## What it is
PDM is a modern Python package and dependency manager that supports the latest PEP standards (PEP 517, 582, 621) and manages project dependencies, virtual environments, and Python interpreters. It offers a fast dependency resolver, a PEP 517 build backend, a plugin system, and an optional pnpm-style centralized installation cache.

## Use cases
- manage python project dependencies with a lockfile
- replace pipenv or poetry for dependency management
- manage pyproject.toml metadata per PEP 621
- install and manage multiple python interpreters
- build and publish python packages
- save disk space with a centralized package cache

## When to choose
- you want a modern PEP-standards-compliant alternative to Pipenv or Poetry
- you need fast resolution for large binary distributions
- you want a flexible plugin system and versatile user scripts
- you want to install and manage Python versions alongside dependencies

## When to avoid
- you are already satisfied with Pipenv, Poetry, or uv
- you need a tool for non-Python ecosystems
- your environment must run Python below 3.9/3.10 for the manager itself
