UltraStar Deluxe is a free and open source karaoke singing game for PC, inspired by Sony's SingStar, where up to six (or twelve in party mode) players sing along with music using microphones and are scored on pitch and rhythm. It supports custom user-created songs, themes, Lua plugins, and runs on Windows, Linux, and macOS.

Use cases

• host a karaoke party at home with multiple players and microphones
• play a free SingStar-style singing game on PC
• sing my own song collection instead of buying song DVDs
• score players on singing pitch and rhythm
• create and add custom karaoke songs
• customize the game with themes and Lua plugins
• run a karaoke game on Linux or macOS

When to choose

• you want a free, open-source SingStar alternative on desktop
• you want to use your own DRM-free audio files and community songs (10,000+ available)
• you need multi-player party mode with microphone pitch scoring
• you want a game that works across Windows, Linux, and macOS, including SingStar microphones

When to avoid

• you need a mobile or console karaoke app
• you want an online streaming karaoke service with licensed catalogs
• you are unwilling to configure song directories and settings via config.ini
• you need professional vocal-training software rather than a party game
