Meet LAN Orangutan: Know Every Device on Your Network

Few people can list every device on their own network. Phones, laptops, smart TVs, printers, cameras and the odd gadget a guest left behind all share it. LAN Orangutan answers the question "what is on my network?" and keeps answering it.

What it does

• Finds every device on your networks using nmap, with live progress you can cancel.
• Lets you label, group and add notes to devices, with your own group names.
• Saves snapshots of your network so you can compare them later and see what changed.
• Tells you when something new appears or a device you expect goes missing.
• Connects to Tailscale from inside the app, so your tailnet devices appear alongside your local ones.
• Exports a shareable HTML report, and backs up and restores everything.

It is a single program with no dependencies, protected by a password you set, with a web dashboard in light and dark mode and a full command line with JSON output.

Install it

Why the name

"Orangutan" is Malay for "person of the forest". LAN Orangutan is the person of your network: it watches everything that moves, remembers every device it has ever met and bothers no one. Orangutans are also the most solitary of the great apes: no troop, no cloud, no phoning home.

What is next

The next releases focus on features the community has asked for.
