Key Features

• Project management with lockfiles, workspaces, similar to rye or poetry
• Script running with inline dependency metadata
• Install and manage Python versions
• Run and install tools published as Python packages
• pip-compatible interface with familiar CLI
• Cargo-style workspaces for scalable projects
• Global caching for disk-space efficiency
• Install via curl or pip without Rust or Python required
• Supports macOS, Linux, and Windows

Target Audience

• Python developers seeking faster package management
• Users migrating from poetry, pipenv, and similar tools
• Developers needing unified management of Python versions, dependencies, and projects
