osu! (lazer) is a free-to-win open-source rhythm game client developed in C#, supporting multiple game modes including osu!, taiko, catch, and mania. It is the next-generation cross-platform iteration of the popular osu! game, built on the ppy/osu-framework.
Use cases
- play rhythm games on desktop or mobile
- play osu! beatmaps on linux or mac
- play osu!taiko, osu!catch, or osu!mania modes
- download and play community-created beatmaps
- compete on global rhythm game leaderboards
- contribute to an open-source game client
When to choose
- you want a free, cross-platform rhythm game with active development
- you want to play osu! on linux, macOS, iOS, or Android where the legacy client is unavailable
- you want the latest osu! features and game modes before they reach the stable client
When to avoid
- you prefer the classic osu!stable experience with established tournament tooling
- you need a finished, feature-complete game rather than one under constant development
- you want a rhythm game unrelated to osu! gameplay styles
