Lanfinch: Network Scanner

Every device on your network, with names, makers and open ports. SSH, ping and port scan built in. Local, with no account and no subscription.

Lanfinch shows every device on your network in seconds: what it is, who made it, which ports are open and what it announces. Everything stays on your iPhone or iPad: no account, no cloud, no tracking.

SCAN • Finds the devices on your whole home network, also on larger mesh networks • Names from the devices themselves (Bonjour, NetBIOS, their own web pages) and the maker from the MAC address • See what's new, what's gone and what moved to another IP address since your last scan • Warns you when two devices use the same IP address

FOR YOUR SMART HOME • Smart filters: ESPHome, Home Assistant, Shelly, WLED, MQTT, SSH, web interfaces, cameras and Raspberry Pi • Your own filter for any port • ESPHome details and live logs; switch Shelly plugs and WLED lights

TOOLS • SSH terminal, with keys made on your iPhone and an optional Face ID lock for saved logins • Ping graph and port scan • Open a device's web page and listen in on MQTT messages • Security checks for Telnet, FTP and admin pages without HTTPS

MAKE IT YOURS • Rename devices, choose their type, add a note • Export as CSV, YAML or a Home Assistant file • A timeline per device: online, offline, new IP address • On iPad, the list and the details side by side

TRY IT FREE Scanning is free. Try all details and tools free for 3 days, then unlock them with one purchase: no subscription, all future updates included. Without it, the list shows six devices.
