Yes, it's faster and better than pyenv, but the mechanism it's using (virtual environments) is not a uv invention.

uv does the Python ecosystem better than any other tool, but it's still the standard Python ecosystem as defined in the relevant PEPs.



Are the lock files standardised, or a uv-specific thing?


uv has both a uv-specific implementation, and support for standard PEP 751 lockfiles


Worth noting uv-specific implementation has more features than that standard PEP 751 lockfiles, so uv plans to keep using its own implementation by default. https://github.com/astral-sh/uv/issues/12584
