Flask

Flask is a micro framework framework written in Python that can be used to build APIs, web services and web applications. Flask is designed from the bottom up to be extremely minimal and easy to use, where your whole application can fit into one single Python file. The framework includes no database abstraction layer, form validation, or any other components, by design. However pre-existing third-party libraries provide common functionality needed to build production ready applications and services.

Free & Open Source
👍 Most people think Flask is a good alternative to FastAPI.

Bottle

Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. The framework can be used to create lean web applications with Python 2.7 and 3.x.

This includes things like content negotiation, normalization of node inconsistencies, redirection, and a few others.
