Jellyfin MonWUI Plugin, displayed in Jellyfin as JMSFusion, is an all-in-one frontend enhancement layer built around a modular slider system located in Resources/slider/.
Rather than applying a single visual modification, JMSFusion expands the Jellyfin Web experience across home screen presentation, metadata, hover interactions, profile management, music playback, pause behavior, library discovery, notifications, and centralized UI configuration.
The project was designed to make Jellyfin feel more polished, personal, and cinematic while keeping the interface cohesive.
JMSFusion works by injecting JavaScript and CSS into the Jellyfin Web UI.
-
Web browsers using Jellyfin Web
-
Mobile clients that embed the Jellyfin Web interface, including:
- Jellyfin for Android
- Jellyfin for iOS
- Jellyfin for Android TV
- Native TV clients that do not load the server's
jellyfin-webfrontend - Other clients using an independent native interface
In short, if a client does not render the server's /web/index.html, JMSFusion cannot modify its interface.
Because the project is archived, compatibility with newer Jellyfin server or client releases is not guaranteed.
