Meet 3D Live: walk inside the network you built

NetForge · posted Oct 9, 2026 · 3 views

Hi everyone, the NetForge-AI team here.

Meet 3D Live: the network you build in the lab, turned into a 3D world you can walk through.

Wire a topology on the 2D canvas, press 3D Live, and a little engineer stands among your switches, routers, PCs and servers, with every cable you connected. Send a ping and watch it travel. Then step inside a device. A router shows each stage of handling the packet, from the port it arrived on to the new Ethernet header it writes, with the real addresses, the device's own tables and the show command that proves each step.

There are guided fault-finding missions too, and anything you build in 3D is saved back to your lab: the 2D canvas and 3D Live are one network.

3D Live is free on every plan and opens without an account. Try it at netforge-ai.com/lab/world
