WebTorrent

WebTorrent is a peer-to-peer (P2P) streaming torrent client written completely in JavaScript by Feross Aboukhadijeh (who also created YouTube Instant), John Hiesey, and the team at WebTorrent and on GitHub, for use in web browsers, as well as a WebTorrent Desktop stand alone version able to bridge WebTorrent and BitTorrent serverless networks... A goal of WebTorrent is to maintain compatibility with BitTorrent as much as possible. WebTorrent uses the same protocol as BitTorrent but uses a different transport. BitTorrent uses TCP connections and UDP packets that currently don't work on the web for security reasons, while WebTorrent uses WebRTC facilitating peer-to-peer connectivity and functions on the web as the only option to avoid using servers (ie. web sockets and middlemen servers, etc). https://en.wikipedia.org/wiki/WebTorrent
