Can iNTM show network traffic by app?

Yes. iNTM is designed to connect traffic usage with applications so you can identify which Mac apps are using bandwidth.

Can it help find unusual background traffic?

Yes. Real-time speed, per-app usage, connection details, and history make it easier to investigate unexpected traffic spikes.

Does iNTM replace a firewall?

iNTM includes local app firewall controls, so you can monitor traffic and create rules for apps, domains, IPs, and ports.

macOS Network Traffic Monitor for Per-App Bandwidth - iNTM

Monitor macOS network traffic in real time, analyze per-app bandwidth usage, review traffic history, and control connections with local firewall rules.

Monitor macOS network traffic in real time, analyze per-app bandwidth usage, review traffic history, and control connections with local firewall rules.
See which apps are using your network, how much bandwidth they consume, where connections go, and which requests deserve a local firewall rule.
What you can monitor
Built for real Mac network visibility
Activity Monitor can show broad network numbers. iNTM goes deeper by connecting traffic usage, applications, remote endpoints, history, and control in one native macOS workflow.
Real-time traffic speed
Track upload and download speed as it changes, including quick status bar visibility for day-to-day monitoring.
Per-app bandwidth usage
Identify which Mac apps consume bandwidth and separate normal background traffic from unusual spikes.
Traffic history review
Review historical network usage by app and time period, then use trends to understand recurring bandwidth drains.
Local app firewall control
Create rules for apps, domains, IPs, and ports when monitoring reveals a connection you do not want to allow.
Workflow
From traffic spike to clear action
A useful macOS network traffic monitor should help you move from noticing activity to understanding and controlling it.
Watch real-time network activity
Use live speed and connection views to spot unexpected upload or download activity.
Find the app behind the traffic
Group usage by application so a vague network spike becomes a specific process you can inspect.
Review remote endpoints
Check domains, IP addresses, ports, protocols, and connection timing before deciding whether traffic is expected.
Apply a local rule when needed
Block or restrict unwanted traffic with app-level firewall rules that run locally on your Mac.
Comparison
Why not just use Activity Monitor?
Activity Monitor is useful for a quick system snapshot. iNTM is designed for people who need ongoing network traffic monitoring, per-app investigation, and connection control.
Live speed
Basic network throughput at system level.
Real-time traffic monitoring with app-focused context and status bar visibility.
Per-app analysis
Limited detail for investigating app bandwidth patterns.
Per-app usage, historical trends, and connection details in one workflow.
Connection control
Observation only.
Local firewall rules for apps, domains, IPs, and ports.
Privacy posture
Local system utility.
Traffic metadata and firewall rules are processed locally; packet content is not uploaded.
