Pacer

Pacer

Know what Claude Code is costing you — and how close you are to your limits — right from your Mac's menu bar.

Pacer is a free, open-source macOS app that keeps an eye on your Claude Code
usage: the tokens you're burning, what they cost, how close you are to your
5-hour and weekly rate limits, and where the spend is going — by project, by
model, by day. It sits quietly in your menu bar, keeps itself up to date, and
keeps all of your data on your own Mac.

      Menu bar & click-down popover

      Home-screen & Notification Center widgets

  Share your 5-hour & 7-day burn charts as an image

More screenshots — models, projects & collections, six-month history

  Models — share, trend, and per-model table; group by model or class

  Projects & Collections — group projects, scope totals to a collection

  History — lifetime totals, six-month heatmap, monthly spend
Heads up — early days. Pacer is pre-1.0 and under active development. It
works and it's useful today, but expect the occasional rough edge, and your
saved history may need to be rebuilt between 0.x versions.

Download & install

1. Download the latest version →
   (grab the Pacer-x.y.z.dmg file under "Assets").
2. Open the downloaded file and drag Pacer into your Applications folder.
3. Launch Pacer. It lives in your menu bar — look for the little gauge icon
   up top (there's no Dock icon). Click it to open the dashboard.
4. The first time, macOS asks permission for Pacer to read Claude Code's files.
   Click Allow — that's how Pacer sees your usage. It stays on your Mac.

Or with Homebrew:

That's all. Pacer keeps itself up to date automatically: when a new version
ships, it offers to install it for you — no re-downloading, no reinstalling.

You'll need macOS 15 (Sequoia) or newer,…
