## What it is
Jackett is a self-hosted proxy server that translates queries from media automation apps (Sonarr, Radarr, Lidarr, etc.) into tracker-site-specific HTTP queries for hundreds of torrent trackers. It parses HTML or JSON responses and returns normalized Torznab/Newznab results, also exposing recent uploads as RSS-like feeds.

## Use cases
- connect Sonarr or Radarr to private torrent trackers
- unify search across many torrent indexers via one API
- add Torznab indexer support to apps that lack it
- scrape tracker search results that only offer HTML pages
- serve recent torrent uploads as RSS feeds to download clients
- run a central indexer proxy for a self-hosted media stack

## When to choose
- you use PVR apps like Sonarr, Radarr, Lidarr, or SickRage with torrent trackers
- you need a normalized Torznab/Newznab API in front of many tracker sites
- you want a self-hosted, Docker-friendly indexer proxy with broad tracker coverage

## When to avoid
- you only use Usenet indexers and want native Newznab aggregation (consider NZBHydra2)
- you want a modern successor with built-in indexer sync (Prowlarr)
- you need a general-purpose web scraper unrelated to torrent trackers
