Arlet

An unofficial Apple Music client for Windows 10 and 11: a fast, native-feeling desktop app built with Tauri v2, Rust, and MusicKit. Arlet is in alpha development.

_{Windows 10 22H2 or newer. All releases and signatures}

Features

• Your Apple Music library on the Windows desktop: recently added, recently played, artists, albums, songs, and playlists with folders, cached for a fast start.
• Home and Browse: recently played playlists, heavy rotation, personal recommendations, Apple Music charts, and radio stations.
• Search the full Apple Music catalog or just your library.
• Playlists: create playlists and folders, add songs, and pin favorites to the sidebar.
• Queue control: play now, play next, play later, shuffle, and repeat.
• Built for Windows: media keys and the Windows media overlay, light and dark themes, and Mica or Acrylic window materials.
• Automatic, signed updates on a stable or beta channel. Installers are Authenticode-signed and GPG-signed.

Install

1. Download the installer for your PC above (x64 for most PCs, Arm64 for Snapdragon and other Arm devices).
2. Run it. Arlet installs for your user account only, no administrator rights needed.
