
