Tournament system meant to be easy to use. Bracket is written in async Python (with FastAPI) and Vite as frontend using the Mantine library.

It has the following features:

  • Supports single elimination, round-robin and swiss formats.
  • Build your tournament structure with multiple stages that can have multiple groups/brackets in them.
  • Drag-and-drop matches to different courts or reschedule them to another start time.
  • Various dashboard pages are available that can be presented to the public, customized with a logo.
  • Create/update teams, and add players to teams.
  • Create multiple clubs, with multiple tournaments per club.
  • Swiss tournaments can be handled dynamically, with automatic scheduling of matches.

Live Demo

A demo is available for free at https://www.bracketapp.nl/demo. The demo lasts for 30 minutes, after which your data will de deleted.

Quickstart

To quickly run bracket to see how it works, clone it and run docker compose up:

git clone git@github.com:evroon/bracket.git
cd bracket
sudo docker compose up -d

This will start the backend and frontend of Bracket, as well as a postgres instance. You should now be able to view bracket at http://localhost:3000. You can log in with the following credentials:

  • Username: test@example.org
  • Password: aeGhoe1ahng2Aezai0Dei6Aih6dieHoo.

To insert dummy rows into the database, run:

docker exec bracket-backend uv run --no-dev ./cli.py create-dev-db

See also the quickstart docs.

Usage

Read the usage guide for how to organize a tournament in Bracket from start to finish.

Configuration

Read the configuration docs for how to configure Bracket.

Bracket's backend is configured using .env files (prod.env for production, dev.env for development etc.). But you can also configure Bracket using environment variables directly, for example by specifying them in the docker-compose.yml.

The frontend doesn't can be configured by environment variables as well, as well as .env files using Vite's way of loading environment variables.

Running Bracket in production

Read the deployment docs for how to deploy Bracket and run it in production.

Bracket can be run in Docker or by itself (using uv and pnpm).

Development setup

Read the development docs for how to run Bracket for development.

Prerequisites are pnpm, postgresql and uv to run the frontend, database and backend.

Translations

Based on your browser settings, your language should be automatically detected and loaded. For now, there's no manual way of choosing a different language.

Supported Languages

To add/refine translations, Crowdin is used. See the docs for more information.
