WebTorrent Desktop is for streaming torrents. Whether it's video from the Internet Archive, music from Creative Commons, or audiobooks from Librivox, you can play it right away. You don't have to wait for it to finish downloading.
WebTorrent Desktop connects to both BitTorrent and WebTorrent peers. It can talk to peers running Transmission or uTorrent, and it can also talk to web pages like instant.io.
WebTorrent Desktop is in beta. We think it's pretty sweet, but we're still working on it. Try it out and let us know what you think!
It's also 100% open source. All the source code is on Github. If you run into a bug, please tell us about it by creating an issue.
