That said, it might be worth looking into Stremio and Debride. I've been seeing that pop up lately and it's mostly torrent based.
Just a correction on this point. With a debrid service, it's not actually torrent-based – not in the sense that at any point you'd be utilising any p2p traffic/mechanisms. It relies on torrenting activity in a different sense, in that what you download is encrypted DDL files from the debrid provider's central cache, whose origin is in torrents. And if there's no files meeting your search query stored already in the cache, but which are available through public trackers, then you'd request the service downloads the torrent to its cache. So at no point are you accessing peers. Worth noting that afaik, this is all for public trackers, not private.
