Tournament Organiser is a free, easy-to-use web app that helps you run tournaments for any 1v1 or 2v2 competition—tennis, padel, FIFA, table tennis, and more. Simply enter player names, choose your game mode, and the app automatically creates balanced groups, generates fixtures, and tracks standings in real-time. Whether you're organising a casual weekend tournament with friends or a competitive league, the app handles all the logistics. It randomises team pairings for doubles, manages round-robin group stages, and creates knockout playoffs with visual brackets. Just input match scores as you go, and watch the leaderboards update automatically.
