🛠 Lupen Released — A macOS app for detailed expense tracking of Claude Code and Codex
The program analyzes local session log files, providing a cost breakdown for every step (turn), tool, and sub-agent. This allows users to verify expenses based on token data.
🌍 The emergence of tools for transparent cost control of AI agents is becoming critically important as agentic workflows grow more complex, where a single request can trigger dozens of hidden sub-requests.
👤 It helps avoid unpleasant surprises in bills from Anthropic or OpenAI by allowing users to understand exactly which operation or "runaway" sub-agent consumed the budget.
