UltraStar Deluxe

What UltraStar Deluxe is

UltraStar Deluxe is a free, open-source karaoke game for Windows, Linux, and macOS. Players sing and earn points based on vocal pitch and rhythm, and they can create their own songs. Party mode supports 8–12 players divided into two or three teams. The maker says more than 10,000 songs are available; players can also use DRM-free audio files or music stored on their computers. SingStar microphones work with the game. Users can create themes or download community plugins, free songs, and code patches. Lua plugins are supported when they use the .usdx extension and are placed in the plugins directory. The game uses the Official UltraStar Song Format, shared with partner games and song editors. Listed minimum requirements include a 1GHz CPU, OpenGL 1.2, 512MB free RAM, and 200MB of disk space, plus room for songs and videos. Flathub and AUR are alternative installation methods. The downloads page lists version 2026.9.0 as current. Audio devices do not have plug-and-play support, so the game must be restarted after connecting a new device.
