LanfinchEvery device on your Wi‑Fi.
Lanfinch finds everything on your network in seconds: what it is, who made it, which ports are open. With SSH, ping and port scan built in. It all stays on your phone.
Scanning is free. 3 days of everything, then one purchase.
Know what's on your network.
Not just IP addresses. Lanfinch asks every device who it is, and remembers what changed.
Real names
From Bonjour, NetBIOS and the devices' own web pages, plus the maker from the MAC address.
What changed
New devices, devices that went offline and devices that moved to another IP since your last scan.
Open ports
Every device's open ports and services at a glance, and a port scan whenever you want more.
Smart home ready
Filters for ESPHome, Home Assistant, Shelly, WLED, MQTT, cameras and Raspberry Pi.
Security checks
Warnings for Telnet, FTP, unencrypted MQTT, admin pages without HTTPS and duplicate IPs.
Export
Your device list as CSV, YAML or a Home Assistant known_devices file.
Tap a device. Get to work.
Each device shows only the tools it actually supports.
- SSH terminal with keys made on your phone, and an optional Face ID lock for saved logins.
- Ping graph and port scan for when something doesn't answer.
- Web interface of routers, printers and smart devices, one tap away.
- ESPHome logs, MQTT messages, and Shelly plugs or WLED lights to switch.
- Notes, your own names and a timeline per device.
A real terminal in your pocket.
Paste, Ctrl and arrow keys included. Host keys are checked, logins stay in the Keychain or Keystore.
No subscription. No account. All future updates included.
Your network stays yours.
Lanfinch talks to the devices on your network, and to nothing else.
