Karaoke Mugen

Karaoke Mugen is a playlist manager for karaoke parties, designed for an operator to organize songs and manage audience participation. Operators can add, remove, reorder, shuffle, import, and export songs, while guests can submit requests from their own devices. An operator can let guests vote on the next song, set song or singing-time quotas, and apply blacklists or whitelists. Sessions can include automixes and quiz mode. The player offers 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. Users can save profiles and favorites online, link AniList, Kitsu, or MyAnimeList accounts for songs from watched anime, and display the current song on Discord. Once installed, configured, and up to date, the app can run without internet; guests must be on the same Wi-Fi network. It is free and open source under the MIT license, with Windows, macOS, and Linux builds. Linux binaries require GLIBC 2.31 or higher.
