If you run your own media server, you've likely weighed up the pros and cons of Kodi and Plex. Normally, you'd run one or the other, but some enterprising developers have fused the two, creating third-party plugins that integrate Plex within the open-source software. As of today, however, there is an official add-on in town.
Plex for Kodi operates like many other video add-ons, adding features that extend the default Kodi experience without impacting existing libraries. It can be linked with the servers you run personally as well as those shared with you and, of course, will play back nearly any video or audio format you can throw at it. It can be found in the official Kodi repository but will only work if you run a Plex server and have a Plex Pass subscription.
In a blog post, Team Kodi member Keith Herrington says that the add-on will be made available to all in time: "The intention is for the Plex for Kodi add-on to be available to everyone as soon as we run out of planned features and don't see any major bugs." Developers are also encouraged to submit their own feature updates, which may be integrated into the official add-on should they prove beneficial to the community.
