WHOOP for token burn. See the API-value cost of every token you burn in Claude Code and Codex, then compare today, this week, and this month with a private crew of friends. No accounts, no global leaderboard, no prompts ever leave your Mac.

Highlights

  • 🔥 Menu bar app (macOS 14+, ~1.3 MB): today's burn in the bar; burn calendar, 14/30/90-day trend, hour-of-day rhythm in your timezone, and gym-style personal records
  • 📊 By-model costs for today / week / month, with hover token detail and a fast/standard split
  • 👥 Private pits: invite-code crews on a self-hosted Cloudflare Worker (free tier), emoji avatars, weekly-king crown, editable display names on permanent handles
  • ⚡ Fast engine: 8.9 GB of history scans in ~8s once, ~0.1s warm

Privacy, exhaustively

What leaves your machine when you join a pit: pit code, handle, display name, a random machine ID, UTC date, token count, USD cost, Claude/Codex cost split, and per-model token/cost aggregates. Never: prompts, file paths, repo names, session content, or timestamps finer than a day. Nothing at all leaves if you never join a pit.

Full details in the CHANGELOG.
