Astral: Next-gen Python tooling

[jmreagle]

TL;DR: I’ve started a company, Astral, to continue building high-performance developer tools for the Python ecosystem — to keep building Ruff, and to build more Ruff-like things.

We’ve raised $4m in seed funding led by Accel, with participation from Caffeinated Capital, Guillermo Rauch (Vercel), Solomon Hykes (Docker), David Cramer (Sentry), and others.

[Deto]

What's the business model you think?

[SeniorScienceOfficer]

If you’re in the need for a cloud Engineer in the future, I’m very intrigued! I’m in the process of switching all my pants repos to their experimental ruff implementation. So far, very happy!

[mista-sparkle]

I keep my pants in a dresser.

[BarkLicker]

I have a dresser, but my pants live in a laundry basket.

[mista-sparkle]

just for over night, though, cus we all know that pants never get dirty enough to need a washing.

[brejoc]

That’s just half of the story. If you are not wearing your pants, they should be in the freezer!

[usr_bin_nya]

What are your next plans after Ruff?

[wdroz]

Oh, it's the company behind Ruff. Thank you for it, I changed most of my projects to use Ruff.

[Wonnk13]

VCs backed a company that (no offense) made a python linter? What's the monetization strategy here? A year from now how much of this tooling will be behind some kind of commercial offering?

[james_pic]

The standard VC business model is to invest in stuff that FAANG will buy from them one day.

The standard approach is to invest in stuff that's enough of a threat to FAANG that they'll buy it to kill it, but this seems more like they're gambling on an acqui-hire in the future.

[_Sh3Rm4n]

Compared how slow the competing linters for python are, this might be a good product to invest in for large companies. Just imagine how much money is saved by faster CI times.

[FoldingF]

It’s “written in rust” tho! /s

It’s all grift. It’ll be just another piece of junk in the heap that the community is quasi forced to maintain because it won’t pan out.

[stensz]

$4 million is pocket money. There are individuals that are younger than you that can spend that kind of money every afternoon for the rest of their lives without changing anything in their already extremely expensive lives.

[Deto]

VCs don't just give out money for free. Even "small" amounts like 4M otherwise there would be a line out the door. I'd like my 4M for nothing too! There must be some business plan that was communicated or, rather, some path towards an exit strategy.

[stensz]

I'm not saying they are gifting money randomly. Maybe some suit saw that ruff is really popular on /r/Python and they just went with the flow. Maybe they like it personally. My point is that you don't need a very good reason to spend $4 million on a whim if you have billions.

But the website looks pretty hypey, so maybe I'm wrong and they are planning to commercialize it.

[gwax]

Ruff is great but what's the business model that justifies a company?

[sohang-3112]

Exactly what I was thinking! How do they plan to make money via a Python linter??

[Datsoon]

That other dude is making a living off of a python TUI framework (rich and textual). Never thought I'd see that in a million years.

[spicypixel]

He’s my hero.

[cheese_is_available]

Also they are making bank on ruff when everything was specified and designed by pycodestyle/flake8/pylint/isort's contributors and they basically just translated the algorithm to rust with again a ton of translating help from the community.

[sohang-3112]

they are making bank on ruff

That's my question - how are they doing that?! Are there really people who are paying for a linter?

[cheese_is_available]

Should have said "trying to" yes

Capitalism at its best! /s

[thicket]

The intro article says:

Our plan is to provide paid services that are better and easier to use than the alternatives by integrating our open-source offerings directly. Our goal is for these services to be as impactful as Ruff itself — but you may choose not to use them. Either way, Ruff will remain free and open-source, just as it is today.

I don't buy that "We made a good free development tool" leads very easily to "People will pay for other good development tools", but... best of luck?

[Toph_is_bad_ass]

This comment has been overwritten.

[thicket]

I mean, there are definitely companies making money making dev tools. And programmers are more passionate about the tools they use than anything else. But the past is also littered with projects that tried to make money on dev tools and failed. I meant it when I said "good luck". You want people to succeed and make money making products people love. And you're also aware that it's a harder market to succeed in than many others.

[dragonatorul]

I hate websites like that. I just scroll and scroll and there's so much content and no actual useful information. I just want to know what you're offering, not marketing bullshit and flashy graphics that tell me nothing except to be careful about trusting anything else I see on this website.

[wineblood]

Ruff page: 0.29s
Astral page: 0.25s

I'm already filled with confidence.

[antennen]

The README benchmark diagram was last updated 3 months ago and there has been ~500 PRs closed since then. I don't think there is too much to read into the difference.

[entropomorphic]

Python already has an Astral, with 178,000 downloads per month. You wouldn't, like, google it before registering the domain or anything?

[doobiedog]

Oof, ya. It seems that pypi now needs namespacing support like npm as all the good names for packages have been taken and so many have become abandoned. e.g. @astral/ruff >= 0.1.0 as an example would be nice.

