## What it is
Bracket is a free, open-source, self-hosted tournament management system with a FastAPI backend and a React/Vite frontend built on Mantine. It supports single elimination, round-robin, and Swiss formats with multi-stage tournament structures, drag-and-drop match scheduling, team/player management, and public dashboards.

## Use cases
- run a self-hosted tournament for a local sports club
- manage single elimination brackets for a competition
- organize round-robin leagues with teams and players
- run Swiss-system tournaments with automatic match scheduling
- publish live schedules and rankings to a public dashboard
- schedule matches across multiple courts with drag and drop
- manage multiple clubs and tournaments from one system
- replace expensive closed-source tournament software

## When to choose
- you need an open-source, self-hosted alternative to paid tournament platforms
- you need Swiss, round-robin, and elimination formats in one tool
- you want multi-stage tournaments with groups and brackets
- you want a public dashboard showing schedules and rankings
- you want a REST API to script tournament state changes

## When to avoid
- you need deep integrations with existing sports federation systems
- you want a hosted SaaS with no server maintenance
- you need mobile-native apps rather than a web interface
- you need formats beyond elimination, round-robin, and Swiss
