I can +1 for Stremio+Debrid (RealDebrid is just one provider for those that haven't dove in)

I would argue this is one case where FOSS shouldn't be priority #1, unless you really want to spend the time, effort, and (most importantly in 2026) money to maintain a NAS, in which case the *arr stack + Usenet and Jellyfin are great. But you really can't understate how much of a rabbit hole dealing with the entire thing can be. For the most part, Stremio just works and well enough I can send a guide to normie friends and they could follow along and get it running in like half an hour.

I do a hybrid approach, I own blurays of anything sentimental or low bitrate destroys (think Redline, XFiles (so much low/dim light low bitrate makes it look like a pixelated mess)), have a large collection of older media on my Unraid NAS (typically the Achilles heel of the Stremio/Debrid setup is anything that isn't at least semi popular), and stream the rest w/Stremio. Works out to like $60/yr for Debrid/Usenet. I did just lose an 18tb drive in my NAS which really made me think hard if it was worth continuing with, but for now decided to keep it.
