marimo

One hackathon team used marimo to turn an iPhone scan into a wheelchair-access check for small shops. Another used it to let scientists audit what their lab robots actually did. Both won. Full writeup below ⬇️

Shoutout to Pat Walters and OpenADMET for co-hosting with us, and thank you to all who participated!

How do you catch an AI agent that gets the right answer the wrong way? Acto built marimo apps that put experts in front of the evidence, bringing human review back into AI evals. Read the full case study below ⬇️

marimohub announcement closes our launch week. All announcements, in one place: marimo.io/blog/launch... Head over to our Reddit and Discord and let us know, what is the most useful for your workflow: pixi, fsspec, lens, studio or the hub?

marimo.ioIntroducing marimohubA self-hostable notebook platform to store, manage, and run marimo notebooks on your own infrastructure.

Use the infrastructure that fits your team. Docker on a VM or Kubernetes. S3-compatible storage or a filesystem. Your existing identity provider. Notebook files, versions, and metadata live in your storage backend. The notebooks stay ordinary Python files.

Organize notebooks into projects, share data connections, and choose who can edit, view, or use an app. Publish interactive apps for teammates, schedule notebook jobs, and review or restore earlier versions—all from the same hub.

Introducing marimo-studio 🎬 One notebook, infinite views. Turn an analysis into a report, explorer, or 3D experience, all using the web framework you choose. Every result stays backed by the reactive Python cells.

marimo.ioIntroducing marimo-studioBuild a view of your notebook for every audience, in any web framework, with every result traced back to the Python behind it.

See one quadratic programming notebook become a lecture, an explainer, and a hands-on lab. The athletes notebook becomes an overview, linked-chart explorer, and 3D field view. Read @peter_gyarmati's announcement: marimo.io/blog/introd...

Day 4 of our launch week. One more announcement lands tomorrow. Catch up on everything here: marimo.io/blog/launch...

Studio gives you two layers: pick the notebook outputs and values each audience sees, then design the view with HTML, React, Svelte, or any frontend stack. Each view lives beside the notebook, with results wired to marimo cells.

Ship for the audience you have: pre-render chosen interactive states as static files, with no Python runtime in production; run Python in the browser with Pyodide; or serve a live Python app with `marimo run`.

marimo.ioIntroducing marimo-lensExplore your notebook with your agent, see how its results fit together, and decide what to investigate next.

Introducing marimo-lens 🔍 Point at a chart, mark a region, and tell your agent what to investigate or change. Lens connects what you see to the code and data behind it. Your agent can point back, too. Read blog, by @peter_gyarmati: marimo.io/blog/introd...

Your agent can point back, too. Ask it to walk you through an analysis. Lens takes you from one output to the next, with a short explanation at each step. You move on when you’re ready. See how the results fit together and decide what to investigate next.

marimo.ioIntroducing marimo-lensExplore your notebook with your agent, see how its results fit together, and decide what to investigate next.

"Make this orange" "Why does this spike?" Just mark an output and leave a note. Your agent gets your selection, a screenshot, and the cell that produced it, plus its dependencies. Through marimo Pair, it can inspect the data, edit the code, and rerun the analysis.

marimo.ioRemote storage in molabConnect Google Drive, S3, Azure Blob Storage, and more to your marimo notebooks

You can now easily connect multiple remote storage types in marimo! If fsspec or obstore supports it, you can likely use it! Learn how in our blog, by @ShahmirVarqha: marimo.io/blog/drive-...

If you are training a model, @huggingface can become your go-to remote connection for model and data storage. And combining this with molab's RTX Pro 6000 GPUs it gives you everything you need to experiment with model training. See example here: molab.marimo.io/notebooks/n...

Remote file storage is the second of five new features we're announcing this week, as part of our launch week! Each day this week, we'll share something fun that the team has been cooking up. We are only starting up, so follow along on what's next here: marimo.io/blog/launch....

If you are teaching, @github filesystem support allows you to provide assets for your students and read them directly from the notebook. Which means you can finally retire these `git clone` instructions from the class materials and reduce that friction.

marimo now supports @prefix_dev Pixi sandboxes! Share portable notebooks with dependencies beyond Python, including CUDA-enabled @PyTorch, ffmpeg and R. Already using Conda or Pixi? Bring your ecosystem to marimo’s reactive notebooks, with Conda and PyPI requirements saved alongside your code.

marimo.ioIntroducing Pixi sandboxesPixi expands what you can build and share as a standalone marimo notebook, with dependencies from both Conda and PyPI.

We were thrilled to get early access to @typesafeai's Jev model! Here's what @ktaletsk is building with Jev: 1. jevframe - pandas and polars dataframe adapter to bulk generate new columns with Jev github.com/ktaletsk/je... Try the notebook: molab.marimo.io/github/ktal...

2. Adaptive UIs. Jev really shines in choosing UI elements depending on the context. Interactive marimo-pets widget knows which cell you're viewing and ranks the most useful tools for that code cell. Try here: github.com/ktaletsk/ma...

Congratulations to our @CoreWeave Hacks "Best Use of marimo" winners, Standard Physics! Their prototype uses iPhone scans to help shop owners spot potential accessibility issues. Built by Brendan Giang, Jerry Yan, Boris Nezlobin & David Wu.

In “One shop, one knob at a time,” sliders reshape a shop and rerun the app’s actual accessibility checks. That link between controls and computation made it stand out. Notebook source (local setup required): github.com/Imhaohao/st...
