## What it is
Prowlarr is a self-hosted indexer manager and proxy for torrent trackers and Usenet indexers, built on the *arr (.NET/React) stack. It centrally manages indexers and syncs them to PVR apps like Radarr, Sonarr, Lidarr, Readarr, and Mylar3, with manual search, statistics, and proxy support.

## Use cases
- manage torrent trackers and usenet indexers in one place
- sync indexers to radarr and sonarr automatically
- self-hosted indexer proxy for PVR apps
- search across multiple torrent and usenet indexers
- add custom indexer definitions with Cardigann YML
- track indexer health, history, and statistics
- run indexers behind SOCKS or FlareSolverr proxies

## When to choose
- you use multiple *arr PVR apps and want centralized indexer management
- you want one place to configure, monitor, and search all your trackers and indexers
- you need support for hundreds of trackers plus generic Newznab/Torznab indexers

## When to avoid
- you only use a single PVR app and don't mind per-app indexer setup
- you need a general-purpose torrent search client rather than an indexer manager
- you want a lightweight tool without a web UI or .NET runtime
