OpenKJ vs Singa

OpenKJ is open-source karaoke hosting software for karaoke DJs, built and tested for Linux, macOS, and Windows. It integrates with OpenKJ Songbook, which supports web-based song search and submissions. Singers can use Songbook apps for iOS and Android to browse or search a songbook, submit songs with requested key changes, and save favorites. The web submission site can also serve as a venue kiosk, and sign-up requests are sent directly to the host computer. Songbook can optionally display download-vendor catalogs; the project says these are updated daily. OpenKJ SongShop supports purchasing and downloading karaoke files on the fly, with PartyTyme listed as the only available vendor. OpenKJ Tools provides utilities for ReplayGain adjustment, archive handling, zip compatibility, and filename capitalization. Those tools are marked experimental, and the project recommends backing up the library before using them. OpenKJ is free; Songbook starts at $9.99 per month and has a one-month free trial.

Singa is a karaoke streaming service for singing at home or at venues powered by Singa. Its licensed catalog has over 120,000 songs, including original artist recordings and tracks in English, Spanish and more than 40 other languages. Singers can change pitch, turn on guide vocals, manage a queue and use a pop-out player. AirPlay can send karaoke to a compatible television while users browse songs and control the queue on an iPhone or iPad. Consumer Freemium and Premium plans are for private use; commercial use requires a Business license. Singa Business serves venues, schools, care homes and nonprofits, and its Business Box offers session and time management, kiosk mode and prepared playlists for karaoke rooms. Premium costs $9.99 a month or $89.99 a year; both renew automatically unless canceled, and prices may vary by country. Singa Pro costs €99 a month and includes professional use. Songs stream online and cannot be downloaded as audio or video files, and the service has no performance-recording feature. Singa is available on Android, iOS and web.
