Hatch vs setuptools

Hatch is a free, MIT-licensed Python project manager for creating projects and managing development environments on Linux, macOS, and Windows. It can start projects from templates or initialize existing ones, including migrating setuptools configuration from setup.py. Environment management supports custom scripts and UV, with manual Python installations or automatic installation as part of an environment. Hatch also supports reproducible builds, test execution, and static analysis backed by Ruff. For publishing, it can upload packages to PyPI and other package indices; lockfiles, dependency groups, and private registries are listed capabilities. Its plugin system uses pluggy, with documented extension types for environments, builders, publishers, and other project tasks. Visual Studio Code can discover Hatch environments through the vscode-python extension, and an official GitHub Actions install action is documented. Installation options include standalone installers or binaries, pip, pipx, Homebrew, Conda, and other methods. The documentation provides a self-report command that prepares a GitHub issue for unexpected behavior.

setuptools is a free Python packaging library for preparing projects for sharing and installation. It can serve as a project build backend, discover packages and namespaces, and let maintainers control which packages are distributed. It handles build-system requirements plus required and optional dependencies, including version limits and environment markers, and supports dependency groups. Configured entry points can generate console-command and plugin scripts during installation. Editable installs apply source changes without rebuilding and reinstalling. The library can build C and C++ extension modules, and its documentation covers workflows with pip, build, and PyPI. Setuptools runs on Linux, macOS, and Windows, while the current PyPI listing requires Python 3.10 or later. The project identifies modern PyPA-standard APIs and documented customization APIs as its most stable interfaces. It is free, has no free trial, and professional support is available through a Tidelift Subscription.
