Reactive cells solve Jupyter's hidden state problem
From 3 comments
Very cool! This is something Jack Rusher cries for in his talk "Stop Writing Dead Programs" https://www.youtube.com/watch?v=8Ab3ArE8W3s
zengid on HNThis is a great idea. I'd been planning to create something similar where cells are topologically ordered based on their dependency structure; although I was thinking perhaps to…
bsdz on HNThis is good, I've been waiting for something like this to solve the issue of determinism in notebooks.

Plain Python file format is git-friendly
From 2 comments
This is amazing. I'm a big user of both Jupyter notebooks and Observable notebooks (https://observablehq.com/) and the thing I miss most from Observable when I'm using Jupyter is…
simonw on HNThis is very cool. I think I need to play around with this a bit more to wrap my head around the reactivity element, but the basic shift of ipynb to standard Python would be such…

Welcome alternative to Jupyter
From 2 comments
This is a welcome alternative to Jupyter Notebooks/lab- great work! One thing that would be nice is an ability to see previews on GitHub of the Marimo notebook (like Jupyter…
j0e1 on HNVery interesting project, a breeze of fresh air and welcome competition to Jupyter. I guess it's still very early but the onboarding for Mario VSCode is not great at the moment,…

Package reproducibility not yet solved
From 2 comments
That's one interesting project. As someone who relies heavily on collaboration with people using Jupyter Notebook. The most annoying points about reproducing their work are the…
bluish29 on HNYes, the second half of reproducibility is for sure packages. A solution for reproducible environments is on our roadmap…

Reactivity misses in-place object mutations
From 1 comment
Looks really impressive! But state is not tracked perfectly. Sometimes you have to manually re-run the cell. For example if one cell defines a dataclass d and another cell…

Lacks interactive debugger and variable viewer
From 1 comment
I love this, but Im using DataSpell from JetBrains at the moment because it has 2 killer features: ``` 1. Variable viewer so I can see the current value of all variables in…

WASM/Pyodide browser version
From 3 comments
Looks cool! Have you looked into WASM? Something like a jupyterlite [0] alternative for marimo? And are there plans to integrate linting and formatting with ruff? [1] [0]…
SushiHippie on HNCool. On a side note, I think the old Jupytext extension is hugely underrated. It lets Jupyter run a .py file (with markdown notes as comment in the file, displayed as notes in…
wisty on HNIt would be amazing if it could be deployed with pyodide/wasm as an alternative to a Python web server. Truly a standalone interactive notebook, hosted with plain html.

Editing the file externally with live update
From 1 comment
That's amazing! Can I edit it in another editor, save the file and have it updated live in the browser notebook? Or does it have to recompute everything?

Relationship with Jupyter ecosystem and widgets
From 1 comment
Very exciting! I took a quick look and I have a couple of questions. 1. Can you describe your interactive widget story? I see that you integrated altair, and there is some custom…

Converting existing Jupyter notebooks with custom JS and CSS
From 1 comment
The readme says that I can convert Jupyter notebooks, but to what extent does this actually work? What if I've imported custom JS to render mathjax or added custom CSS? What if…

bluish29 on HNI already use jupytext to store notebooks as code but the improved state management and notebook-as-app features are pretty compelling and I'm trying it out. Unfortunately, I'm…

Streamlit

Looks cool. This is kind of like streamlit, which (I think) tried to escape the limitations of notebooks by giving you an API to quickly make a shareable app with sliders/charts…
