🔦 Netfox 0.16.0 — the ports your network scan could never see

🔦 Netfox 0.16.0 is out — and this one finds what a network scan structurally can't.

Here's the blind spot. Netfox checks every device by connecting to it across your network. Perfect for a printer, a NAS, a phone. Wrong for the Mac you're sitting at 👀

A dev server on 127.0.0.1:3000 genuinely refuses connections from anywhere else — so the check says "closed". Accurate, and completely useless. The most interesting services on the machine you care most about are exactly the ones a network probe can never see.

🆕 Local Services — a new tab on This Mac that doesn't probe anything. It asks the system directly, then splits the answer in two:

The Local Services tab: this Mac's listening ports, split into the ones only it can reach and the ones the network can

🟠 Only on this Mac — bound to loopback. Nothing else on your network can reach them. Dev servers, database engines, helper tools.

🌐 Reachable from the network — anything on your Wi-Fi can connect. Usually intended. Occasionally a surprise.

✨ And names instead of numbers. 3000 tells you nothing. shop.local:3000 tells you which project it is. If your hosts file has names pointing at a listener, they show up right beside the port — which is the moment a list of numbers becomes a list of the side projects you forgot were still running.

🔎 For every other device, the Ports tab still works the way it always has — probed across the network, grouped by category. Local Services is the one place that couldn't work that way:

The Ports tab on a network device, grouped by category

🐛 Also fixed: a closed port now says closed. A port that actively refuses a connection was being reported as filtered — and those mean different things. Nothing listening, versus something in the way. It was a wrong answer on every scan, and a slow one: a refusal is an instant answer that was being waited out to the full timeout.

🔒 Demo Mode covers the new list too — process names, their numbers and any names of your own vanish with one keystroke, so a screenshot of what's running never gives away what you have installed.
