My dude, I understand your unwillingness, but docker is just a fancy new way of saying “install apps without it being a major PITA”. You just find the app you want on docker hub or some other docker repo, you pull the image, you run it, et voila, you have a container. No worrying about python suddenly breaking, or about running 5 commands in a row to spin up an app (I used to do this, including the whole python rain dance, to run home assistant. I feel stupid now).
Decluttarr actually has a section to set up their container:
https://github.com/ManiMatter/decluttarr#method-1-docker
It’s step by step, all you have to do is get docker installed on your machine, then copy paste that text into a file, and run the docker command mentioned in the same directory as the file.
Trust me, you want to learn this, because after the first 15 minutes of confusion, you suddenly have the holy grail to self hosting right at your fingertips. It takes me all of 5 minutes to add a new service to my homelab all because it’s so easy with docker. And it’s so ubiquitous and popular! TrueNAS SCALE uses docker for all its apps, the idea of containers essentially reshaped Linux desktop to be what it is today, with flatpaks and all.
I host a Plex server for close to 70 friends and family members, from multiple parts of the world. I have over 60TBs of movies, tv shows, anime, anime movies, and flac music, and everyone can connect directly to my server via my reverse proxy and my public IPs. This works on their phones, their tvs, their tablets and PCs. I have people of all ages using my server, from very young kids to very old grandparents of friends. I have friends who share their accounts with their families, meaning I probably have already hit 100+ people using my server. Everyone is able to request whatever they want through overseerr with their Plex account, and everything shows up pretty instantly as soon as it is found and downloaded. It works almost flawlessly, whether locally or remotely, from anywhere in the world. I myself don’t even reside in the same home that my Plex server resides. I paid for my lifetime pass over 10 years ago.
Can you guarantee that I can move over to jellyfin and that every single person currently using my Plex server will continue having the same level of experience and quality of life that they’re having with my Plex server currently? Because if you can’t, you just answered your own question. Sometimes we self host things for ourselves and we can deal with some pains, but sometimes we require something that works for more people than just us, and that’s when we have to make compromises. Plex is not perfect, and is actively becoming enshittified, but I can’t simply dump it and replace it with something very much meant for local or single person use rather than actively serving tens to hundreds of people off a server built with OTC components.
