Free and open-source table tennis tournament software.
From the community, for the community.
Run tournaments offline. No accounts. No subscriptions.
From players to the podium.
Everything you need to run a tournament, from setup to the final standing.
Build your player directory
Keep players and club information in one local directory, ready to use across competitions. Add them once and reuse them whenever you organize a new tournament.
Shape the competition
Create singles or doubles categories and define how each one will be played — from groups and qualifiers to match rules and the knockout stage.
Register players and get ready to play
Add players to categories, manage entries and check-ins, and keep track of everyone taking part before the first match begins.
Keep entry fees under control
Track entry fees, collect payments and handle refunds directly alongside tournament registrations.
Run every match with confidence
Follow matches through every stage, enter set-by-set results, and handle walkovers, retirements and corrections as you go.
From groups to the final
Advance qualifiers, create and adjust knockout draws, handle BYEs and lucky losers, and follow the bracket all the way to the champion.
Finish with a complete standing
Turn completed matches into clear final standings, from the tournament winner to every remaining position.
