Development

Jellyfin is open-source and released under the GPL-2.0 license. The software was developed as a fork of Emby after it changed to a closed-source model.  Jellyfin is made available for Docker through the efforts of LinuxServer.io and their commitment to simplifying self-hosting.

You can learn more about how to contribute to Jellyfin through their website.  The Jellyfin development team also accepts sponsorships.
