Jellyfin
Jellyfin is a free, open-source media server that lets you organise, stream and access your personal media collection from anywhere.
It lets you store and manage movies, TV shows, music, photos and other media in one place, then stream that content to a wide range of devices through a web interface or compatible apps.
Jellyfin is designed to give users full control over their media without subscriptions, tracking or cloud dependence, making it a popular choice for people who want a private, self-hosted alternative to commercial streaming platforms.
In addition to media playback, Jellyfin offers helpful features such as user accounts, watch history, subtitles, metadata fetching, library organisation and support for multiple clients and devices. It is especially well suited for households, personal media collectors and enthusiasts who want a customisable and privacy-focused way to manage their digital entertainment library.
All of mu media content is stored and played using Jellyfin, especially movies. I tend to use Navidrome for music.
