Pacer dashboard — today's cost, 5-hour and 7-day rate-limit pacing, live burn rate, and a projected end-of-day total

How Pacer compares

There are good ways to watch Claude Code usage — the built-in /usage, the ccusage CLI, and menu-bar apps like Claude God and ccseva. Pacer leans into pacing — your windows against an ideal-burn line, "will I run out before the reset?" — stays native and quiet-by-default, and signs & notarizes its own auto-updates. The full, honest side-by-side lives in the README.

Your data stays on your Mac

Pacer is local-first. It reads only the files Claude Code already writes to your own machine, and sends nothing about your usage anywhere — no account, no telemetry, no cloud.
