Your LLM bill
is leaking.

Most teams run every call on their most expensive model. Frugon reads your real logs locally and shows which calls a cheaper model handles just as well, and which to leave alone. No upload. No telemetry.

why you can trust the number

Three small things, done correctly.

Frugon assembles existing tools. It does not invent. The boring parts are where credibility lives.

Counts tokens with tokencost. Prices with LiteLLM.

Nothing original here. That's the point. The LiteLLM pricing registry updates weekly so the math doesn't rot.

Quality anchored to RouteLLM / LMSYS bands.

We will not round up. If --measure contradicts the projection, the report says so plainly.

pipx, uvx, or pip.

macOS, Linux, Windows. Python 3.10 → 3.13. No accounts, ever. Nothing else to install.

verifiable in the source

Your data never leaves your machine.

Frugon collects nothing.

Token counting, pricing, and arithmetic all run on your machine. With --measure, your sampled prompts go to your providers using your keys. Nothing else. There is no Frugon endpoint in the path of your data.
