OpenKJ vs StarMaker

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.

StarMaker is a karaoke and social singing app for singing, recording, and sharing performances. Its catalog includes more than 14 million songs, with tracks in different styles and keys. Scrolling lyrics and instant pitch feedback are available while recording, and more than 30 AI-enhanced audio effects can be used on singing videos. Practice options include vocal-range tests, warmups, and daily breath-control and rhythm exercises. Radar Chart Analysis gives feedback on pitch precision, rhythm, technique, emotion, and song choice. Users can sing solo or in duets, join live broadcasts and Party Rooms, and participate in interest-based Family communities. The app supports sharing recordings to social platforms including WhatsApp, Facebook, Instagram, Twitter, and Snapchat. The website has a songbook with playlists, genres, artists, and recommendations, and offers entry to global online SupernovaX auditions, held in two seasons each year. StarMaker is available on Android, iOS, and the web. It is free with ads and in-app purchases. Pro subscriptions are listed as $7.99 per week, $14.99 per month, or $59.99 per year.
