I don't know much about this, but I understand Project Jupyter is Nonprofit. If I go to "jupyter.org" I see a tab "Community" and another "Governance". If I go to "deepnote.com" I see "Customers" and "Pricing".

Why would people want a standard to be controlled by a private company? I don't think the "Open-Sourcing" of it says enough. How does licensing work with formats or standards?

A lot of the comments on here are too pessimistic. Deepnote has had the single best jupyter interface for years now - unfortunately locked behind a cloud subscription though. Jupyter itself has been stagnant for far too long, and it's much appreciated there's more options coming online that have a modern level of polish.

Marimo is great, but it's good to have competition in the space (especially when both projects are still owned and maintained by VC backed companies).

Lot's of notebooks floating around.

I love notebooks, I use them all the time for teaching, writing (all of my books are written in notebooks), EDA, model development, and more. I've spoken at Jupytercon.

Having said that, I've never played around with other notebook implementations (ok, I've used IPython Notebook, Jupyter Notebook and Lab, Google Colab, ein (emacs), Jupyter in Vscode, and Notebook (.py) files in Vscode).

I've seen Joel's rant about notebooks, and they do have drawbacks.

But I would rather push better programming practices (chaining pandas, using functions, rearranging cells) than have dependent cells written in the horrible piecemeal style that I see all around the industry.

My biggest issue with notebooks is JSON. I've used Jupyter to get around it for years, and now many LLMs are decent at writing Jupyter JSON.

I'm not involved in any capacity with the development or use of Jupyter—I think ipynb is fundamentally flawed at a deep level, starting with its (I)Python roots—but this company's framing of their product as "the successor to Jupyter notebook" comes across as passive aggressive at best and misleading at worst. What is their relationship to Jupyter besides building a Jupyter alternative?

Haha I've asked LLMs to avoid fluff in a prompt and gotten exactly a heading like that one wkth "(no fluff)" before.

Otherwise I've followed DeepNote since they started. I agree with other comments that it's icky to announce yourself as a successor to someone else's project, but always nice to have more options for open source

Way to undermine an interesting product launch through poorly chosen language:

> Let’s be frank the single‑player notebook has felt outdated for a while now. We’re open‑sourcing its successor. Jupyter belongs in the hall of great ideas — alongside “Hello, world.” and “View Source.”

If you're trying to reach out to the Python community this is not the way to do it. Completely unnecessary hostile language there! Have some respect.

My advice to Deepnote is to scrap this launch announcement (ideally with an apology) and try again. They've built something genuinely useful and interesting but it's going go get a lot less attention than it deserves if they introduce the open source version to the world like this.

Wouldn't the successor for Jupyter be decided by adoption? For a single team to self declare this seems a bit crass, no?

> Teams need notebooks that are reactive, collaborative, and AI‑ready

reactive: this matters, but all the alternatives have it

collaborative: this matters very little in the Figma / Google Docs sense of collaborative in practice. It's very rare you want two people working on the same notebook at the same time. What you really want is git style version control.

AI‑ready: you want something as close to plain python (which is already as AI-ready as it gets) as possible.

if you're measuring across these dimensions, I'd go with marimo.

marimo is saved as plain .py files, easy to version control and has a reactive model.

Title and first paragraph make it sound like this is a project by the same people as (or endorsed by them) Jupyter. Apparently that's not the case and also it looks very similar to google colab so jupyter + better UI + some LLM integrations

But kudos for going oss

The hubris of this self declared successor. It’s not even the same team.

> Across the Fortune 1000, job postings that mention and require Jupyter knowledge are down sharply

The obvious question is whether Jupyter is being replaced in those postings, whether those types of jobs are proportionally rarer, or whether the whole market is simply hiring less.

Jupyter is still best in class and I can think of a few other explanations for this stat.

This sucks from both a press release standpoint and how it's not actually a successor (didn't see any quotes from folks in Jupyter blessing this).

