Group by App
Port Master-style grouped connections view. All connections from chrome.exe, discord.exe, or steam.exe collapsed under one expandable header.
New
Firewall Manager
View, add, toggle, and delete Windows Firewall rules. Block specific apps, IPs, or ports — inbound or outbound — with a clean UI.
Bandwidth Monitor
Real-time upload and download charts per network adapter. Animated sparklines track your throughput history over time.

Threat Analysis
Automatically flags connections using suspicious ports like 4444, 1337, 31337. Highlights unusual processes and lets you block with one click.
Diagnostics
Run Ping, Traceroute, DNS Lookup, Whois, ARP Table, and Route Table directly in the app. Inline terminal-style output, no cmd needed.
ARP + Route
Network Map
Animated radar scans your local subnet via ARP ping. Discovers all live devices with their IP and MAC addresses in real time.
