Private Eye
Private Eye is a free Mac network monitor that shows which apps are making incoming and outgoing internet connections in real time.
What is Private Eye?
Private Eye is a native Mac network monitoring app that helps users see which applications are connecting to the internet. It is designed for people who want a simple, lightweight way to watch live network activity without using a more complex firewall or packet analysis tool. The app shows connections as they happen and lets you narrow the view by app or by traffic direction, which is useful when troubleshooting unexpected network activity or checking what software is communicating online. Private Eye is offered by Radiosilenceapp as a standalone monitor rather than a blocking tool, so its role is visibility rather than control. It is especially helpful for privacy-conscious users, support troubleshooting, and quick checks of background network behavior on older versions of macOS.
Key features
- Monitor network connections in real time as apps communicate online
- Filter activity by individual app to focus on a specific program
- View incoming and outgoing connections separately
- Use a lightweight interface for quick troubleshooting and privacy checks

Safety overview
Status: Mostly safe
Private Eye is a legitimate network monitoring utility for Mac. Because it watches connection activity across apps, users should expect network visibility that is normal for this type of tool. It is a monitor only, not a blocker, so it helps you observe traffic rather than change system behavior. If you use it, download it from the official site and keep in mind that the product is no longer actively maintained, which can matter for compatibility on newer macOS versions.
Recommendation: Keep Private Eye if you use it to inspect network activity or troubleshoot which apps are connecting online. If you do not use this kind of monitoring, it is optional and can be removed without affecting normal macOS operation, though you may lose its connection-viewing capability.
