Horizon is a private osu! server, featuring multiplayer, PP, a very active community and a development team going strong implementing new features and squashing bugs. You can check out even more features here. It has also a very friendly community, and it's open source! Just so you know, we currently have users online!

What are you waiting for? Join Horizon! It's risk-free: you won't get your account banned on the official server if you play on Horizon.
You can also switch anytime between the official osu! server and Horizon!
