claude-multi-usage 0.8.0

Claude Code usage dashboard across multiple devices

claude-multi-usage (cmu)

CLI dashboard for Claude Code usage tracking across multiple devices.

Parses local ~/.claude data and displays usage stats in your terminal — sessions, tokens, projects, models, and more. Supports multi-device sync via a central server.

Install

Homebrew (macOS)

brew tap hunknownn/tap
brew install claude-multi-usage

pipx

pipx install claude-multi-usage

Usage

cmu                    # Full dashboard (last 14 days)
cmu today              # Today's realtime usage
cmu hourly             # Today's hourly breakdown (tokens/msgs per hour)
cmu projects           # Usage by project (sorted by output tokens)
cmu projects -n 5      # Top 5 projects only
cmu models             # Usage by model
cmu cost               # Monthly cost breakdown
cmu dashboard -d 30    # Last 30 days
cmu dashboard --from 2026-03-01 --to 2026-03-07   # Date range
cmu diff               # All devices (per-device view, via sync server)
cmu diff --merged      # All devices (merged into one view)
cmu diff --key my-key  # Filter by specific key
cmu config show        # Show current configuration

claude-multi-usage also works as a command alias.

Multi-Device Sync

Collect usage data from multiple machines into a central server.

Server Setup

Choose one of the following:

Docker (recommended)

docker run -d -p 8000:8000 -v cmu-data:/data ghcr.io/hunknownn/claude-multi-usage:latest

Kubernetes

kubectl create namespace cmu-server
kubectl apply -k https://github.com/hunknownn/claude-multi-usage/deploy/k8s/ -n cmu-server

To expose via Ingress (optional):

curl -O https://raw.githubusercontent.com/hunknownn/claude-multi-usage/main/deploy/k8s/ingress.example.yaml
# Edit the file — replace your-domain.example.com with your domain
kubectl apply -f ingress.example.yaml -n cmu-server

pip

pip install claude-multi-usage[server]
cmu server start --host 0.0.0.0 --port 8000

Client Setup

# Set server URL and key (once per device)
cmu config server https://your-server.com
cmu config key add my-key "personal usage"

# Set device alias (optional, for readable display names)
cmu config alias macbook-air

# Sync usage data
cmu sync

# View all devices' usage
cmu diff               # Per-device view
cmu diff --merged      # Merged into one view
cmu diff --key my-key  # Filter by specific key

Keys are used to group devices. Only devices with the same key can see each other's data. Local commands (cmu dashboard, cmu today, cmu cost, etc.) work without keys.

Auto Sync

Add to ~/.zshrc to sync automatically when using Claude:

cc() {
    cmu sync --quiet &>/dev/null &
    command claude "$@"
    cmu sync --quiet &>/dev/null &
}

The function name cc is just an example — you can use any name you prefer (e.g., cl, claude-sync). If you already have alias cc="claude" in your shell config, replace it with the function above and remove the alias line to avoid conflicts.

Devices with an alias show as alias (hostname). Devices without an alias show hostname only. Today's hourly usage is shown per device when available via cmu sync.

Cost Estimation

Calculates estimated API costs using LiteLLM's pricing DB (2,600+ models). Pricing is auto-fetched and cached locally for 24 hours.

• Supports tiered pricing (200K+ token extended context)
• Subagent (haiku) usage included
• Deduplicates streaming message blocks
• Falls back to last cached pricing when offline

How It Works

Reads local Claude Code data from ~/.claude/:

• stats-cache.json — daily activity, model tokens, hourly counts
• projects/**/*.jsonl — session files per project (including subagents)

No API keys required. Local data stays local unless you opt in to sync.

Roadmap

• Multi-device sync via central server (#2)
• Accurate cost estimation with incremental caching (#5)
• Key-based device grouping with alias support (#8, #11)
• cmu diff — multi-device per-device/merged view (#11)
• cmu hourly — today's per-hour usage breakdown with sync support
• Homebrew support
• Web dashboard (#3)
