# Jellyfin

Jellyfin is a free and open-source media server and suite of multimedia applications designed to organize, manage, and share digital media files to networked devices. Jellyfin consists of a server application installed on a machine running Microsoft Windows, macOS, Linux or in a Docker container, and another application running on a client device such as a smartphone, tablet, smart TV, streaming media player, game console or in a web browser. Jellyfin also can serve media to DLNA and Chromecast-enabled devices. It is a fork of Emby.

## Features

Jellyfin follows a client–server model that allows for multiple users and clients to connect and stream digital media remotely. Because Jellyfin runs as a fully self-contained server, there is no subscription-based consumption model that exists, and Jellyfin does not utilize an external connection nor third-party authentication for this functionality. This enables Jellyfin to work on an isolated intranet in much the same fashion as it does over the Internet. Because it shares a heritage with Emby, some clients for that platform are unofficially compatible with Jellyfin; however, as Jellyfin's codebase diverges from Emby, this becomes less possible. Jellyfin does not support a direct migration path from Emby.
Jellyfin is extensible, and optional third-party plugins exist to provide additional feature functionality. The project hosts an official repository, however plugins need not be hosted in the official repository to be installable.
Version 10.6.0 of the server software introduced a feature known as "SyncPlay", which provides functionality for multiple users to consume media content together in a synchronized fashion. Support to read epub-format ebooks with Jellyfin was also added. Support for third-party plugin repositories was also added, allowing users to create and install plugins without the need for the official plugin repository. The web front end has been split off in a separate system in anticipation of the move towards a SQL backend and High Availability with multiple servers.

## Development

The project began on December 8, 2018, when co-founders Andrew Rabert and Joshua Boniface, among other users, agreed to fork Emby as a direct reaction to closing of open-source development on that project. A reference to streaming, Jellyfin's name was conceived of by Rabert the following day. An initial release was made available on December 30, 2018.
