Overview
Crustat lives in your menu bar and gives you a glance-able view of your Claude Code usage — token usage, rate limits, recent activity, and Anthropic’s status.
Crustat has two independent halves. The local stats always work; the live limits need a Claude subscription login.
| What you see | Where it comes from | Needs Claude login? |
|---|---|---|
| Token usage — today / this week, by model, by project, and the 7-day trend | Read locally from your Claude Code session logs | No — always works |
| Service status — Anthropic uptime | status.anthropic.com | No |
| Rate limits — your usage-% toward your plan limits, and the menu-bar badge | Anthropic's account API, using your Claude Code login | Yes |
So even without signing in, Crustat is a useful local usage dashboard — the limits section is the part that needs your Claude login. See Signing in for how that works.
Crustat runs entirely on your Mac and sends none of your data anywhere of ours. See the Privacy Policy for details.
