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
