Native macOS menu bar · Open source · Free
Track your AI-coding token burn. Privately.
Claude Code and OpenAI Codex burn real tokens and real dollars — you just can’t see how much. Burnbar puts the number in your menu bar, read straight from the local CLI logs on your Mac. Never your browser, never your Keychain, never your code.
Most trackers spy to count
There’s an easy way to see your AI usage, and a right way. The easy way reads your browser cookies and digs through your Keychain. Burnbar refuses to.
No browser snooping
Trackers like CodexBar read your browser cookies and dig through your Keychain just to fetch your numbers. Burnbar never touches either — it reads only the local CLI logs Claude Code and Codex already write to ~/.claude and ~/.codex.
Your data stays on your Mac
No account, no analytics, no server quietly collecting your usage. Everything is computed locally. The only thing that ever leaves is a tiny daily summary — and only if you choose to join the leaderboard.
One number, zero clutter
A native macOS app — not an Electron tab, not a dashboard you have to babysit. It shows your burn in the menu bar and gets out of the way. Open it and you’re done.
Burnbar vs. browser-based trackers
Same glanceable menu-bar number. A completely different deal with your privacy.
| Capability | Burnbar | Browser-based trackers |
|---|---|---|
| Reads only local CLI logs | Yes | No |
| Leaves your browser cookies alone | Yes | No |
| Never touches your Keychain | Yes | No |
| Your usage never leaves your Mac * | Yes | Not applicable |
| Native, single-purpose menu-bar app | Yes | Yes |
* Your usage never leaves your Mac apart from the optional daily leaderboard summary, which uploads only if you opt in.
How it works
Reads local logs
Burnbar parses the usage logs Claude Code and OpenAI Codex already write to ~/.claude and ~/.codex. Token counts, models, and timestamps only — never your prompts or code.
Syncs across devices
Per-machine rollups sync privately through your own iCloud Drive, so usage from every Mac you code on adds up in one place. Nothing touches a Burnbar server.
Opt-in leaderboard
Choose to share, and Burnbar uploads a tiny daily summary to climb the global leaderboard. Off by default, and you decide every time.
The privacy promise
Privacy is the whole point. Burnbar measures your usage without ever seeing what you build.
- Local CLI logs only
- Burnbar reads only Claude Code and OpenAI Codex logs under ~/.claude and ~/.codex on your machine.
- Never your browser or Keychain
- No browser cookies, local storage, or third-party Keychain items. Burnbar touches only its own credentials.
- Never your content
- Prompts, code, project names, file paths, and git details are never read for upload — only counts, models, and dates.
- Minimal opt-in upload
- If you join the leaderboard, Burnbar sends only { date, provider, tokens, cost } — no prompts, paths, project names, machine ids, or raw model names.
