LanSheet: Network Scanner

One scan shows every device on your network with its name, model and maker. Name them yourself, and next time you can see at a glance what has appeared since.

LanSheet shows you what is on your network. Run a scan, and every reachable device appears with its name, model and maker, instead of a list of bare numbers.

MORE THAN A SNAPSHOT Most scanners show you what is answering right now. LanSheet keeps a sheet on your network. You give your devices your own names, symbols and notes, and they stay put even when an address changes. The next scan shows you at a glance what has appeared since.

IDENTIFY DEVICES • Names, models and makers from Bonjour, DNS, NetBIOS, UPnP, SMB and the services the devices offer • Every detail says where it came from. Anything merely inferred looks like it. • Open ports and announced services in plain words, from AirPlay to HomeKit • TLS certificates with their issuer and expiry, and the software answering on a port • A file server's shares, as far as it names them without a login • NDI® sources on your network, with no extra purchase and no subscription • Devices that answer no ping at all

KEEP TRACK • Your own names, symbols, rooms and notes for each device • Several networks side by side, recognised by the devices on them: home, office, holiday flat • History per device: first seen, last seen, address changes • New, back and missing since the last run, at a glance • A notification when an unknown device turns up • A widget with the device count and whatever has appeared since • Export as CSV or Markdown

TOOLS • Ping with history, loss rate and jitter • Traceroute • Port scan across common services or a port list of your own • A bandwidth test between two devices running LanSheet • Wake on LAN • Open a device's web interface, SSH or file share directly • Your own Mac's interfaces, DNS servers and routing table • Shortcuts for scanning, unknown devices and waking a device

ON ALL YOUR DEVICES • Mac, iPhone and iPad • iCloud sync for your names and notes

HONEST ABOUT THE LIMITS LanSheet finds whatever answers a probe. A device that answers nothing, announces nothing and carries no name stays invisible. The app says so, rather than claiming a completeness it cannot deliver. And not every feature exists on every system: whatever is missing on the iPhone is marked as such in the app.

YOUR NETWORK STAYS YOURS • No account, no sign-in • No ads, no analytics, no data collection • Your names and notes travel to your other devices through your private iCloud, and nothing else leaves the machine

ONE PRICE, EVERY PLATFORM LanSheet is a single purchase covering Mac, iPhone and iPad together. No subscription, no extra unlocks, every feature included from the start.
