## What it is
Jellyfin is a free, open-source media system for managing and streaming personal media collections from a dedicated server to end-user devices. It is a community-driven fork of Emby 3.5.2, built on .NET, with no premium features or licenses.

## Use cases
- self-host a media server to stream movies and TV shows
- replace Plex or Emby without paid subscriptions
- organize a personal music, movie, and photo library
- stream media to Android TV, Kodi, or web browsers
- run a home media server in Docker
- share media with family across multiple devices

## When to choose
- you want a fully free, open-source media server with no premium tiers
- you need cross-platform clients (web, Android, iOS, TV apps)
- you want full control and self-hosting of your media
- you prefer a community-governed project over proprietary software

## When to avoid
- you need official commercial support or SLAs
- you require advanced features only available in paid Plex Pass
- you want a zero-configuration hosted cloud service

## Facets
- artifact type: application
- maturity: active
- function: http-server, streaming
- domain: media, self-hosted, web-development
- platform: cross-platform, windows, self-hosted, browser
- tags: media-server, plex-alternative, emby-fork, home-theater, transcoding, dotnet, csharp, linux, macos, docker, android, ios
