Jellyfin Hosting

How Jellyfin works

Jellyfin scans media folders and presents their contents as organised libraries for films, television, music, and other supported collections. Metadata and artwork make a large folder tree easier to browse, while server users can open the library through a browser or compatible client application. The server remains the central source for playback state, users, and library organisation.

Playback can happen through direct play when a client understands the stored format. When a device cannot handle the container, codec, audio, or subtitles, Jellyfin may remux or transcode the stream. That conversion work is the main reason a media server can consume much more processor capacity during playback than it does while simply browsing a library.

Key Jellyfin features

Libraries separate different media types and audiences, while user accounts can keep viewing activity and access distinct. Client applications connect to the same server, so a household can use televisions, phones, tablets, or browsers without maintaining a separate catalogue for each device.

Jellyfin supports direct playback, direct streaming, and transcoding paths depending on client compatibility. Direct play is the lightest option because the server sends the existing file. Video conversion, especially when subtitles must be burned into the picture, creates a heavier workload and can limit simultaneous streams on a small plan.

Jellyfin vs Plex

Jellyfin is designed around a self-hosted server and a community-developed client ecosystem. Plex also organises personal media, while adding a Plex account layer and optional Plex Pass features. The products can look similar at the library level while following different service and account models.

Plex may suit users who want official applications across many device categories and optional subscription features. Jellyfin is a better fit when control of the server and media catalogue matters more than access to a surrounding proprietary service. Client compatibility should be checked for the devices a household plans to use.

Who uses Jellyfin

Home users run Jellyfin for family film and music libraries. Collectors use it to bring media spread across folders into one searchable interface, while clubs or small communities can create separate accounts for a limited group. It can also serve audio-only collections, though dedicated music servers may offer a more focused experience.

The best results come from media that clients can play directly. A library dominated by formats that require conversion, or several viewers streaming at once, can outgrow an entry configuration even when the stored catalogue itself is modest.

Self-hosting Jellyfin: requirements and cost

For Jellyfin, storage capacity and playback conversion are the two practical limits. The database status is “Not required” in the catalogue mapping, while the media library, artwork, cache, and temporary conversion files occupy plan storage. CPU demand rises when direct play is not possible or several users request converted streams at the same time.

AvaHost maps Jellyfin to Plan 2 at €5, and the software itself is free to run. Because media files dominate capacity, 50 GB on Plan 3 is a realistic first step for a growing library, while 100 GB on Plan 4 better suits a substantial collection. The Jellyfin service includes one-click setup, automatic application updates, scheduled backups, custom-domain support, and automated HTTPS.
