JupyterHub or marimo?

JupyterHub if you want the published Colab-shaped multi-user server (the path). marimo if you want that reactive Python file — /compare/jupyterhub-vs-marimo.

No. Cited research stays on /replace/notebooklm (SurfSense). This page is a data-science kernel.

JupyterHub and JupyterLab are BSD-3-Clause. marimo is Apache-2.0. You pay hosting and any GPUs you attach. Template users never pay c17.

JupyterHub / marimo

Notebooks you host. JupyterHub is BSD-3-Clause; marimo is Apache-2.0 — Google Colab without the hosted runtime seat.

The problem

Google Colab is a hosted notebook runtime. You wanted kernels, users, and a notebook file on hardware you control. JupyterHub is BSD-3-Clause (jupyterhub/jupyterhub; last push 24 Oct 2026) — a multi-user server that spawns Jupyter notebook servers. marimo is Apache-2.0 (marimo-team/marimo; last push 25 Oct 2026) — a reactive Python notebook stored as a script. JupyterLab is BSD-3-Clause if the job is the IDE JupyterHub can spawn. This is not Colab's every GPU SKU, Drive mount, or hosted runtime. A research Q&A notebook stays on /replace/notebooklm (SurfSense).

Agent setup prompt

Replace Google Colab with JupyterHub (preferred) or marimo (https://jupyterhub.readthedocs.io / https://marimo.io).

- Official docs. Persist notebooks on a volume. Create one user and one notebook. Do not claim Colab GPUs, Drive mounts, or hosted runtimes.
- marimo if the job is a reactive Python file. JupyterLab is the IDE JupyterHub can spawn. Research Q&A stays on /stacks/surfsense-research.
- Write AGENT_PROMPT.md.
