history

Project history and usage

PDM is a Python package and project manager that manages dependencies, lockfiles, environments, scripts, builds, and publishing through modern Python packaging standards.

Project history

PDM was created around support for PEP 582's project-local `__pypackages__` layout. The project expanded beyond that origin into a full Python project and dependency manager supporting current packaging standards.

The 0.12 release line in late 2020 improved `pdm run`, exporting, Windows PEP 582 integration, and lockfile metadata. Version 1.0 followed in January 2021. Later development made virtual environments the default, broadened dependency groups, publishing, workspaces, interpreter management, and lock strategies, and introduced experimental use of uv as a resolver and installer.

Adoption history

PDM gained adoption as Python packaging moved toward `pyproject.toml`, standardized build interfaces, declarative metadata, and lockfile-based workflows. The supplied mappings record packages in Homebrew, Debian, and Nix.

Its continued support for both virtual environments and the PEP 582 `__pypackages__` layout helped distinguish it early on. After PEP 582 was rejected, PDM retained that mode as an opt-in feature while making conventional virtual environments the recommended default.

How it is used

A typical workflow begins with `pdm new` or `pdm init`, adds dependencies with `pdm add`, records exact resolutions in `pdm.lock`, installs or synchronizes an environment with `pdm install` or `pdm sync`, and runs project commands with `pdm run`.

Library maintainers can build and upload distributions with PDM's build and publish commands. Teams generally commit `pdm.lock` when they want development and CI to reproduce the same resolution.

Why package nerds care

PDM is significant in Python package-manager culture because it combined standards-oriented project metadata, dependency resolution, locking, environment management, script execution, building, and publishing in one CLI.

Its history captures a transitional period in Python packaging: enthusiasm for PEP 582, consolidation around `pyproject.toml`, greater use of reproducible lockfiles, and later cooperation with high-performance tooling such as uv.

Timeline

2020: The 0.12 release line expanded scripts, exporting, PEP 582 integration, and lockfile handling.
2021-01-05: PDM 1.0.0 was released.
2023: Virtual environments were established as the recommended mode after PEP 582's rejection.
2025: PDM documented experimental uv-backed resolution and installation.
