It's using third-party APIs for the .torrent content and search engines for content.

But it doesn't even need that. You can use a .torrent or magnet URL from anywhere on the latest builds.

Just drag-n-drop a .torrent file onto the UI or simply paste (Ctrl-V / Cmd-V) a magnet URL that you already had on your clipboard and it will gladly attempt to live stream any arbitrary torrent.

The built-in video player generally works the best with .mp4 video files, but I've seen it successfully stream other media types as well.

When the torrent file in question contains multiple media files, a file chooser dialog appears letting you select which one you wish to watch.

The application could literally be re-written at any time to use any torrent site for showing content.

.. and since it's open source, the genie is out of the bottle.
