Karaoke Mugen vs Vocaluxe

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.

Vocaluxe is a free, open source singing game for up to six players. Participants sing into microphones and receive scores based on pitch and rhythm, using songs in the UltraStar format. Players can create tracks, sing duets with different notes, or use medley mode for shortened song selections. Party options include challenge mode and Tic-Tac-Toe. Profiles can contain pictures and appear in high-score lists, with webcams available for taking profile photos. Lyrics support multi-screen display. Controls include keyboard, mouse, gamepads, WiiMotes, and smartphones. The Free plan costs nothing and includes up to six players; there is no free trial. Portable versions are provided for releases. Vocaluxe is listed for Linux, web, and Windows, but Linux users must compile it themselves and the maker says Linux has no official support. Help is available through the community Discord and GitHub wiki. The project wiki says there are currently no active developers.
