Did I read it correctly that, unlike Jupyter Notebook, none of them are FOSS alternatives or competitors, much less self-hosted FOSS?
- Google Colab is fully closed source and I think there is no self hosted option.
- Deepnote is fully closed source and I think has no self hosted option.
- Saturn Cloud enterprise is a self hosted option for Saturn Cloud. Saturn Cloud is I think a nice management layer around open source JupyterLab.
- I think Apache Zeppelin is self-hostable FOSS.
