Run Locally

Run locally by cloning the repository and installing the dependencies. We recommend using a virtual environment to isolate the dependencies from your system.

Before you start, make sure you have the following installed:

• Poetry
• Node.js

For the backend, you will need to install the dependencies and start the development server.

poetry install
make run_backend

For the frontend, you will need to install the dependencies and start the development server.

cd src/frontend
npm install
npm start

---

Docker compose

This will run the backend and frontend in separate containers. The frontend will be available at localhost:3000 and the backend at localhost:7860.

docker compose up --build
# or
make dev build=1
