A JavaScript library for managing tournament brackets (round-robin, single/double elimination) with full logic and storage abstraction.
brackets-manager.js is a JavaScript library that provides the complete logic for managing tournament brackets, including round-robin, single elimination, and double elimination formats. It solves the problem of handling complex tournament structures, match states, seeding, and multi-stage flows programmatically, without being tied to a specific storage or visualization layer.
Developers building esports platforms, gaming tournament systems, competitive event applications, or any software requiring programmatic bracket management.
Developers choose brackets-manager.js for its storage-agnostic design, comprehensive API covering all bracket operations, and its inspiration from established platforms like Toornament and Challonge, ensuring robust and battle-tested logic.

The library uses an abstract storage interface, allowing seamless integration with any backend like JSON, SQL, or Redis, as highlighted in the README's example with JsonDatabase.
It provides modules for all bracket operations—create, get, update, reset, delete, and find—offering a full-featured management system for tournament data.
Supports complex flows like round-robin stages feeding into elimination brackets, enabling sophisticated event structures as described in the features.
Includes specific handling for BYE seeding, forfeits, and multiple match states (e.g., locked, completed), essential for realistic tournament management.
The library only provides logic; displaying brackets requires integrating a separate library like brackets-viewer.js, adding setup complexity and dependencies.
While storage-agnostic, you must implement or use external storage modules, which can involve additional configuration and learning curve beyond core logic.
It lacks features like user authentication, payment processing, or real-time updates, forcing developers to build or integrate these separately for a complete platform.
brackets-manager.js is an open-source alternative to the following products:
Toornament is an esports tournament management platform that provides tools for organizing, managing, and streaming competitive gaming events.
Challonge is a tournament bracket management platform that allows users to create, organize, and share tournaments for esports, gaming, and other competitive events with real-time updates.
