Best Jellyfin Windows Client in 2026: JMP vs FluentFin vs Delfin (+ macOS & Linux)

Best Jellyfin Windows Client in 2026: JMP vs FluentFin vs Delfin

Best Jellyfin Client for Windows in 2026

Looking for the best Jellyfin client on Windows? Jellyfin Media Player (JMP) is the top pick for maximum codec support and HDR passthrough. FluentFin is the modern alternative with a native WinUI 3 interface. Both are free, open source, and connect to any Jellyfin server. This guide compares every Windows, macOS, and Linux client available in 2026.

Best Jellyfin Desktop Clients in 2026: Windows, macOS & Linux

Watching Jellyfin on a desktop or laptop is one of the most common use cases - yet choosing the right client is surprisingly confusing. The official web interface works but lacks codec support. Jellyfin Media Player is powerful but feels dated. FluentFin looks modern but is still in beta.

This guide compares every desktop client available in 2026 and tells you which one to use based on your OS and priorities.

Quick Recommendation

Jellyfin Media Player (JMP) - The All-Rounder

Platforms: Windows, macOS, Linux Status: Official, stable Price: Free, open source

Jellyfin Media Player combines the Jellyfin web interface with MPV as the playback engine. This gives you dramatically better codec support than any browser.

Why JMP is the default recommendation

• Codec support: H.264, H.265/HEVC, AV1, VP9, MPEG-2, VC-1 - virtually everything Direct Plays
• HDR passthrough: On Windows with HDR-capable displays, JMP passes HDR10 metadata to the OS
• Hardware decoding: Uses your GPU for smooth 4K playback at minimal CPU cost
• Keyboard shortcuts: Space (play/pause), Left/Right (seek), F (fullscreen), M (mute)
• Subtitle rendering: Full ASS/SSA styling support via libass

Installation

Windows: Download from jellyfin.org/downloads → Jellyfin Media Player

macOS: Download the .dmg from the same page

Linux (Flatpak - recommended):

flatpak install flathub com.github.iwalton3.jellyfin-media-player

HDR on Windows

For HDR to work in JMP on Windows:

1. Enable HDR in Windows Settings → Display → HDR
2. In JMP settings, ensure Hardware Decoding is enabled
3. Play an HDR10 file - Windows should switch to HDR mode automatically

Note: HDR passthrough requires Windows 10/11 with a compatible GPU and display. JMP does not support Dolby Vision on Windows - it falls back to HDR10.

Limitations

• UI is the Jellyfin web interface embedded in a window - not a native desktop app
• No offline download support
• The project is transitioning to Jellyfin Desktop (Qt 6) - see below

Jellyfin Desktop - The Next Generation (In Development)

Jellyfin Desktop is the official successor to JMP, migrated from Qt 5 to Qt 6. As of April 2026:

• Available on Flathub (Linux) and Arch AUR
• Windows and macOS stable builds are not yet available
• Same MPV backend, modernized framework

If you are on Linux, Jellyfin Desktop is worth trying. On Windows and macOS, stick with JMP until stable builds ship.

FluentFin - Native Windows Experience (Beta)

Platform: Windows only Status: Beta, active development Price: Free, open source

FluentFin is built with WinUI 3 - Microsoft's modern UI framework. It looks and feels like a native Windows 11 app, with Fluent Design, Mica materials, and smooth animations.

Why FluentFin stands out

• Native Windows UI - not a web view, not Electron, genuine WinUI 3
• Modern design - follows Windows 11 design language
• Fast startup - lighter than JMP
• Active development - frequent updates on GitHub

Installation

Download from github.com/insomniachi/FluentFin → Releases

Or install via winget (if available):

winget install FluentFin

Limitations

• Beta - expect occasional bugs and missing features
• Codec support depends on Windows' built-in decoders (install HEVC Video Extensions from Microsoft Store for H.265)
• HDR support is improving but not as mature as JMP
• Windows only - no macOS or Linux

Who should use FluentFin?

Windows users who prioritize a modern, native-feeling UI over maximum codec compatibility. If you watch mostly H.264/H.265 content and want the best-looking Windows app, FluentFin is excellent.

Delfin - Native Linux Client (Beta)

Platform: Linux Status: Beta, active development Price: Free, open source

Delfin is built with GTK4 and libadwaita - it follows GNOME design guidelines and feels right at home on GNOME desktops.

Installation

flatpak install flathub cafe.avery.Delfin

Why Delfin for Linux users

• Native GNOME integration - adaptive layout, dark mode, system fonts
• GStreamer backend - good codec support on Linux
• Lightweight - fast startup, low memory usage
• Flatpak - sandboxed, easy to install and update

Limitations

• Beta - some features still in development
• GNOME-focused - may look out of place on KDE or other DEs
• HDR support depends on your compositor and display setup

tsukimi - Rust + GTK4 (Beta)

Platform: Linux, Windows Status: Beta Price: Free, open source

Built with GTK4 and Rust, tsukimi is fast and lightweight. Good option for Linux users who want a non-GNOME-specific GTK4 client.

Blink - Cross-Platform Flutter Client (Beta)

Platform: Windows, macOS, Linux Status: Beta Price: Free, open source

Blink uses Flutter for a consistent cross-platform experience. The UI is clean and modern, though Flutter apps can feel slightly non-native on each platform.

Rodel Player - Windows Store App

Platform: Windows Status: Stable Price: Free (closed source)

Available on the Microsoft Store. Clean interface, easy to install, but closed-source and less customizable than open-source alternatives.

Jellyfin Web (Browser) - Zero Install

The built-in web interface works in any modern browser - no installation required.

When to use the browser

• Quick access on a shared computer
• Testing your server setup
• Platforms where no native client exists

Browser limitations

The browser cannot Direct Play H.265 on most setups - your server transcodes it, wasting CPU. This is the main reason to use a dedicated client.

Desktop Client Comparison Table

Infuse on macOS - The Premium Option

For macOS users, Infuse by Firecore is the best Jellyfin client available:

• Stunning native macOS interface
• Full Dolby Vision and HDR10 support
• Excellent codec support (virtually everything Direct Plays)
• AirPlay to Apple TV
• Offline downloads

Requires Infuse Pro (~$9.99/year) for full Jellyfin integration. Worth it for Apple users.

Music Desktop Clients

If you use Jellyfin for music, dedicated music clients offer a better experience:
