UltraStar Deluxe

UltraStar Deluxe is a free, open‑source karaoke application that runs on Windows, Linux and macOS. It reproduces the gameplay of commercial karaoke titles, allowing players to select a song, view onscreen lyrics and pitch indicators, and sing along using a microphone. The software supports the creation and import of custom song files, so users can add their own music and lyrics to the library.

The program is aimed at home users and hobbyists who want a PC‑based karaoke experience without purchasing a console game. It appeals to people who enjoy singing with friends, organizing karaoke sessions, or building a personal collection of tracks. Because it is open source, the community can contribute updates, bug fixes and new features.

UltraStar Deluxe is released under a stable maturity level and receives regular updates, as shown by its frequent version releases. Its cross‑platform support and the ability to author custom songs distinguish it from proprietary karaoke solutions.
