DuelSync
Built for tournament organizers.
A companion for KTS
DuelSync is an unofficial desktop app for Yu-Gi-Oh! tournament organizers running Konami Tournament Software. Organizers keep using KTS as the official source of truth. DuelSync reads the live tournament file and turns it into a calmer local dashboard and a hosted page players can actually follow.
Automatic KTS sync
A background watcher reads the KTS .Tournament file as soon as it changes, no manual exports, no copy-paste.
Cleaner organizer dashboard
A focused local view of pairings, standings, and match results, designed for the tournament floor.
Public read-only player pages
Publish a hosted page so players can follow pairings and standings live, with a QR code to share at the venue.
Top Cut bracket support
Run single-elimination Top Cut beyond what KTS handles natively, kept in sync with the rest of the event.

Community Players

- Makes it easier to grow and understand your community.
