I recently worked on a retail recommendations app and needed a unified workflow for logging and caching. Most solutions I found were either reliant on monkey patching, difficult to deploy, or too expensive. So, I built a simple stand-alone proxy server that runs on my laptop. It helps me debug, track costs, and collect traffic for model fine-tuning.

I've been developing this proxy for several months, and a few friends are already using it. I'm looking to scale it up and would love feedback from the community. Please share your thoughts, questions, or comments.
