Summary: Frugon is a local LLM cost analyzer that tells you exactly where your LLM bill is leaking and which cheaper model could handle each call. Point it at your OpenAI-format JSONL logs and it prices every call against candidate models locally — no LLM calls, no network. Features: cost analysis, proxy shim capture (frugon capture), routing recommendations, quality visibility (--measure), and shareable reports. MIT licensed.

Relevance to LLMOps/infra: Essential ops tool for any team using LLMs in production. Frugon answers the fundamental cost-optimization question: “which calls can I route to a cheaper model without sacrificing quality?” It’s the analysis side of the LLM gateway/routing stack.
