I’ve always been conservative about what kind of services I host because it takes time to get them set up. For example, there’s no reason for me to set up music streaming when I only ever listen to music on my phone and all my music files are already on my phone. On the other hand, it’s a good learning opportunity to set stuff up and have to fix it when it breaks. What do you think?
If something interests you, set it up. If you find you don’t need it, take it down.
That’s pretty much exactly what I have done. I’ve hosted Plex, and Matrix in the past. Plex I will host in the future but Matrix was too much for me to host on my own, but the experience of setting it up myself was definitely worth it.
I recommend checking out Jellyfin instead of Plex. Open source, fully self hosted.
