What is Respan AI?

Respan AI is a tool for managing and monitoring large language model traffic across your applications. It sits between your application and LLM APIs, allowing you to route requests, track usage, and identify issues in real time. The tool is designed for developers and teams building with LLMs who need visibility into what's happening with their model calls. It captures request and response data, making it easier to debug problems, optimise prompts, and understand how your LLM integration is performing. Since it's available as a free tier, it's accessible for small projects, startups, and teams evaluating their LLM infrastructure.
