Moonfin-Core

Platform coverage

Moonfin is a cross platform media client built with Flutter for Jellyfin and Emby users. It requires Jellyfin 10.8.0 or newer or Emby 4.8.0.0 or newer for full support, and it runs on Android 6.0 and above including Android TV and Google TV, iOS 16 and above, Apple TV (tvOS 17 and above), macOS 14 (Sonoma) and above, Windows 10 on x64 and ARM64, Linux with GTK 3 and CMake 3.13 (Wayland only), modern browsers as an installable PWA, and experimental Samsung TV on Tizen 6.0 and above. Android TV and Apple TV ship from the same codebase with a TV tuned interface and D pad navigation.

Features

The client offers broad playback support through AetherEngine on iOS, Apple TV and macOS, native Media3 or libmpv on Android and Android TV, libmpv on Windows and Linux, and the browser's own player on web, covering AV1, HEVC, Dolby Vision, Dolby Atmos, HDR10 plus and bitstream audio passthrough. It includes offline downloads in original or transcoded quality with automatic folder organization and offline subtitles, ebooks and audiobooks with EPUB, MOBI, AZW/AZW3, PDF and comic archive reading plus M4B chapter navigation, and in app retro games from a server library via native libretro with gamepad support and synced save states. A multi server unified library merges content from several Jellyfin and Emby servers.

Distribution

Releases are published on GitHub with total download counts and a Google Play listing for the Android TV app. The project links a Discord community and a BuyMeACoffee page. A featured media bar offers Classic, Bookshelf, Gallery and Banner layouts. The codebase is licensed GPL-2.0, and the README notes Dolby Vision Profile 7 direct plays on both Apple and Android TV as a real time conversion rather than a transcode.

Editorial conclusion

Moonfin is GPL-2.0 licensed and reported five hundred ninety stars at indexing, with a Google Play listing for Android TV and a Discord community linked from the README.
