Sniffnet
Sniffnet is a desktop network monitoring app that helps users inspect Internet traffic, view connection details, and spot bandwidth activity in real time.
What is Sniffnet?
Sniffnet is a network monitoring app for macOS, Windows, and Linux that helps users inspect Internet traffic through a graphical desktop interface. It is designed for people who want an easier way to watch live network activity without working entirely from the command line. Users can choose a network adapter, apply traffic filters, review real-time charts, and inspect individual connections as traffic flows through the system. The app also shows details such as remote host locations, domain names, ASNs, protocols, and local network connections, which can help with troubleshooting, learning, and general network awareness. Sniffnet supports importing and exporting PCAP capture files, and recent versions can identify which programs are using network bandwidth. Published by GyulyVGC, it is a utility for users who want a focused, visual way to monitor network behavior on their Mac.

Safety overview
Status: Mostly safe
Sniffnet is legitimate network monitoring software, but its purpose involves inspecting network activity, so some access related to packet capture or network interfaces is normal. Because it can reveal connection details such as hosts, domains, and traffic patterns, treat the information it shows as sensitive if you share screenshots or reports. Keep the app updated, use it only on networks you are authorized to inspect, and review any exported capture files before storing or sending them to others.
Recommendation: Keep Sniffnet if you actively monitor, troubleshoot, or study network traffic on your Mac. If you installed it for a one-time task and no longer use it, removing it is usually fine and will only affect your ability to view and analyze traffic with this app.
