LeagueMakerApp is a free, browser-based tournament and league management platform for any sport or game. Organizers can run round robin leagues, knockout brackets (single and double elimination), Swiss tournaments, McMahon pairings for Go, and Americano padel events — or build a fully custom format from scratch.
The platform generates pairings automatically round by round, tracks live standings with configurable tiebreakers (Buchholz, Sonneborn-Berger, and others), and handles seeding, byes, and manual pairing adjustments for late arrivals. Results and standings pages update live and can be shared with players via a public link — no account needed to view them.
Everything runs in the browser with no installation, works on mobile and desktop, and is available in 16 languages. LeagueMaker also supports niche formats like EGD wallist export for Go and TRF export for FIDE-rated chess events.
