Moonfin is an enhanced Jellyfin client built with the Enact/Sandstone framework, optimized for Samsung Smart TVs (Tizen) and LG Smart TVs (webOS). A single shared codebase powers both platforms with native video pipelines tuned for each.
Moonfin builds on the solid foundation of Jellyfin with targeted improvements for the TV viewing experience.
- Samsung AVPlay (Tizen) and Starfish/HTML5 (webOS) native video pipelines
- Smooth playback with proper hardware decoding for H.264, HEVC, HDR10, HLG, and Dolby Vision (where supported)
- Automatic DirectPlay → native transcode → hls.js fallback chain when a format isn't natively supported
- Enhanced player controls optimized for TV remote navigation
- Unified Library Mode — Combine content from all connected Jellyfin servers into a single view
- Browse, search, and play content across multiple servers seamlessly
- Server badges show content origin when unified mode is enabled
- Cross-server playback with proper progress tracking per server
- Favorites, genres, and search aggregate results from all servers
Moonfin is the first smart TV client with native Jellyseerr support.

The easiest way to install on Samsung TVs is using the Jellyfin 2 Samsung tool:
- Download Jellyfin 2 Samsung by @PatrickSt1991
- Enable Developer Mode on your Samsung TV:
- Go to Settings → General → System Manager → Developer Mode
- Turn Developer Mode ON
- Enter your PC's IP address
- Restart the TV
- Run the tool, select the Moonfin
.wgtfile, enter your TV's IP address, and install
- Enable Developer Mode on your LG TV via the LG Developer portal
- Install the webOS CLI tools (
@webos-tools/cli) - Set up your TV as a device:
ares-setup-device - Install the IPK:
ares-install --device <your-tv> moonfin.ipk
Seerr/Jellyseerr integration uses the Moonfin Jellyfin Plugin to proxy requests through your Jellyfin server, avoiding CORS and cookie issues on TV webviews.
- Install the Moonfin Plugin on your Jellyfin server
- Configure the plugin with your Seerr/Jellyseerr server URL and API key in the Jellyfin admin dashboard
- In Moonfin on your TV, go to Settings → PLugin and enable the integration — no additional URL or key entry is needed on the TV side, it connects through your Jellyfin server automatically
Note: The plugin acts as a server-side proxy, so your TV only needs to reach your Jellyfin server. Seerr/Jellyseerr does not need to be directly accessible from the TV.
- Node.js 18+ and npm 9+

This project uses npm workspaces and Enact to share a single React codebase across both platforms while keeping platform-specific code isolated.

Shared code in packages/app/ never imports directly from @enact/webos, tizen.*, or webapis.*. Platform-specific behavior is isolated through runtime detection:
import { isTizen, isWebOS, getPlatform } from './platform';
Services like video, storage, and device profiles use getPlatform() to dynamically import the correct platform implementation at runtime.
- Enact/Sandstone provides TV-optimized UI components and Spotlight navigation
- Tizen: AVPlay API for video,
tizen.tvinputdevicefor remote keys - webOS: Shared HTML5 video element with
audioTracksAPI, Luna service calls for storage - Packaged apps (
.wgt/.ipk) bypass CORS restrictions - Cross-origin cookies don't persist in either platform's webview — use API keys instead
- UI changes should be tested on actual TV hardware when possible
