With kodi, real debrid and trakt account, you can go from fresh kodi install to instantly streaming (not hosting) nearly 90% of torrent content available, in about 5 minutes. It's not hard to do and no need to selfhost and setup the "..rr"s.
Edit: changed 10 minutes to 5 minutes once hsve real-debrid and trskt accounts already setup.
There is firefox addon that i just found which does this. It's called: Extract video link. Maybe look at source code.
