LiteLLM provides a way to call more than 100 language models through an OpenAI-compatible interface.
F You, Show Me The Prompt
Quickly understand inscrutable LLM frameworks by intercepting API calls.
About F You, Show Me The Prompt
This is a blog post that explains how to use mitmproxy, a free open-source HTTPS proxy, to log outgoing LLM API requests and view the final prompts sent by frameworks. It covers installing mitmproxy, starting the mitmweb interface, routing device traffic through localhost port 8080, and using examples from tools such as guardrails, guidance, instructor, langchain, and DSPy.
It also describes two types of automation — interleaving code with LLMs and rewriting prompts — and suggests reviewing prompts and call counts to decide if a framework is needed, if the prompt can be reused directly, or if it can be improved.
Key features
- Log outgoing LLM API requests through a proxy
- View final prompts sent by LLM frameworks
- Set up mitmproxy and mitmweb interactive UI
- Route device traffic via localhost port 8080
- Compare prompt construction across guardrails, guidance, instructor, langchain, DSPy
- Evaluate framework necessity from prompts and call counts
Best for: Developers evaluating LLM libraries who want to see the actual prompts sent to models.
Good for
- Works across tools without reading source code or docs
- Explains tool behavior through actual prompts sent to models
- Supports decisions about keeping, replacing, or improving prompts

F You, Show Me The Prompt FAQ
How can I see the prompts a framework sends?
Set up a proxy that logs outgoing API requests with mitmproxy, rather than patching code or searching docs.
How do I start mitmproxy's interactive interface?
Run mitmweb in the terminal and open the web server URL shown in the logs, such as http://127.0.0.1:8081/
How do I route traffic through mitmproxy?
Configure your device to use an HTTP proxy at localhost port 8080, then visit http://mitm.it
