What are the differences between Rye and Pixi?

[linhduongtuan]

As far as I know, Rye and Pixi are quite similar?

To give some context, pixi is a new package manager for Python, for the conda ecosystem. Version 0.1.0 was just launched a couple of days ago, see https://prefix.dev/blog/launching_pixi. It looks quite nice.

So far I think they do not support pip packages yet, but it's in their pipeline to do so.

I would also be curious to know people's opinion on it, and how it compares to rye.

On this topic, I also found out about huak, which is another Python package manager written in Rust. I don't know how mature it is. It seems to behave similarly to Hatch/PDM/Rye, but doesn't manage the Python toolchain itself.

there is a package for Pypi packages from pixi.

https://github.com/prefix-dev/rip

is there any plan to use rip instead of pip-tools?

They are not similar. Pixi is "higher-level" and uses the conda ecosystem to deal with packages in a language-agnostic way. Rye is just to manage Python projects.

Potentially, you could use them together.

I guess one of the main differences is that pixi is conda based and uses a custom pixi.toml to manage the environment. Rye follows PEP standard (uses venv, pip, pip-tools under the hood) and pyproject.toml with standard tags (exception of it's own tool section).

I guess it would be nice to have some sort of "official" note explaining the differences between the two tools, from an end-user standpoint. Like perhaps a blogpost or something. So far for me both have been kind of equivalent, though sometimes rye seems to behave better so I tend to use it more (though I don't really understand why).

By "official" I mean coming from the developers of the tools, since probably they understand better their roadmap, current and future features, where the tools are similar/different today, and in the future.

Generally, some guidance in choosing one or the other would be nice.
