"ruff" for Python which is displacing the flake8 linter (and in fact the "black" code formatter too) shows that this kind of thing can work fantastically well.

I am hoping that ruff goes after type checking next to replace mypy which is pretty slow. One tool to rule them all

  they've successfully replace pylama and black so yeah I really hope it's their next target (though handling types is a whole different beast altogether)

  Have you checked out Pyright[1]? It's not one tool to rule then all, but it is nice and fast. [1]https://github.com/microsoft/pyright https://github.com/microsoft/pyright

    Pyright is neat but the CLI output makes me want to poke my eyes.

  dmypy [0] (installed when you install mypy) will give you a x10 speedup when running mypy after small regular edits (e.g. during general development). But yeah, I'm also looking forward to the day when I only need a single speedy tool for python linting, type-checking and formatting. 0: https://mypy.readthedocs.io/en/stable/mypy_daemon.html https://mypy.readthedocs.io/en/stable/mypy_daemon.html

  Have you by any chance used Pyright? If not, I can highly recommend it. The VS Code extension makes writing Python almost as if it's a statically typed language (+ there is a CLI if you want to check types in CI). The docs are claiming that it's 3-5x faster than mypy - I haven't run performance benchmarks myself, all I can say is that for all my code bases it is very fast after the first cold start.

Ruff is better than flake8 for reasons other than speed. 1) it works better as an lsp/vscode plugin, so I don't need to save to get errors popping up. 2) it respects pyproject.toml and doesn't need to liter my root dir with another dot file. 3) as an intangible, its errors just feel better.
