I coach Tennis and for years I was stuck using whiteboards, PowerPoint, or overpriced software that only worked for one sport.

I wanted something simple draw a play, share it with my team in seconds, on any device. Nothing existed that did all of that.

So I built CourtDraw. It started as a weekend project for my own sessions. Now it supports 38+ sports, runs entirely in the browser (no install, no account required), and is used by coaches from padel to basketball to hockey.
