Jellyfin

Jellyfin is a free and open-source media server software that organizes, stores, and streams personal media libraries to various devices. It runs as a server on a host and serves clients over a network.

It originated in 2018 as a community fork of Emby after Emby changed its licensing; Jellyfin is maintained by volunteers and the wider community, emphasizing user freedom and privacy.

Features include automatic metadata scraping for movies, TV, and music; on-the-fly transcoding with FFmpeg; support for multiple streaming protocols; Live TV and DVR functionality; parental controls; and extensive plugins to extend functionality.

Platform and clients: cross-platform server that runs on Windows, Linux, macOS, Docker, and ARM devices; clients include web browser interface, mobile apps for iOS and Android, smart TVs, streaming devices, and Kodi plug-in; supports offline access via transcoding caches.

Privacy and licensing: self-hosted, designed to avoid data collection by vendors; released under an open-source license and developed by a community of volunteers.
