Does uv replace the need for pyenv?

Yes, uv has built-in Python version management. It can download, install, and manage multiple Python interpreters, often making tools like pyenv redundant.

Is uv really faster than pip and Poetry?

Yes, uv is written in Rust and is designed to be 10-100x faster than pip. It uses a sophisticated global cache and a high-performance resolver to significantly reduce installation times.

Can I use uv with my existing pyproject.toml?

Absolutely. uv is highly compatible with standard Python packaging standards (PEP 517/621) and can work directly with your existing pyproject.toml files.

How does uv ensure reproducible builds?

uv uses a lockfile (uv.lock) to track exact dependency versions and hashes, ensuring that every environment—from local development to production—is identical.
