Python

It comes with built-in ruff and uv, and can handle Python versioning for you!

Not sure if they want to eventually dissolve Rye into uv or what, but for now it's one of the best (better than Poetry, IMO)

edit: it also uses the pypoetry.toml standard, something Poetry doesn't (because Poetry predates pyproject.toml becoming a standard).

One possible downside: I've heard Rye doesn't honor XDG, which means it has its own location for its config. I don't mind, but perhaps you do.

A second possible downside is that Rye doesn't let you centralize your venvs, so each .venv goes into each project folder, so no using virtualenvwrapper with workon to jump between projects. zoxide can alleviate that problem, or presuming you have a ~/dev folder or similar, you could write a bash function that ls' that folder and lets you select a folder via fzf? Go ask ChatGPT about it or something.
