Stay on Budget
Monitor your Claude Code usage in real time. Get push notifications before you hit your spending limits — across macOS, iOS, and watchOS.
Everything you need to stay on budget
Real-time monitoring
FSEvents-based file watcher reads Claude Code's local session data instantly. Zero polling delay, zero cloud dependency.
Push notifications
Set daily cost, token, or session thresholds. Get an APNs push to your iPhone or Apple Watch the moment you exceed them.
Multi-platform
macOS menu bar widget, iOS dashboard, and watchOS complications — stay informed on every device you own.
Privacy-first
Usage data never leaves your Mac. The cloud relay only forwards push notification triggers — nothing else is stored.

Why HowlAlert
Zero Polling Delay
Native FSEvents integration means your usage data updates the instant Claude Code writes it. No intervals, no lag.
Privacy by Design
All processing happens on-device. The only data that leaves your Mac is the push notification trigger — no usage details, no telemetry.
Every Device
macOS menu bar, iOS app, and watchOS complications. One threshold config, alerts everywhere.
