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. Features - Name your own league and each tournament - Player registration with organizer-confirmed payments - Optional entry fee and your own payment link (Venmo, Zelle, Stripe, Google Form, etc.) - Automatic group stages and knockout brackets (quarterfinals, semifinals, final) - Live rankings and carry-forward player ratings - Personal match history and win/loss results - Multiple organizer roles
