About DiamondOS
The complete operating system for baseball leagues and teams. Built by coaches, for coaches — and everyone else who makes the game happen.
Our Mission
Running a baseball league shouldn't require a spreadsheet empire. DiamondOS gives commissioners, coaches, parents, and players one platform to manage everything — from drafts and schedules to live scorekeeping and real-time stats.
Whether you're running a youth rec league, a men's baseball league, or managing a single team, DiamondOS handles the operations so you can focus on the game.
