The original
Angry IP Scanner
A fast, friendly IP and port scanner that needs no installation and runs on Windows, Mac and Linux.
Replacements
Listings that take over the same core job as Angry IP Scanner.
Nmap
The network mapper: find out which hosts are up, which ports are open and what is listening on them.
Nmap goes much deeper with service versions, OS fingerprinting and scripts, but uses a custom non-OSI licence instead of GPL-2.0 and has a steeper learning curve.
Advanced IP Scanner
Scans a home or office network and lists every device with its name, MAC address and shared folders.
Advanced IP Scanner shows hostnames, MAC addresses and shared folders and opens RDP sessions, but it is closed source, Windows only and last released in 2023.
Fing
Network scanner that identifies the devices on your network.
Fing adds more accurate device identification, new-device alerts and mobile apps, but it is closed source and advanced features require a paid subscription.
RustScan
Discover open ports with a configurable scanner written in Rust.
RustScan is a GPL-3.0 command-line port scanner written in Rust that needs no Java runtime and can hand results to follow-up scripts.
Naabu
Discover listening network ports with a command-line scanner.
Naabu is an MIT-licensed command-line port scanner with several scan methods and optional Nmap integration, with no graphical interface.
masscan
Scan large sets of IP addresses for open ports.
masscan scans very large address ranges at high packet rates from the command line under AGPL-3.0, but it has no GUI and no Windows build.
LAN Orangutan
Lightweight network scanner with persistent device labels.
LAN Orangutan keeps persistent device labels between scans and adds Tailscale integration, but it is a young project with a smaller feature set.
Zenmap
The official cross-platform graphical interface for the Nmap network scanner.
Zenmap puts Nmap's detailed scanning behind a cross-platform graphical interface with saved profiles and scan comparison, but it depends on a separate Nmap installation.
Also worth comparing
These listings name Angry IP Scanner as their own alternative, so the relationship runs both ways.
Advanced Port Scanner
A free Windows port scanner that finds open ports and identifies the programs running on them.
Angry IP Scanner is open source under GPL-2.0 and runs on Windows, macOS and Linux, but finds hosts and open ports without identifying program versions.
arp-scan
Command-line tool that discovers and fingerprints hosts on a local network using ARP.
Angry IP Scanner offers a graphical, cross-platform scanner under GPL-2.0 that can scan internet ranges too, though it needs a Java runtime and finds only hosts and ports.
fping
A command-line ping tool that sends ICMP echo probes to many hosts at once.
Angry IP Scanner adds a graphical interface on Windows, macOS and Linux for sweeping address ranges, and needs a Java runtime for the bare jar.
IP Scanner
A network scanner for Mac and iPhone that identifies every device on the local network.
Angry IP Scanner is open source under GPL-2.0 and adds port scanning on Windows, macOS and Linux, though its macOS build lacks a maintainer.
LanScan

Angry IP Scanner is free and open source under GPL-2.0, adds port scanning on several platforms, though its macOS build lacks a maintainer.
MyLanViewer Network/IP Scanner
A Windows IP scanner that lists computers, MAC addresses and shared folders on a local network.
Angry IP Scanner is free and open source under GPL-2.0, runs on Windows, macOS and Linux, but has no alerts for new devices.
netdiscover
An ARP scanner that finds hosts on a local network by active or passive discovery.
Angry IP Scanner is a GPL-2.0 graphical scanner for Windows, macOS and Linux that can scan internet ranges as well, but lacks passive ARP discovery.
SoftPerfect Network Scanner
A multi-threaded IPv4 and IPv6 scanner that finds network devices, open ports and shared folders.
