## What it is
Ttorrent is a pure-Java implementation of the BitTorrent protocol providing a tracker, a download client, and torrent metainfo file creation/parsing. It is designed to be embedded into larger applications, though its components can also run standalone.

## Use cases
- embed BitTorrent-based file distribution in a Java application
- run a BitTorrent tracker in Java
- create and parse .torrent metainfo files
- distribute build artifacts to many machines efficiently
- download torrents programmatically from Java

## When to choose
- you need a simple, embeddable Java BitTorrent library without fancy protocol extensions
- you want both client and tracker functionality in one library
- you need to distribute files to many machines over a datacenter network

## When to avoid
- you need a full-featured end-user torrent client with a GUI
- you require advanced protocol extensions like DHT, magnet links, or encryption
- you are not working on the JVM

## Facets
- artifact type: library
- maturity: active
- function: p2p, networking, file-system, serialization
- domain: networking, files, developer-tools
- platform: jvm, cross-platform
- tags: bittorrent, torrent-tracker, torrent-client, metainfo, p2p-file-sharing
