setuptools vs Spack
Both stand on python package managers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacWindows
Choose setuptools if you need a free Python packaging library with package discovery, dependency configuration, entry points, and support for C or C++ extensions. Look elsewhere if your required features include lockfile support, environment management, or package publishing.
