Simulate Real Networks in Your Browser
Design, build, and test network topologies without physical hardware. Watch packets travel in real-time, configure routing, and understand network behavior — all inside your browser.
Everything You Need to Simulate Networks
A full-featured simulation environment built for students, engineers, and IT professionals.
Drag & Drop Canvas
Place routers, switches, servers and PCs onto a free-form canvas intuitively. Connect devices with a single click and rearrange at any time.
Real-time Packet Animation
Watch data packets travel through your network live. Visualize routing paths, ARP requests, ICMP pings, and broadcast storms as they happen.
10+ Device Types
Simulate routers, managed switches, hubs, PCs, servers, firewalls, and wireless access points — all with configurable IP addresses.
Topology Templates
Jump-start your lab with pre-built topologies: Star, Ring, Mesh, Bus, and Tree networks. Or design your own from a blank canvas.
Live Event Log
Monitor every network event in real-time — ARP resolution, ICMP pings, routing table updates, and packet forwarding — in a scrollable console.
Zero Setup Required
Open your browser and start simulating instantly. No downloads, no plugins, no account required. Works on Chrome, Firefox, Safari, and Edge.
How It Works
Get your first simulation running in under 60 seconds.
Add Devices
Pick from the device library and drag routers, switches, servers, and PCs onto the canvas.
Connect & Configure
Draw cables between devices, assign IP addresses, and configure routing protocols with a simple interface.
Simulate & Analyze
Send pings, run traceroutes, and watch packets animate through your topology in real-time.
