## Introduction
WebTorrent is a JavaScript torrent client that runs in both Node.js and web browsers. It bridges the BitTorrent protocol with WebRTC, allowing true peer-to-peer file transfer directly in the browser without plugins. On the desktop, it also connects to traditional BitTorrent peers.

## What WebTorrent Does
- Downloads and streams torrents in real time without waiting for full download completion
- Operates in the browser using WebRTC for peer-to-peer connections without server relay
- Connects to both WebRTC peers (browsers) and standard TCP/UDP BitTorrent peers (desktop)
- Provides a programmatic API for embedding torrent functionality into web and Node.js apps
- Includes a standalone desktop app and CLI for direct torrent downloading and streaming

## Architecture Overview
WebTorrent implements the BitTorrent protocol in JavaScript with an abstraction layer that swaps TCP/UDP sockets for WebRTC data channels in browser environments. The desktop client uses standard libtorrent-compatible networking while the browser client discovers peers through WebSocket-based WebTorrent trackers. Both environments share the same high-level API, so applications work cross-platform with minimal changes.

## Self-Hosting & Configuration
- Install the CLI globally via npm for quick command-line torrent operations
- Use the JavaScript library in Node.js or browser projects with a simple require/import
- Configure options like download path, upload ratio limits, and peer connection caps
- WebTorrent Desktop is available as a standalone Electron app for Windows, macOS, and Linux
- Run your own WebTorrent tracker using the companion webtorrent-tracker package

## Key Features
- True browser-based torrenting without any plugins or extensions
- Streaming-first design that begins media playback before the download finishes
- Dual-network support connecting WebRTC and traditional BitTorrent peers on desktop
- Lightweight API suitable for embedding in web applications and services
- MIT-licensed with an active open-source community

## Comparison with Similar Tools
- **qBittorrent** — full-featured desktop client; WebTorrent focuses on streaming and browser integration
- **Transmission** — lightweight daemon; WebTorrent adds browser and WebRTC support
- **aria2** — multi-protocol downloader; WebTorrent is torrent-specific with streaming focus

## FAQ
**Q: Can WebTorrent download from regular BitTorrent peers in the browser?**
A: No. Browsers can only connect to WebRTC peers. The desktop client connects to both WebRTC and standard BitTorrent peers.

**Q: Is streaming supported for all file types?**
A: Video and audio files can be streamed. Other file types download normally.

**Q: Does WebTorrent require a central server?**
A: A lightweight tracker helps peers find each other, but the actual data transfer is fully peer-to-peer.

**Q: Is it legal to use WebTorrent?**
A: WebTorrent is a protocol tool. Legality depends on the content being shared, not the tool itself.
