UDPz is an open-source UDP service scanner written in Go. It probes dozens of protocols across IPs, hostnames, CIDR ranges or target files without requiring root access, supports SOCKS5 tunnelling, and produces structured logs. It is aimed at network administrators and security professionals who find conventional tools too slow for UDP scanning.
