Lidarts is a free/libre, open-source online darts scoring website.

The project is mostly written in Python3. The backend is based on Flask-Socketio. gevent workers are managed by gunicorn and communicate over redis. Data is stored in a PostgresSQL database. HTTP requests and WebSockets are proxied by nginx.

The entire project is driven by volunteers. Everyone is invited to contribute. Join us on our Discord server!


To set up a development environment make sure you have Python 3.6 or later installed.

Install the system requirements. Change "python3" to a different version (e.g. to "python3.7-venv" etc.) if you have a custom installation of Python and you don't want to use the system default.

sudo apt-get update
sudo apt-get install python3-venv python3-dev build-essential redis-server

Clone the repo

git clone lidarts-dev

Create a new virtual environment and activate it

cd lidarts-dev
python3.7 -m venv venv
source venv/bin/activate

Install dependencies

pip install -r requirements_dev.txt

Create instance folder and copy example config

mkdir instance
cp example/ instance/

Create the database

python createdb

There is currently an issue with the migrations directory. Remove it and initialize it again

flask db init
flask db migrate
flask db upgrade

Run the development server with

python runserver
