Replacements
Listings that take over the same core job as LAN Orangutan.
Fing
Network scanner that identifies the devices on your network.
Fing identifies devices accurately using its cloud database and alerts on new devices, but it is closed source and history and advanced features need a paid subscription.
Angry IP Scanner
A fast, friendly IP and port scanner that needs no installation and runs on Windows, Mac and Linux.
Angry IP Scanner is a GPL-licensed portable scanner for Windows, macOS and Linux with exports and a command line, but it does not keep persistent device labels.
Advanced IP Scanner
Scans a home or office network and lists every device with its name, MAC address and shared folders.
Advanced IP Scanner is a free, closed-source Windows-only scanner that lists hostnames, MAC addresses and shared folders, but it has not been released since 2023 and triggers security alerts.
Nmap
The network mapper: find out which hosts are up, which ports are open and what is listening on them.
Nmap adds service and version detection, OS fingerprinting and scripting on all major platforms, but it is a heavier tool under a custom licence that is not OSI-approved.
NetAlertX
A self-hosted network scanner that discovers devices on your networks and reports changes.
NetAlertX offers continuous self-hosted device discovery with alerts through Docker, but needs an always-on server and is not open source.
WatchYourLAN
Lightweight self-hosted network IP scanner with a web interface and alerts for new hosts.
WatchYourLAN adds new-host alerts, online history and Prometheus or InfluxDB export via Docker, covering only the local network without a Tailscale integration.
SoftPerfect Network Scanner
A multi-threaded IPv4 and IPv6 scanner that finds network devices, open ports and shared folders.
SoftPerfect Network Scanner queries devices over WMI, SNMP and SSH on Windows, macOS and Linux, but requires a paid licence and is closed source.

LanScan
