barcc

A native macOS menu bar app that tracks Claude Code usage and costs in real-time.

What it does

Parses Claude Code's JSONL logs from ~/.claude/projects and displays:

• Real-time token consumption (input/output/cache)
• Estimated costs per model
• 30-day usage chart
• Daily breakdowns with model-specific stats

Features

• Color-coded cost indicator — green/yellow/orange based on daily spend
• Multi-model support — Sonnet 3.5/4.5, Opus 4.5, Haiku 3.5
• Auto-refresh — Updates every 30 seconds
• Screenshot export — Save stats as PNG
