Jellium Desktop is an unofficial desktop client for Jellyfin, the open-source media server platform.
The tool solves the problem of accessing Jellyfin media libraries from a native desktop application rather than through a web browser. It builds on Chromium Embedded Framework for the user interface and mpv for media playback, combining a web-based frontend with a dedicated video player backend to deliver a desktop experience tailored to local playback.
Jellium Desktop suits users who prefer a native application over browser-based access to their Jellyfin servers and who need cross-platform support. The project provides builds for Linux (AppImage and Flatpak formats, with Arch Linux AUR availability), macOS (both Apple Silicon and Intel), and Windows (x64 and arm64 architectures). This breadth of platform support makes it accessible across different operating systems and hardware configurations.
The project maintains a substantial user base, with almost all open issues coming from outside users rather than the core team, indicating real-world adoption. Maintainers typically respond to new issues and pull requests within a few days. Work in the issue tracker is dominated by bug reports and enhancement requests, with particular focus on Windows-related issues.
