# Full TUI with burn-up chart (default)
ccburn

# Weekly usage view
ccburn weekly

# Compact output for tmux/status bars
ccburn --compact
# Output: Session: 🔥 45% (2h14m) | Weekly: 🧊 12% | Sonnet: 🧊 3%

# JSON output for scripting/automation
ccburn --json

Pace Indicators

Emoji	Status	Meaning
🧊	Behind pace	Usage below expected budget — you have headroom
🔥	On pace	Usage tracking with expected budget
🚨	Ahead of pace	Usage above expected budget — slow down!

Requirements

• Python 3.10+
• Claude Code installed with valid credentials
• Terminal with Unicode support (for charts and emojis)

How It Works

ccburn reads your Claude Code credentials and fetches usage data from the Anthropic API. It calculates:

• Budget pace — Where you "should" be based on time elapsed in the window
• Burn rate — How fast you're consuming your limit
• Time to limit — Estimated time until you hit 100% (if current rate continues)

Data is stored locally in SQLite for historical analysis and to minimize API calls when running multiple instances.

Troubleshooting

"Credentials not found"

Ensure Claude Code is installed and you've logged in at least once:

claude  # This will prompt for login if needed

Chart not displaying correctly

Ensure your terminal supports Unicode and has a monospace font with emoji support. Recommended terminals:

• Windows: Windows Terminal
• macOS: iTerm2, Terminal.app
• Linux: Kitty, Alacritty, GNOME Terminal

Stale data indicator

If you see "(stale)" in the header, ccburn couldn't reach the API. It will continue showing cached data and retry automatically.
