Another one I recently discovered and that has a very active maintainer is "zuban" or zuban-ls. It has replaced jedi-language-server for me, and aims to replace mypy as well.

Yeah, there are now 3 competitors and they all written in Rust:
- zuban
- ty (from ruff team)
- pyrefly
One year ago, we had none of them, only slow options.
Speed is one of those "Quantity has a quality all its own" things. We use very fast tools in a qualitatively different way, even though all that changed was how long it takes in seconds.
It is interesting that nobody was writing these tools in C or in C++. There are obvious ergonomic reasons, but perhaps also it matters that Rust cares a lot more about types than either of those languages.

This one's easier to explain. People interested in tooling for a specific language probably want to write that tooling in that language (hence pip, poetry, mypy, jedi, etc). Normally that would be the end if it, if Python wasn't 10-100x slower than a natively compiled language. And going from Python to Rust is an order of magnitude easier than going from Python to C or Python to C++, because the compiler is so good at identifying silly mistakes. Rust is just a friendlier language.
It's just very hard to write such systems in C/C++. Even all these Rust versions are segfaulting and panicking quite a lot. So many corner and edge cases that can be found in Python code, and the memory handling is also hard.
The author of Zuban started writing it back in 2020 or 2021, so it took him more than 4 years to complete it. And he is the author of Jedi, so he had prior experience already.

Basedpyright is not rust but it's a fork of pyright with added features that are otherwise locked in vscode
It's written in Typescript, which is a super weird choice.

I'm sorry, I can't take seriously any piece of software which decided to prefix the previous version's name with "based". I'm aware this is a me problem.

It's also horrible for fasle positives unless your project happens to be the exact same setup as the maintainers' - I had to turn off the actual type checking on it. I've since moved wholesale to the Ty alpha and it feels a hell of a lot smarter.

it'll be like python package managers and js web frameworks.... a new one every quarter
uv works so well for the vast majority of scenarios that I don't really see a demand for further innovation in the Python package manager domain.
