ActiveState Platform vs setuptools

ActiveState Platform hosts custom runtimes assembled from source. Projects specify runtime components, preserve project history and provide deployment instructions; their artifacts may include packages, dependencies, patches and bundles, but not contributors’ first-party code. Create projects in the web interface or with the State Tool CLI, then deploy and activate them locally. Projects can remain personal, be shared with an organization or be public. The platform supports Windows, macOS and Linux deployments, and its GraphQL API can build open-source software for different operating systems and languages without requiring users to manage build infrastructure. It provides immutable SBOMs in SPDX formats and describes build safeguards including reproducible builds, checksum checks and isolated containers. A free organization plan costs nothing and is limited to public projects. Curated Catalog annual pricing is $25,000 for fewer than 100 employees, $50,000 for 100–999 employees and $150,000 for 1,000 or more; those prices do not apply to legacy Platform subscriptions.

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.
