In their own words
Twine
Twine publishes already-built Python package distributions to PyPI, TestPyPI, and other configured repositories, including private registries. It uploads source and binary files independently of the build system, so uploading does not require it to run setup.py. Twine accepts packaging formats including wheels, and its check command checks whether a distribution’s long description will render correctly on PyPI. It authenticates to PyPI over HTTPS using a verified connection, can sign files with GPG, and can upload files signed in advance. Repository settings can be supplied in a.pypirc file, command-line options, or environment variables, which can be useful on CI and build servers. Twine can store repository usernames and passwords with keyring, though headless Linux systems may need extra setup to store secrets securely. The package requires Python 3.10 or later, is licensed under Apache-2.0, and supports Linux, macOS, and Windows. Its plan is free. Twine is classified for developers and handles package publishing, but does not provide lockfile support, environment management, or dependency groups.
