While Kodi excels in customization, it trails Plex in seamlessly sharing media libraries across devices. Plex requires just an app install and login; Kodi demands more setup. The good news? It's entirely achievable.
There are two main methods: Emby (the straightforward option) or MySQL (the advanced one). We'll focus on Emby here, as it's the most user-friendly for reliable syncing, including watch status across devices.
Emby, an open-source media server blending Kodi's flexibility with Plex's client-server model, is the simplest way to share your Kodi library across devices.
To get started, install the Emby server, add key plugins, and integrate the Emby addon into Kodi.
Begin by downloading Emby from the official website's Download section.

Enable Download artwork and metadata from the internet and Save artwork and metadata into media folders for best results—users report smoother Kodi integration with these options.

Click OK, then Next. On the Remote access screen, check Allow remote connections to this Emby server for access outside your home network. Proceed, accept terms, and finish setup.
