Free Process-Traffic Monitor — Lightweight Tool for Windows & macOS

Free Process-Traffic Monitor is a small utility that shows per-process network and CPU usage in real time for Windows and macOS. It helps identify which applications are using bandwidth or CPU, diagnose slowdowns, and spot unwanted background activity.

Key features

• Real-time per-process network bandwidth (upload/download) and CPU usage.
• Lightweight footprint — low memory and CPU overhead.
• Simple system tray / menu bar access with quick summary and detailed view.
• Process filtering and sorting (by bandwidth, CPU, name).
• Traffic history graph for short-term trends.
• Alerts/notifications for processes exceeding configurable thresholds.
• Export logs or snapshots for troubleshooting.
• Cross-platform builds for Windows and macOS (native UI elements).

Typical use cases

• Find apps causing internet slowdowns or data spikes.
• Monitor background sync, updates, or cloud backups.
• Detect unexpected outbound connections from unknown processes.
• Measure bandwidth usage per app when on limited data plans.
• Troubleshoot high CPU correlated with network activity.

Security & privacy notes

• The tool needs permissions to access per-process network and system metrics; on macOS this may require granting network monitoring or full-disk/accessibility permissions depending on implementation.
• Prefer official releases from the developer or an open-source repository to avoid tampered binaries.

Alternatives (examples)

• Windows: Resource Monitor, TCPView, GlassWire.
• macOS: Activity Monitor (with limited per-process network info), Little Snitch (commercial), LuLu (network firewall/monitor).
