Hi! molab is not available for self-hosting. For self-hosting, you have a few options:

Use marimo open source. This can be self-hosted in the same way that Jupyter can. Repo: https://github.com/marimo-team/marimo

Use marimo's WebAssembly notebooks (exporting to WASM-powered HTML). For example, that's how Cloudflare is sharing marimo notebooks currently: https://notebooks.cloudflare.com/. Docs: https://docs.marimo.io/guides/exporting/#export-to-wasm-powe...

Use within JupyterHub: https://github.com/jyio/jupyter-marimo-proxy
