It’s great to see that Mitmproxy is still being developed - it indirectly made my career.<p>Back in 2011, I was using it to learn API development by intercepting mobile app requests when I discovered that Airbnb’s API was susceptible to Rails mass assignment (<a href="https://github.com/rails/rails/issues/5228">https://github.com/rails/rails/issues/5228</a>). I then used it to modify some benign attributes, reached out to the company, and it landed me an interview. Rest is history.
