I have no relation with the Astral team but have been an early and aggressive adopter of everything they've released and it's all been easy, fast, and ergonomic. Over the past eighteen months I've:

1. Replaced `flake8` with `ruff`;

2. Replaced `black` with `ruff`;

3. Replaced `pip` with `uv`;

4. Replaced `poetry` with `uv`.

Their next project appears to be exactly what I _wish_ their next project to be — a replacement for pyright et al (https://github.com/astral-sh/ruff/discussions/10581). Type checking is my least favorite part of my Python toolchain at the moment; I can't wait to take it for a spin.

Pyright was itself a big improvement over Mypy. Just look at this for starters: https://htmlpreview.github.io/?https://github.com/python/typ...

If Astral can leapfrog Pyright too, great. But I think it will be significantly harder than leapfrogging Flake8 and Black was.

What benefits does uv have over poetry?

[dagw]

In addition to what everybody else has mentioned, uv plays nice with other people's build tools. I use scikit-build-core for building most of my python packages and making scikit-build-core play nicely with poetry was somewhere between very hard and impossible. UV trivially lets me combine the two so I can let uv do what it does best (manage and install python versions and dependencies) and then have it get out of the way and let scikit-build-core take over and do what it does best.

[jasongill]

uv also manages the Python version as well, and it doesn't require jumping through hoops and hacking to get it to play nicely with Docker. uv is much more of a production-ready setup than pip or poetry from my experience moving to uv over the last few weeks

Speed, compatibility, ergonomics, standards compliance.

Works with pytorch.

Pylance is nicer than pyright, but unfortunately I don't think you can use it outside of vs code

[joshSzep]

pylance is pyright under the hood, isn't it? it's the main reason I use pyright over mypy: I work in VSCode and I want compatible type checking

[anentropic]

It's not clear to me that they are building an alternate type checker per se

Seems like `ruff server` is an LSP?

[baggiponte]

Yes but only for linting (the flake8 rules etc). The end goal is to have proper type checking and, I think, proper LSP refactoring capabilities.

[baggiponte]

they are working on it! the internal name is currently red-knot (you can see it in their GH History and in the discord). First thing is a type checker, I think, then the renaming capabilities and such.

[antman]

True, what I would really need is a uv based pyinstaller alternative
