Why was this tool discontinued?

Automatically marked inactive after 7 consecutive failed health checks (last error: DNS resolution failed)

What It Does

The tool functions as an intermediary proxy, intercepting and logging all API requests and responses to various LLM providers. It then processes this data to generate detailed analytics on token consumption, latency, error rates, and costs, broken down by project, user, and specific models. This self-hostable architecture ensures that all sensitive API usage data remains within the user's controlled environment.
