## What it is
Pyflow is a standalone CLI tool written in Rust that manages Python dependency installation and interpreter versions for projects and single scripts. It implements PEP 582 and PEP 518, requiring no pre-installed Python, and supports PEP 723 inline script metadata for one-off scripts.

## Use cases
- manage python project dependencies without pip or venv
- run a python script with dependencies declared inline
- switch python interpreter versions per project
- convert requirements.txt or pipfile to pyproject.toml
- bootstrap python environments on a fresh machine
- publish python packages with a simple workflow

## When to choose
- you want a single standalone binary that handles python installs and dependencies
- you run one-off scripts with inline dependency metadata (PEP 723)
- you prefer PEP 582-style local package directories over virtualenvs

## When to avoid
- your team standardizes on uv, poetry, or pip-tools with existing workflows
- you need lockfile features or workspace support at large-team scale
- you require long-term commercial-grade support for a critical build pipeline
