Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

For the past year or so, I have been fairly happy with the RD, Torrentio, and Stremio setup. I've enjoyed being able to have a mostly seamless streaming experience; just search, click, and watch with little load or wait. In the past, I've experimented with the -arr's and qTorrent setup on a local machine, but I switched to RD for the convenience of being able to spontaneously watch a show or movie (like on a date night).

With the possible (maybe likely) end of RD, I have wanted to look back again at having a personal setup, but I want to see if anyone has recommendations for a setup that is as close as possible to the current one. I know, of course, that a local setup will not have the same benefit as a massive service as RD with a huge cache of torrents ready to go, but is there a way to get close? Round off some of the sharp edges and pain points?
