Rip (https://github.com/prefix-dev/rip/issues) which is more of a library for other rust tools to be on top of like Pixi (which is looking to replace both Pip and Conda).
And now uv, which seems to be looking to replace Pip, Pip-Tools, and eventually Poetry and PDM.
A lot of the explosion in tools in the Python world is coming from the desire for better workflows. But it has been enabled by the fact that build configuration and calling has been standardized and tool makers are able to follow standards instead of reverse engineering easy install or setup tools.
I know a lot of people are put off by there being so many tools, but I think in a few years the dust will settle and there will emerge a best practice work flow that most users can follow.
As a primarily Python developer and someone who occasionally contributes to Pip to solve complex dependency resolution issues it does make me wonder if I should hang my hat on that and learn enough rust to contribute to one of these projects eventually.
