Cons
Con Streaming outside of your home is complicated
Unless you enable unPnP which is a security risk, you have to manually port forward or setup a remote server yourself. And unless you know what you're doing, you might open your network to potential hackers. Make sure to read up on reverse proxies or how to set up a vpn with Jellyfin.
Con Some poor clients
The AndroidTV-client is terrible.
Con No free services
It has no free with ads services like Plex.
Con Less features than Emby
Con Slow web interface
For large media libraries, on lower spec hardware (eg SBC), images can take some time to initially load when changing pages/sections (v10.6.4).
Con You may have to jailbreak some devices
This is only for things like a Fire stick, but Android TV boxes etc. should be fine.
Con Terrible navigation
Menus over menus with dozens of submenus.
Con Not Client/Server Capable
While most solutions provide a client/server setup the KODI developers REFUSE to adopt this approach forcing individual setups for every device.
Con Poorly optimized
Often not a fluid experience on low-end devices.
Con No official AAA addons for streaming services
It does not have any official AAA addons and fully relies on the community which result in often broken packages/addons.
