Karaoke Mugen vs UltraStar Deluxe

Karaoke Mugen is a free, open-source playlist manager for karaoke parties, available for Windows, macOS, and Linux. Operators can add, remove, reorder, shuffle, import, and export songs, while guests can suggest tracks from their own devices. Operators can enable voting, set song or singing-time quotas, and filter songs with blacklists and whitelists; sessions can also use automixes and quiz mode. The player includes playback controls, automatic volume adjustment, pitch and speed changes, and a synchronized second video player. It accepts video formats supported by mpv, uses ASS subtitles, and can import formats including Ultrastar, Karafun, and KBP. Once installed, configured, and up to date, it can run without an internet connection, but guests need the same Wi-Fi network. The software is published under the MIT license and provides a WebSockets API for additional interfaces or clients. Linux binaries require GLIBC 2.31 or higher; the Windows portable version must be updated by replacing files from a new ZIP archive.

UltraStar Deluxe is a free, open-source karaoke game for Windows, Linux and macOS. Players sing and score points based on pitch and rhythm, and 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 and download community plugins, free songs and code patches. Lua plugins are supported, with the .usdx extension and placement in the plugins directory required. The Official UltraStar Song Format is shared with partner games and song editors. Listed minimum requirements include a 1GHz CPU, OpenGL 1.2, 512MB free RAM and 200MB disk space, plus room for songs and videos. The downloads page lists version 2026.9.0 and links to an installer, release notes and source; Flathub and AUR are alternative installation methods. Audio devices do not have plug-and-play support, so the game must be restarted after a new device is connected.
