Overview

WebTorrent is a free streaming torrent client for browsers and desktop, with a developer API for Node.js and the web. Audio or video can start playing before a download completes, while seeking fetches the required pieces as playback moves. The browser client supports video, audio, images, PDFs, HTML, and other content, subject to browser support. It is written in JavaScript and uses WebRTC for peer-to-peer transport in browsers. Developers can install it with npm and use it with Browserify or Webpack. WebTorrent Desktop connects to BitTorrent and WebTorrent peers, including Transmission, uTorrent, and instant.io. The project describes itself as non-profit, open-source software under the MIT License, and its plans are listed as free and non-commercial. It runs on web, macOS, Windows, and Linux. Browser clients have a specific constraint: they can download only torrents seeded by a WebRTC-capable client. Live streaming is not provided out of the box, though a live-streaming solution can be built on top of WebTorrent. The project offers support through Discord, GitHub discussions, and issue reporting.

Who it is for

It suits users who want torrent-based playback to begin before a file finishes downloading, as well as developers seeking a browser and Node.js API. Browser users need torrents seeded by a WebRTC-capable client.

What is good

Free and open source under the MIT License
Playback can start before downloads finish
Runs on web, macOS, Windows, and Linux
Developer API works in Node.js and the web

What to know first

Browser downloads require a WebRTC-capable seeder
Live streaming is not provided out of the box
Listed plans are non-commercial

Verdict

WebTorrent combines streaming playback with browser and desktop torrent clients, plus a shared web and Node.js API. Its browser seeder requirement and lack of built-in live streaming are important limitations to weigh.
