Introducing marimohub 🌊 Your team's notebooks. Your infrastructure. An open-source platform to run and share marimo notebooks with your own compute, storage, and SSO. No separate database to operate. Read @themylesfiles' announcement and get started: marimo.io/blog/introd...

Introducing marimohub

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

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.

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...

Introducing marimo-lens

Explore your notebook with your agent, see how its results fit together, and decide what to investigate next.

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-...

Remote storage in molab

Connect Google Drive, S3, Azure Blob Storage, and more to your marimo notebooks

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.

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...

A feature a day keeps the builders at play, or however the saying goes. Launch week #2 starts Sept 28. 5 days, 5 announcements, 5 videos. What do you think (or hope) we'll launch? Best guess might just get merch...

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.

For our cheminformatics competition, you can now win an @Apple Mac Mini M6. You have 1 month left to take a dataset and build a marimo notebook that brings cheminformatics to life. Competition details below.

33 days to win a mac mini. the challenge: pick a cheminformatics dataset and build a marimo notebook that answers a question you want the answer to. we're judging based on creativity, not on model accuracy. co-hosted with @wpwalters.bsky.social. we'll see you in our submissions 👀

Our community call is in 20 minutes. Another teaser for what's in store:

What if you could run marimo notebooks for your whole company on your own cloud, behind your own SSO, with no database to run? We'll be demoing exactly that at tomorrow's community call 👀 Plus...custom web views. That's all we're saying for now.

We're running a cheminformatics notebook competition with @wpwalters.bsky.social and OpenADMET. Take a dataset & bring cheminformatics to life. Mac Mini + $2.5K in prizes, deadline Oct 4 👀

PSA 0.24.0 is out. here's what's new: @hf.co Hub is now a first-class remote storage backend. marimo detects the Hugging Face auth in your environment and lists your datasets, models, and Spaces in the sidebar.

hint: __hub that's all you get until august 25, when we'll show you our new features and then hand the mic to @sconradi.bsky.social, @mihainica.bsky.social, Sasank Desaraju, and @clarencemah.me.

marimo 0.23.16: your notebook now finds your database connections for you. Postgres, MySQL, Trino, AWS, PyIceberg, PySpark, if it's configured on your machine, it shows up in a quick-add UI.

We're hosting another community call to kick off the quarter, with team demos, some highly-requested features, and presentations from the community. 🗓️ Aug 25, 2026 | 12-1 PM PST Whether you're a marimo megafan or marimo-curious, this one's for you: luma.com/13c69h7x

We had our first ever launch week here at marimo. Five announcements in five days. Full recap ⬇️ marimo.io/blog/launch...

marimo is doing a launch week

One week. Five announcements. Can you guess what's coming?

Python is better than PowerPoint now. You can present marimo notebooks as slides. Widgets stay interactive and you can edit slides live while presenting. No more second window, separate demo, or crossing your fingers.

marimo is reactive, which means that it knows in what order variables are declared. So what if you had widgets at your disposal that could leverage that? For launch week, we're releasing some tools that do exactly this.

Ask and you shall receive: marimo now runs natively in PyCharm. Open, edit, and run reactive notebooks in @JetBrains without leaving your IDE. Install from the JetBrains Marketplace 👇

Open any marimo notebook on GitHub. Click one button. The raw Python turns into a live, interactive notebook you can run, right there in your browser. That's marimo Glance. Free extension for Chrome and Firefox, works on GitHub, gists, and GitLab. Details below.

Put a slider in one paragraph and the chart three paragraphs later. The Python cells stay connected. Reactive marimo cells now run inside Quarto, Jupyter Book, and anywhere MDX lives. quarto-marimo, jupyter-book-marimo, mdx-marimo, all open source. More below ⬇️

happy official launch day 1! launch week opens with updates to marimo-pair, now in VS Code. pair opens up a new medium for agent-native data and computational work: you + your agent, collaborating over one interactive, flexible canvas. more below ⬇️ marimo.io/pair

marimo pair — a thinking canvas for you and your agent

Give your agent a marimo notebook. The ease of chat, the rigor of software.

SciPy was a blast! Missed Trevor Manz's anywidget talk or Dylan Madisetti's caching poster? Not to fear, for our first ever launch week is here...5 new announcements next week. What are you hoping it'll be?

I finally tried out the @marimo.io marimo-pair skill to do some light data analysis and plotting in conversation with an LLM and it really worked. Tedious plotting layout and syntax fadeed into the background. I used OpenCode + GLM 5.2, @pola.rs and @matplotlib.org Would recommend. #EnergySky

molab has free GPUs and we've been exploring the different ways that you could use them. And there's plenty to do outside of deep learning! You can use them to tackle TSP problems too. But it helps to rethink your CPU-based algorithms when you go here. youtu.be/1-5wkzdP1Jc
