Collaborative Tools and Workflow

For Notebooks (R, python, julia, js, …) with real time collaboration CoCalc seems to be the best option right now. It worked great last time so we’ll stick to it for now. You need to register an account there (it is free).

Other real time collaboration tools

Feel free to add suggestions to this list

• VS Code with Live Share Extension (very promising but notebook support not yet stable), languages: python, R, julia, …
• Jupyter Lab real time collaboration (alpha feature), languages: python, R, julia, …
• Observable multiplayer (experimental feature), languages: javascript
• Jupyter Lite: in browser version of Jupyter Lab, languages: javascript, (a subset of) python
