Rain is a high-performance BitTorrent client and embeddable Go library, running in production at put.io. It supports core BitTorrent BEPs including DHT, magnet links, UDP trackers, PEX, and encryption, with a client-server architecture exposing a JSON-RPC API and console UI.

Use cases

  • download torrents from magnet links in Go
  • embed a BitTorrent client in my application
  • create and parse .torrent files
  • run a headless torrent server with RPC control
  • stream downloads sequentially while downloading
  • add torrent support to a self-hosted service

When to choose

  • you need a programmable BitTorrent client or library in Go
  • you want a lightweight headless torrent daemon with JSON-RPC control
  • you need DHT, magnet links, and tracker support without a GUI

When to avoid

  • you want a full-featured graphical torrent client like qBittorrent
  • you need a torrent client in a language other than Go
