While preparing a screencast with Manuel, we searched for real-time collaboration tools for Jupyter notebooks. JetBrains' "Code With Me" proved unsuitable, displaying only raw JSON. Here are two practical alternatives:

1. Visual Studio Code's "Live Share" extension
2. Launching JupyterLab server like this: jupyter-lab --collaborative

If you're aware of other collaboration tools for Jupyter notebooks suited for screencasts, please drop me a note 😄!
