To add to everyone else, I moved from Kodi to Jellyfin and it was a game changer for my home server solution. (I run the server off of my gaming PC)

If you’re a real nerd about it and can get in BakaBt has crazy big full books. Manga and light novels. We’re taking Gigabytes for single volumes… They look very nice though.

Otherwise Tachiyomi is great and usually the stuff online is high enough quality to satisfy me and had kept me from running my own Ubookquity server.
