What is jellyfin-launcher.exe?
jellyfin-launcher.exe is a small utility that starts Jellyfin Desktop Launcher and connects to your Jellyfin server. It provides quick access to your media library by launching the appropriate Jellyfin components and opening your configured server URL in a browser or app window.
This launcher manages startup arguments, optional background tasks, and server discovery. It remains lightweight, avoiding heavy UI until you request Jellyfin content, which helps reduce unnecessary resource use and speeds up initial access.
Quick Fact: Jellyfin Launcher helps decouple the server backend from the desktop experience, enabling faster startup and easier configuration for local or remote Jellyfin servers.

- Server Discovery Process: Detects available Jellyfin servers on the network or configured URLs
- Browser/Client Launcher: Opens the Jellyfin web UI in a browser or embedded view
- Background Helper: Optional background task for keep-alive and session maintenance
- Update Check: Checks for launcher updates and notifies user
