Jellyfin is a cross-platform Open Source media system that focuses on the management and control over your streaming media.
It can be utilized as an alternative to the proprietary Emby and Plex to provide media from a dedicated server to end-user devices via multiple apps. Jellyfin is descended from Emby's 3.5.2 release and ported to the .NET Core framework to enable full cross-platform support.
Jellyfin supports most browsers like Chrome for use with Chromecast for server set up. There is an in-depth setup guide available to help you. The goal with Jellyfin is to give you an easy option for organizing and managing all your media files from a central location.
