llm.log

A local proxy that sits between your apps and LLM APIs. It intercepts requests, extracts token usage, calculates costs, and stores everything in SQLite, without changing a single line of code.

• Zero code changes: works via HTTPS_PROXY, picked up by most apps automatically. Supports OpenAI, Anthropic, and OpenRouter.

• Real costs: auto-updated pricing for 780+ models, cache token breakdowns. Claude Code aware, so you can see what you'd pay on API keys vs subscription.

• TUI dashboard with overview, charts, cost breakdown, and request inspector. Export to CSV, JSON, or JSONL for analysis.

• Single binary, pure Go, no dependencies. Minimal overhead: logging is async and never blocks your requests.
