## What it is
libtorrent is a feature-complete, efficient C++ library implementing the BitTorrent protocol with support for popular extensions including BitTorrent v2, DHT, uTP, and magnet links. It is designed for real-world deployment, scaling from embedded devices to high-performance servers, and includes Python bindings.

## Use cases
- build a bittorrent client in C++
- embed torrent downloading into a desktop application
- add bittorrent support to an embedded device
- download files via magnet links programmatically
- create and seed torrent files from a server
- python bindings for bittorrent downloading

## When to choose
- you need a production-grade, efficient BitTorrent implementation in C++
- you need BitTorrent v2, DHT, and extension protocol support
- you need a library that runs on both embedded devices and servers
- you want Python bindings for torrent functionality

## When to avoid
- you need a ready-to-use end-user torrent client GUI rather than a library
- your project is not C++/Python and lacks bindings for your language
- you only need simple HTTP file downloads without peer-to-peer

## Facets
- artifact type: library
- maturity: stable
- function: p2p, networking, file-system, concurrency
- domain: networking, developer-tools, cross-platform
- platform: windows, cpp, python, cross-platform
- tags: bittorrent, torrent-client, file-sharing, dht, magnet-links, embedded, linux, macos
