System telemetry for Mac fleets
Collect CPU, memory, GPU, disk, and network metrics from every Mac endpoint. Fully manageable via MDM and CLI. Analyze locally with the built-in dashboard, or optionally ship to Splunk.
Built with native Swift & SwiftUI — lightweight, fast, and privacy-focused
Always accessible
Pulse continuously collects metrics in the background at configurable intervals. The menu bar widget gives you instant access to real-time data, top processes, and collection status.
- Continuous background collection over hours, days, or weeks
- Live CPU and memory pressure
- Top 5 resource consumers
- Scheduled upload to Splunk (optional)
- Find and pin specific processes
Deep analytics
The built-in dashboard provides rich visualizations without requiring Splunk. Interactive charts, process overlays, and historical data at your fingertips.
- Interactive time-series charts
- CPU, memory, thermal, and pressure graphs
- Process attribution on hover
- Spike vs. sustained usage analysis for top processes
- Configurable time ranges

Built for enterprise
Everything IT teams need to deploy and manage at scale
MDM Ready
Full managed preferences support. Deploy via Jamf, Mosyle, Kandji, or any MDM solution. Lock settings from user modification.
Splunk HEC (Optional)
Stream all metrics to Splunk via HTTP Event Collector. Batch uploads with automatic retry and configurable intervals. No Universal Forwarder needed.
CLI Control
Full command-line interface for scripted control. Start, stop, configure from Terminal or MDM scripts with automatic user context elevation.
Local Storage
JSONL format with configurable retention. Works completely offline. Analyze historical data without network connectivity.
Alerting
Get notified when CPU or memory pressure exceeds thresholds. Pin specific processes for detailed tracking. Configurable thresholds, sustained duration, and cooldown periods.
Headless Mode
Run without the menu bar icon for silent background operation. Users never see or interact with the app while metrics are collected.
Requirements
- macOS 14.0 (Sonoma) or later
- For Splunk (optional): Enterprise or Cloud with HEC enabled
