About
A concurrent network scanner written in Go that discovers live hosts via TCP, ICMP, ARP, and mDNS, then scans open ports, resolves vendors from MAC/OUI data, and heuristically fingerprints operating systems. It ships as a single binary with both a Bubbletea-based TUI and a plain-text CLI mode for scripting.
What it can do
Discover live hosts on a network using TCP, ICMP, ARP, and mDNS probes
Network subnet range → List of live hosts
Scan discovered hosts for open ports
Host IP address → List of open ports
Resolve device vendor from MAC address using OUI data
MAC address → Vendor name
Heuristically fingerprint device operating system
Scan results → Guessed OS type
Why it made the leaderboard
Gives developers a fast, dependency-light way to discover and fingerprint hosts on their network from the terminal, without pulling in nmap or a GUI scanner.
