Claude Tokens

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

Features

• Menu bar only — no dock icon, no main window, always one click away
• Live cost tracking — reads Claude Code's local data files and estimates costs per model (Opus, Sonnet, Haiku)
• Rate limit display — shows remaining token % via the Anthropic API with a dynamic menu bar icon
• Per-project breakdown — last-session costs for each Claude Code project
• Privacy-first — all data is read locally; nothing is sent except lightweight rate limit polling

Setup

1. Build and publish:

   ./publish.sh

2. Copy to Applications:

   cp -R "publish/Claude Tokens.app" /Applications/

3. (Optional) Add to System Settings > General > Login Items for auto-start.
4. To enable rate limit display, add your Anthropic API key to ~/.claude-tokens/settings.json.
