  • masscan

    Scan large sets of IP addresses for open ports.

    A fast, friendly IP and port scanner that needs no installation and runs on Windows, Mac and Linux.

    FreeOpen sourceWindowsmacOSLinux

    Angry IP Scanner adds a graphical interface and needs no installation on Windows, macOS and Linux, focusing on host discovery and open ports with a Java runtime.

  • ZMap

    A fast single-packet network scanner designed for surveys across very large address ranges.

    FreeProprietaryLinuxCommand line

    ZMap is a single-packet scanner for very large address ranges with 10 gigabit tuning, Linux only, finding open ports without detailed service information.

    Zenmap is the graphical interface for Nmap with saved profiles and scan comparison, requiring Nmap to be installed separately.

Also worth comparing

These listings name RustScan as their own alternative, so the relationship runs both ways.

    FreeProprietaryWindows

    RustScan is an open-source GPL-3.0 command-line port scanner for all major platforms that focuses on open ports rather than listing device names and shares.
