Builds and switches between multiple Python versions. The listings below can replace it for an important use case. Each note says what changes if you switch.

The original

Replacements

Listings that take over the same core job as pyenv.

  • uv

    A single Rust tool that replaces pip, pipx, poetry, pyenv, virtualenv and twine, and installs packages 10 to 100 times faster.

    uv installs and manages Python versions itself and also replaces pip, pipx, poetry and virtualenv, running on Windows too without compiling Python from source.

  • asdf

    One version manager for many language runtimes.

    asdf manages Python alongside many other runtimes through plugins and one .tool-versions file, while keeping a similar shim approach that can confuse tooling.

  • mise

    Keep project tools, environment variables and tasks in one configuration.

    mise handles Python and other tool versions together with environment variables and project tasks in one configuration, and it supports Windows as well as macOS and Linux.
