Combined Claude + Codex token usage and cost tracking CLI

AI Usage Tracker

A comprehensive token usage and cost tracking tool for Claude Code and Codex CLI.

Overview

This tool combines usage data from both ccusage (Claude) and ccusage-codex (Codex) to provide a unified view of your AI token consumption and associated costs.

Quick Start

Install via pip (Python)

pip install ai-usage-tracker
ai-usage-tracker

Install via npm (Node.js)

npm install -g ai-usage-tracker
ai-usage-tracker-js

Install from source

git clone https://github.com/jleechanorg/ai-usage-tracker.git
cd ai-usage-tracker

# Install dependencies (ccusage and ccusage-codex)
./scripts/install-dependencies.sh

# Run the report
python3 scripts/combined-usage-report.py

# Or install as a Claude skill
ln -s $(pwd)/.claude/skills/combined-usage ~/.claude/skills/combined-usage
# Then use: /combined-usage

Features

• Combined Reporting: View Claude and Codex usage side-by-side
• Cost Analysis: Track spending across both platforms
• Daily Averages: Calculate average usage over time
• Cache Efficiency: Monitor cache read rates and savings
• Flexible Output: Table format for humans, JSON for automation
• Claude Skill: Invoke directly from Claude Code CLI