I hope the "founders" go back to the drawing board and retry

Hasn't LiveBook had multiplayer editing for a few years now?

This is an ad.

Are there any other people who hate notebooks? Give a plain old script anytime. Run and edit anywhere without extra packages or even a Web browser.

Most heavy users of python notebooks (including us) have a hate love relationship with it, especially when you add it into git.

Honestly this is worth alone for the fact that there isn't random JSON blobs coming in PR diffs.

I wish more people tried it out instead of complaining about the blog post text.

Can someone clarify how deepnote has the authority to declare the "successor" of Jupyter?

The framing of this title makes it seem like Jupyter is dead. It, in fact, is not.

I'm confused. I checked out the repo and I don't think the notebook itself - the equivalent of Jupyter is open source yet:

https://github.com/deepnote/deepnote/

What's the equivalent of `jupyerlab run`?

> You'll soon be able to:

> Take the UI you're used to from Deepnote Cloud and run it locally > Edit notebooks with a local AI agent > Bring your own keys for AI services > Run your own compute

Do people find this sort of writing appealing?

For me, it's cringe to borderline painful to read.

Jupyter does not have (or need) a successor.

Very few objections to Jupyter that are not addressed by `nbconvert`.

It's telling that Wolfram / Mathemetica doesn't even come up in a blog post like this, as the inventors of "the notebook". Jupyter took the concept to a whole new level, but the concept did originate in Mathematica 30 years ago!

Claiming that the number of job postings mentioning Jupyter has decreased, so Jupyter is no longer popular is not something a company in the data space should do. It is just embarrassing.

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.

You claim it’s a successor, but is everyone really on board with that? I love jupyter, but generally feel like having to run a server is the downside.

The nice thing about jupyter notebooks is that you can run them inside vscode without an explicit server, but I like to just use %% so that I can run it in zed and vs code and it’s just a python file that doesn’t need conversion.

Oh, and it's Apache 2 licensed, so actually open source and not just pretending for the cred.

Sincerely, nice.

What’s these folks relationship to Jupyter? I guess they must be some of the really prominent Jupyter developers? Otherwise declaring their system the successor to such a widely used tool seems pretty presumptuous.

Might wanna spell-check the post if you want any credibility on your claim:

> worfklows

Observable is already open-sourced and well-respected. Bold and ridiculous to claim your random product is "the successor" of a well-known project, without any obvious relationship to the founders/maintainers of the thing you claim to be aping.

Framing of this seems a bit nasty tbh - jupyter deserves a little bit of respect on its name!

>Meanwhile, the market is voting with its feet. Across the Fortune 1000, job postings that mention and require Jupyter knowledge are down sharply; the most recent month was deep in the red YTD.

This is a joke, right?

If the job postings for Jupyter go down, what exactly will happen to an "AI"-first replacement when "AI" weariness is rising sharply?

"AI" has achieved what seemed impossible in 2019: It makes people hate all tech and gets them away from computers.

I'm Jakub, CEO of Deepnote.

Didn't expect to see this trending here! We worked hard to execute on our vision of a data notebook and I'm glad we finally got a chance to open source it. We stand on the shoulders of giants. AMA!

Instead of contributing to Jupyter, we will create another tools

I'm pretty confused why a company would waste such an important announcement / milestone with a clearly llm-generated blog post.

The successor to Jupyter notebook is Marimo, https://marimo.io/ because they are pure code, not code in json. First class everywhere.

I love how opensourcing it basically in today's world is a precursor to we're sunsetting it.

as me and my co-worker used to joke, "marimo is the mclaren of notebooks".

standing up Bingo!

(Anybody still familiar with "bullshit bingo"?)

The article reads as if generated by AI. Lol

How is this a “successor”? It’s not tied to the Jupyter project in any way? Looks like a scummy ad for some subpar aislop product?

Jupyter use is declining because coding agents got really good. Multiplayer mode is not going to save it.
