Open Source JavaScript BitTorrent Clients

Rats Search is a cross-platform search tool for torrent indexing across multiple BitTorrent DHT networks. It provides a GUI for searching decentralized torrent metadata in real time without relying on centralized indexes. Built with Electron and Vue.js, Rats Search emphasizes decentralization and anonymity, allowing users to explore content from distributed sources such as the BitTorrent Mainline DHT and WebTorrent. It supports filtering, magnet link generation, and acts as a privacy-conscious alternative to torrent search engines.

Motrix is a full-featured, cross-platform download manager that supports downloading HTTP, FTP, BitTorrent, Magnet, Baidu Net Disk and more.

It emphasizes responsiveness, privacy, and modularity while supporting a growing plugin ecosystem to expand content sources and features.

Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect.

A self-hosted, open-source BitTorrent tracker written in Node.js, allowing users to run their own torrent tracking server.

peerflix is a Node.js-based streaming torrent client that lets you stream video or audio files directly from a torrent (magnet link or .torrent file), without needing to wait for the entire download to finish. It spins up a small HTTP server that serves the torrent’s content as it’s downloaded; for example, if you point a media player (like VLC or MPV) to the provided URL, it will start playing almost immediately. Peerflix automatically selects the largest file in a multi-file torrent by default (or can list all files for manual selection), and supports passing arbitrary flags to the media player — letting you stream with subtitles, full-screen mode, or other player-specific options. Because it's built on the torrent peer network, it downloads pieces on demand as playback proceeds, which can be more efficient if you only want to watch a single file. Peerflix also exposes programmatic API usage using underlying low-level torrent-streaming logic.

Torrent-stream is a core library that underpins peerflix (and similar tools), providing low-level torrent downloading and streaming capabilities in Node.js. It handles connecting to the BitTorrent swarm, negotiating peer connections, fetching torrent pieces, and exposing individual files inside a torrent as streams. This enables developers to build custom torrent-based applications — not just streaming video, but also file downloaders, partial-download managers, or peer-to-peer file distribution tools. The library supports selecting which files to download (useful in multi-file torrents), serves requested pieces on demand, and allows streaming large files without fully writing them to disk upfront — ideal for memory-efficient or on-the-fly consumption contexts. Because torrent-stream is a plain Node.js module, you can embed it in any JavaScript-based backend or tool, integrate it with HTTP servers to serve torrent content, or combine it with other processing pipelines.

WebTorrent is a streaming torrent client for node.js and the browser. YEP, THAT'S RIGHT. THE BROWSER. It's written completely in JavaScript – the language of the web – so the same code works in both runtimes. In node.js, this module is a simple torrent client, using TCP and UDP to talk to other torrent clients. In the browser, WebTorrent uses WebRTC (data channels) for peer-to-peer transport. It can be used without browser plugins, extensions, or installations. It's Just JavaScript™. Note: WebTorrent does not support UDP/TCP peers in browser. To make BitTorrent work over WebRTC (which is the only P2P transport that works on the web) we made some protocol changes. Therefore, a browser-based WebTorrent client or "web peer" can only connect to other clients that support WebTorrent/WebRTC.

WebTorrent CLI is a command-line interface for the WebTorrent protocol, enabling users to stream, download, and seed torrents directly from the terminal using Node.js. It supports both traditional BitTorrent and WebTorrent peers, bridging the gap between desktop clients and browser-based peers. With a simple and intuitive interface, WebTorrent CLI allows users to instantly stream videos (especially with built-in support for VLC, MPV, and Chromecast), making it ideal for media consumption without waiting for full downloads. It’s a handy tool for developers, media sharers, or anyone who wants quick torrent access without a GUI.

bittorrent-dht is a Node.js implementation of the BitTorrent Mainline Distributed Hash Table (DHT) protocol, enabling decentralized peer discovery for BitTorrent clients. This module allows users to announce and lookup peers for specific torrents without the need for trackers. It’s lightweight, fast, and well-suited for building custom torrent clients, browser-based peers, or decentralized apps. This project powers part of WebTorrent and is maintained with performance and minimalism in mind.
