Powdy

Powdy lets you create and run your own table tennis league or tournament — for a friend group, office, dorm, or club. You set it up; you run it.

Name your league, register players, generate group stages and knockout brackets, enter match scores, and track live rankings, ratings, and everyone's personal results.

Powdy is a personal, general-purpose tool. It is not affiliated with, endorsed by, or representing any school, club, business, or organization — every user sets up and manages their own league independently.
