Jellyfin
A free software media system for managing and streaming your media from a dedicated server to multiple devices.
What is Jellyfin?
Jellyfin is a free software media system that allows you to manage and stream your personal media collection from a dedicated server to various devices. It solves the problem of accessing your media library across different platforms without relying on proprietary services or paying subscription fees. The system provides a server backend and API that client applications can connect to for playback and library management.
Users who want to self-host their media library and stream it to multiple devices, including home theater enthusiasts, privacy-conscious individuals, and those seeking an open-source alternative to commercial media servers.
Developers choose Jellyfin because it offers complete control over their media with no licensing costs or feature restrictions. Its open-source nature and active community ensure transparency, customizability, and freedom from vendor lock-in compared to proprietary alternatives.
