## Introduction
Prowlarr is an indexer manager and proxy that centralizes the configuration of search indexers for the entire *arr stack. Instead of configuring indexers separately in Sonarr, Radarr, and Lidarr, you set them up once in Prowlarr and it syncs them automatically.

## What Prowlarr Does
- Manages Usenet and torrent indexer configurations in a single dashboard
- Syncs indexer settings automatically to Sonarr, Radarr, Lidarr, and Readarr
- Proxies search requests through a unified API with standardized results
- Tests indexer health and reports connectivity or authentication issues
- Tracks indexer statistics including query counts and response times

## Architecture Overview
Prowlarr is a .NET application with an Angular frontend, following the same architecture as other *arr applications. It stores configuration in an SQLite database and communicates with downstream *arr apps via their APIs. Indexer definitions are maintained as YAML schemas that map each indexer's search and result format to the Newznab or Torznab standard.

## Self-Hosting & Configuration
- Deploy via Docker: `docker run -d -p 9696:9696 linuxserver/prowlarr`
- Add indexers through the web UI with credentials and API keys
- Connect downstream apps (Sonarr, Radarr) via Settings > Apps with their URLs and API keys
- Configure sync profiles to control which indexers map to which apps
- Set up Flaresolverr for indexers behind Cloudflare protection

## Key Features
- One-time indexer setup that syncs across all connected *arr applications
- Support for 500+ indexers via built-in Cardigann definitions
- Search directly from the Prowlarr UI across all configured indexers at once
- Automatic indexer health monitoring with alerts for failures
- Tag-based filtering to assign specific indexers to specific apps or categories

## Comparison with Similar Tools
- **Jackett** — The predecessor indexer proxy; Prowlarr adds native *arr app sync and a more polished UI
- **NZBHydra 2** — Usenet-focused meta-searcher; Prowlarr handles both Usenet and torrent indexers
- **Manual indexer config** — Configuring each *arr app individually; Prowlarr centralizes and syncs everything
- **Cardigann** — YAML-based indexer definitions; Prowlarr includes Cardigann support natively
- **FlexGet** — Plugin-based automation; Prowlarr focuses specifically on indexer management

## FAQ
**Q: Does Prowlarr replace Jackett?**
A: For *arr users, yes. Prowlarr provides the same indexer proxy functionality with added automatic sync to Sonarr, Radarr, and other *arr apps.

**Q: Can I use Prowlarr without Sonarr or Radarr?**
A: Yes. You can use Prowlarr standalone as an indexer search tool, but its primary value is the automatic sync with *arr applications.

**Q: How do I add a custom indexer?**
A: Prowlarr supports custom Cardigann YAML definitions. Add your definition file to the indexer definitions folder and restart.

**Q: Does Prowlarr support Flaresolverr?**
A: Yes. Configure Flaresolverr as an indexer proxy in Settings > Indexers > Add > Flaresolverr for sites behind Cloudflare challenges.