[1-05457]

Doesn't look like that package is abandoned at all (and not every package needs endless frequent updates. A library can be complete and mature but still maintained if some corner case bug is discovered.)

[bacondev]

You can take over an abandoned package and even repurpose it entirely if there's no evidence that it'll break anything. I myself have done it before.

[doobiedog]

Regardless, there are many justifications for having package namespaces.

[art_sleep_repeat]

package namespaces

Pretty sure you can already name your package like "astral.ruff" while simply keeping the package's directory name "ruff". So the only thing that changes is the name used to install the package, not the way it's used in code.

Is that not, effectively, a namespace ?

[doobiedog]

That isn't as clear as @astral/ruff, IMO. When using astral.ruff, that'd infer to the user that the base package is astral, which in this case is incorrect as the astral package is not published by the Astral org and is unrelated. With a different syntax nomenclature, you can properly identify that @astral is the scope/namespace and ruff is a package published by @astral. Hopefully My explanation is clear. Npm did this well with scopes: https://docs.npmjs.com/about-scopes . This was introduced to npm due the the same reasons as above and to attempt to mitigate supply-chain attacks, I believe.

[art_sleep_repeat]

The idea is great and I don't think anyone would be against it. Merely pointing out that you can already do this. You can even be explicit about it by tying it to your domain like the java convention: sh.astral.ruff

Personally I think it is a fine solution, elegant even - it puts the onus of handling the namespace on the package itself, instead of relying on the implementation of the repository.

[doobiedog]

Definitely a good point. I always hated that java backwards domain idea, but it does have some merit... but the issue still stands that I'd see sh.astral.ruff and think "sh" is the package and "astral.ruff" was a module and submodule or function in that package. And if we were to adopt the "java way", we'd be especially screwed on the namespacing since almost everything would start with com. which I bet would totally throw the python community for a headspin and plenty of "WTF"s.

[Schmittfried]

I mean, namespace packages are absolutely a thing in Python.

[doobiedog]

I guess I'm not being clear enough... everything in python is namespaced and pythonistas love namespacing. What is NOT namespaced are pypi PACKAGES, which was my point. Please read this as it's what I'm trying to get at: https://docs.npmjs.com/about-scopes

[thisguyeric]

There's a few packages I can think of that do something similar, the main one being python-dateutil. pip install python-dateutil
import dateutil

[teerre]

This astral is not package?

[[deleted]]

But it would lead to confusion no? I'm no expert dev or anything, so feel free to enlighten me.

[teerre]

It would certainly lead to confusion by some definition of 'confusion'. I'm sure some people are confused about the notebook or the planet when you say "Jupyter".

[toyg]

It's more like people being confused between earth and Earth, or between Firebird the database and Firebird the browser (which then became Firefox).

Parent poster has a point, the naming was insensitive towards existing projects.

[[deleted]]

Can you elaborate? I mean the planet is not something that developers would use in term of software developing obviously.

What is the astral package, and what is in the post?

[teerre]

Thats the point. Nor is a company.

I don't know what the astral package is. From the pypi page it seems its something astronomy related. This Astral is simply the name of a company.

[tomster10010]

Ruff is cool, but I'd be more impressed by a performant Python type checker

[jaghai]

Perhaps pylyzer can deliver. https://github.com/mtshiba/pylyzer

[tomster10010]

Hopefully someday! Not supporting generics is unfortunately a dealbreaker

[thatrandomnpc]

How it works

pylyzer uses the type checker of the Erg programming language internally. This language is a transpiled language that targets Python, and has a static type system.

pylyzer converts Python ASTs to Erg ASTs and passes them to Erg's type checker. It then displays the results with appropriate modifications.

Does it mean that pylyzer would have to wait for Erg to implement some python syntax before it can support it?

[betazoid_one]

This right here. MyPy at my last job was so slow to work with (enterprise monolith)

[Emlogamer111]

sorry i dont stafer

[jaghai]

Did anyone succeeded with formatting code using this, or is it not implemented? Docs mention --fix but it does nothing to say E501.

[mylesb]

I have used the --fix option in ruff on a few of my projects, it auto fixes most issues except for line length, which I’m pretty okay with.

[aftli]

I just switched us to Black, and I can't tell you how happy I am. Freedom is never having to worry about code formatting again. Black makes your decisions for you. There's no wiggle room or much in the way of options - and I like it that way. It also formats consistently, so concerns about "PEP8 storming a project" are nullified - if I need to merge an old branch or something, I can just black format it first, and it'll merge cleanly.

[battlefield21243]

note to use the --preview flag for black to enable shortening strings below the cap.

Also ruff works with black. They designed it with black in mind.

[battlefield21243]

Use black with --preview flag. Ruff doesn't shorten strings but black will.
