I’m not familiar with Deepnote, but I have quite a lot of experience with Jupyter, and if someone were to ask me if there are more modern alternatives I would immediately point them to marimo (https://marimo.io/). For me marimo is already a successor to Jupyter, it has replaced it entirely for me.

But doesn't marimo force certain workflows that jupyter does not? For example its website states that "Notebooks are executed in a deterministic order, with no hidden state — delete a cell and marimo deletes its variables while updating affected cells." This appeals to people doing traditional software development work in notebooks, but it breaks workflows where people use notebooks as notebooks, where state is entirely separate from the in-notebook presentation of cells. Do people using notebooks these days hate this fundamental feature of notebooks? It's the key reason why notebooks aren't just a transcript of a REPL session!

Yup, Marimo seems perfectly gittable and Deepnote looks more of the status quo.

> Human-readable format: The .deepnote YAML format replaces .ipynb's messy JSON with clean, version-control and human-friendly structure for projects and notebooks. You can organize multiple notebooks, integrations, and settings into a single .deepnote project for better structure and collaboration.

I actually mostly use Jupyter for non-Python code (e.g. Julia or Ruby). How is Marimo's support for other languages?

Have to say marimo is excellent and is a breath of fresh air compared to Jupyter!

Marimo has been acquired (last week), does the SaaS enshitification pattern give you any pause?

Will github render a Marimo notebook as if it has already been executed, like they do for Jupyter notebooks?

x2 to marimo, please try it if you haven't.

I never really liked Jupyter. I've built a couple of "notebooks", as they have come to be known the days, much better than Jupyter and still switched to marimo, eventually. Quite similar to what I wanted to have.

One thing I like about marimo is the autocompletion's much faster than Jupyter.

How hard would it be to add creatine collaboration to Marimo?
