Viable alternative to gunicorn on Windows

[millsks]

We are inheriting a project that we need to keep on Windows for a few cycles until new infrastructure is stood up. We are migrating a flask app to django and using cookiecutter-django as our template. For production what would be considered a viable alternative to gunicorn on Windows? We see waitress as an option, but wanted to get feedback from the cookiecutter-django community before we make a decision.
