Expose a Web App

If you build an interactive web app inside your notebook — such as a Streamlit data explorer, Plotly Dash app, or Gradio ML demo — you can expose it to a public URL using our flare tunnel tool.

1. In your Jupyter terminal, install flare:

   Copy Text

   pip install git+https://github.com/CERIT-SC/flare

2. Start your web application in the background (for example, a Streamlit app running on port 8501):

   Copy Text

   streamlit run app.py --server.port 8501 &

3. Expose the port using flare:

   Copy Text

   flare tunnel --port 8501 --name my-lab-dashboard

   Your interactive app is now live at https://my-lab-dashboard.flare.cloud.e-infra.cz!
