cc-logger

Export and analyse Claude Code sessions.

Reads the JSONL trajectories Claude Code stores in ~/.claude/ and converts them to Harbor ATIF format for viewing and analysis. Includes cost estimation using Anthropic's model pricing.

Install

pip install claude-code-logger

Usage

# List sessions
cc-logger list

# Export all sessions (Harbor format by default)
cc-logger export /tmp/cc-export

# View exported sessions in the browser
cc-logger view /tmp/cc-export

# Show analytics (tokens, costs, models, working hours)
cc-logger stats /tmp/cc-export
cc-logger stats /tmp/cc-export --json

# Refresh model pricing from Anthropic
cc-logger update-pricing

Pricing

Cost estimation uses model pricing bundled in src/cc_logger/data/pricing.json, scraped from platform.claude.com/docs/en/about-claude/pricing.

Run cc-logger update-pricing to scrape the latest prices into the repo, then release a new version so users get updated pricing.
