I think things like "front it with a reverse proxy" is the stuff OP doesn't understand or want to learn.
Stremio is install, stream. No hosting of own content (and as this thread points out OP probably dosnt have any), no proxy, no downloading and setting up a seperate arr stack.
Put it this way, my 14yr old cousin has Stremio its that simple. While they could install Jellyfin I doubt they could setup and run all the other requirements to obtain and watch media as easily.
