Karaoke Mugen

Karaoke Mugen is free, open-source software for organizing karaoke playlists at private parties and public events. It suits hosts who want guests to take part in choosing songs while keeping an operator in charge of the session. Its range of queue and playback controls is compelling, provided the host is willing to configure the setup and manage the event.

Overview

The app puts a host in control of the playlist but gives the audience ways to shape it: guests can suggest songs from their own devices, and the operator can enable voting on what plays next. That balance is useful when requests should be welcome without letting the queue run itself. Song and singing-time quotas, plus blacklists and whitelists, give the host further control, at the cost of some setup and rule-setting.

After installation, configuration, and updates, Karaoke Mugen can run without an internet connection. Guests must still be on the same Wi-Fi network, so this works for a prepared local event, not a remote crowd. Optional online features include update checks, karaoke repository downloads, online accounts, and shortened session URLs.

Key features

Playlist and event controls

Operators can add, remove, reorder, shuffle, import, and export songs; smart shuffle helps vary the queue without requiring the host to arrange every transition. Sessions, automixes, and quiz mode extend its use beyond a simple list of requests. These tools make it suited to an event with a host and a planned flow, rather than someone looking only for a personal singing app.

Playback, formats, and integrations

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 create tracks and display lyrics in dual-screen mode.

Users can connect AniList, Kitsu, or MyAnimeList accounts to get song lists from anime they have watched, and the current song can appear on a user's Discord profile. Online profiles can store favorites. A WebSockets API gives developers a way to build additional interfaces or clients, though that flexibility is most relevant to technically minded hosts.

Privacy and updates

Usage statistics are sent to Karaoke Mugen Server only with the user's consent. The Windows portable version does not support automatic updates; users must replace its files with a new ZIP archive to update it. That is a manageable trade-off for portable use, but less convenient than an installer-based update path.

Pricing

Karaoke Mugen is free, with no paid plan listed. Its MIT license also makes the software open source. There is no free trial because the free plan is the product's pricing model.

Platforms

Desktop builds are available for Windows, macOS, and Linux. Linux users need GLIBC 2.31 or higher, so older distributions may not run the supplied binaries. The web platform is also supported; guests can use their devices to suggest songs, but they need to share the host's Wi-Fi network.

Who it's for

Karaoke Mugen is a strong fit for a host running karaoke for friends or a public event who wants to combine audience requests with a controlled queue. It is less suitable for a remote group, since guest participation depends on the same Wi-Fi network, or for someone who wants karaoke without taking responsibility for managing playlists and session rules.

Pros and cons

Pros

• Guest requests and optional voting: the audience can contribute from their own devices while the operator retains control of song selection.
• Useful event controls: quotas, song filters, automixes, sessions, and quiz mode support more than an unstructured queue.
• Broad playback flexibility: mpv-supported video, ASS subtitles, multiple import formats, and pitch and speed controls accommodate varied karaoke libraries.
• Free and open source: the MIT-licensed app has no paid tier to weigh against its event-management features.

Cons

• Local-network constraint: guests must share the host's Wi-Fi, limiting participation to a local room or venue.
• Preparation is required for offline use: the app must be installed, configured, and up to date before it can run without internet.
• Linux compatibility has a floor: GLIBC 2.31 or higher is required for the supplied binaries.
• Portable Windows updates are manual: updating means replacing files from a new ZIP archive.

Alternatives

Karaoke Software is the broader category to explore when comparing options. Karaoke 5 is worth considering for Windows, macOS, Android, or iOS users who want a player and manager on a free plan, but that plan gives up synchronization, YouTube downloads, mobile management, and music quiz features.

OpenKJ is another free, open-source hosting option, with a separate Songbook plan at $9.99 a month for readers considering a paid songbook. KaraFun may suit people who want a freemium app with free songs and Premium previews; its Premium plan costs £7.99 a month.

Nightingale is another free, open-source karaoke app. Smule is a better alternative for someone who wants to join existing duets at no cost, with a VIP All Access Pass at $19.99 a month.

TKaraoke is a freemium alternative for Android, iOS, or Windows users. Kanto Karaoke Player&Recorder has a free Windows version capped at five playlist songs, one-minute recordings, and one-minute MIDI-to-MP3 conversions, with no professional use. Performous is another free option for Linux, macOS, and Windows.

Verdict

Choose Karaoke Mugen if you want a free, flexible way to run a host-led karaoke event where guests can request songs and vote. Its event controls and wide playback support make it more than a basic player, but the shared-network requirement and preparation burden make it a poor fit for remote participation or hands-off karaoke.
