KaraFun vs Karaoke Mugen

KaraFun is a karaoke service for singing together, with singing battles and music quizzes on Android, iOS, macOS, web, and Windows. Its free plan includes free songs, Premium song previews, access to try features, and one quiz. Premium costs £7.99 a month and adds all songs, playlists, offline sync, unlimited quizzes and Battle, and remote connections for up to 20 people. Singers can adjust key and tempo and select lead, backing, or guide vocals; guests can browse the catalog on a smartphone and add songs to the queue. KaraFun says it adds more than 400 new karaoke songs each month. Offline Sync can keep up to 1,000 songs on a device. Vocal Match compares a user's voice with songs and is available only on iOS and Android. Premium is for private use; professional or public performances require a professional subscription. Pro costs £39.99 a month and includes a commercial license and sound recording rights coverage with synchronized lyrics for its licensed catalog. Public performance royalties remain the customer's responsibility. One account can be used on only one device at a time, though the app may be installed on multiple devices.

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.
