CC-Ledger: Claude Code Cost Tracker (Per-Session and Per-PR) (github.com)

The announcement of CC-Ledger introduces a local-first ledger for tracking coding-agent activity in Claude Code, allowing users to monitor per-session and per-pull request (PR) token costs. All edits, prompts, and token expenses are logged onto the user's machine without ever uploading sensitive raw data to the cloud unless explicitly opted-in. CC-Ledger supports functionalities such as aggregating costs per PR and presents a simple command-line interface for installation and usage, with a macOS menubar companion for quick access to statistics. This tool is significant for the AI/ML community as it emphasizes data privacy while providing detailed insights into coding costs associated with using AI agents. Developers can track their usage metrics without compromising sensitive information, enhancing accountability and budgeting in AI-assisted coding workflows. The system supports several environment configurations, optimizing usability across various platforms, and will eventually allow integration with other coding agents like Cursor and Codex, broadening its applicability in development environments.
