## What it is
cross-seed is a Node.js application that automatically finds and downloads torrents matching your existing torrent library across multiple trackers via Torznab indexers, enabling cross-seeding without re-downloading data. It runs as a daemon or CLI, integrates with qBittorrent, rTorrent, Deluge, and Transmission, and supports features like partial matching, data-based matching, and linking for renamed files.

## Use cases
- automatically cross-seed my existing torrents on other private trackers
- build upload ratio without downloading new data
- find torrents on other trackers that match my media library
- seed the same torrent on multiple trackers automatically
- rescue and re-seed a torrent library with renamed files
- monitor for new uploads matching my existing downloads
- enter new torrent swarms as a full seeder instantly

## When to choose
- you use private trackers and want to build ratio by cross-seeding
- you want fully automatic background matching of your torrent library across trackers
- you use Torznab-capable indexers via Prowlarr or Jackett
- your torrent client is qBittorrent, rTorrent, Deluge, or Transmission
- you want to strengthen swarms and improve torrent availability

## When to avoid
- you only use public trackers, where cross-seeding is less effective
- you need a GUI-first torrent management tool rather than a background service
- you cannot run a Node.js daemon or Docker container alongside your torrent client
- you want a general-purpose torrent search or download manager
