We have a product that depends on data received from external web services. We often want to test certain conditions in the data (specific results, error scenarios, etc), and it's difficult or impossible to guarantee these conditions when we call out to our external services. We use mitmproxy to intercept and manipulate the responses we get.

Even if we don't need to manipulate the data, it's a very useful tool for watching requests go back and forth.
