Free interactive Nmap command builder. Point-and-click to generate professional Nmap scan commands — host discovery, port scans, OS & version detection, NSE scripts, timing and evasion. Learn every flag with examples.
The Nmap Command Workbench is a free, interactive tool that lets you build professional Nmap (Network Mapper) scan commands with point-and-click options — no memorising flags. Pick your target, scan type, ports, timing and NSE scripts, and the exact command is generated live, ready to copy into your terminal. It is built by Cyber Defence, an ethical-hacking and cyber-security training institute in Hisar, Haryana, for students, SOC analysts and penetration testers.
nmap 192.168.1.1 — a basic scan of the 1,000 most common ports on a host.nmap -sS -p- 192.168.1.1 — a stealth SYN scan of all 65,535 ports.nmap -sV -sC 192.168.1.1 — detect service versions and run default NSE scripts.nmap -O 192.168.1.1 — attempt operating-system detection.nmap -A -T4 192.168.1.1 — aggressive scan: OS + version + scripts + traceroute.nmap -sn 192.168.1.0/24 — ping sweep to find live hosts on a subnet.nmap -p 80,443 --script http-title 192.168.1.1 — targeted port scan with an NSE script.-sV), OS detection (-O), timing (-T4) or NSE scripts.Nmap is the industry-standard open-source tool for network discovery and security auditing — finding live hosts, open ports, running services and their versions, and potential vulnerabilities.
Yes. The Nmap Command Builder is completely free to use online, with no login required.
Scanning networks and systems you own or have explicit written permission to test is legal. Scanning third-party systems without authorisation may be illegal. Always get permission first.
A ping sweep (nmap -sn) is fastest for host discovery. For port scans, higher timing
templates such as -T4 speed things up on reliable networks, at the cost of stealth.
