The network engineering platform for AI agents.
Build, break, and troubleshoot real network architectures with a distributed lab platform designed for modern engineers.
One canvas, live AI agents, one event stream - the whole network lifecycle in a single platform.
Run the gear you actually ship.
QEMU/KVM under the hood means real vendor images - the same IOS-XE, Junos, EOS and PAN-OS you run in production. 140+ device kinds across 65+ vendors, with automatic image fixes on every upload.
Not another lab.
The next generation of one.
This isn't a knock on the tools that got you this far - it's what a network lab looks like when it's rebuilt from scratch in 2026.
SSH in to fix permissions
Upload an image, SSH into the host, run a wrapper script by hand, hope the folder name matches - or it silently doesn't appear.
Drop an image, walk away
Conversion, permissions and boot-testing happen automatically, driven entirely from the browser. Nothing to SSH into.
One box, one ceiling
A single server is the whole lab. Outgrow it and the only answer is a bigger, more expensive machine.
Distributed labs
Stitch multiple machines into one topology over an encrypted VXLAN fabric (currently in beta) - scale out instead of up.
Manual troubleshooting
Every BGP session, every VNI, every route checked by hand, one CLI at a time, across every device in the topology.
Troubleshooting via your AI agent
Connect any AI agent to the lab over MCP and have it walk the topology, pull live config and CLI output, and reason about what's wrong.
We'd rather you tried it than believed us.
Every feature on this page is real and live today - not a mockup, not a roadmap slide. Go check for yourself, starting on the free tier - no card, no sales call.
Connect any AI agent.
It already knows your lab.
netplex. ships a real MCP server - the same protocol Claude, Cursor and other AI agents use to act on live systems, not just chat about them. Point one at a running lab and it can see the topology, read live configs, and run commands.
- 24 MCP tools - list, build, wire and power labs, read topology, run CLI commands
- Works with any MCP-compatible agent - bring your own, no lock-in
Purpose-built EVPN/BGP diagnostic tooling is on the roadmap - today's agents reason over the same live topology, config and CLI data a human engineer would check by hand.
> Why is traffic failing between Leaf01 and Leaf02?
checking underlay reachability... OSPF up, VTEPs reachable
checking VXLAN tunnel state... tunnel established, VNI 10100 active
checking VLAN-to-VNI mapping on Leaf02... not found
✓ Root cause: missing VLAN-to-VNI mapping on Leaf02.
Illustrative - what a connected AI agent can do with netplex's live MCP tools today, not a built-in diagnostic button.
Half your lab at home.
Half in the cloud.
One canvas. One click.
Our flagship differentiator - an orchestrator schedules your topology across as many worker hosts as you own, and stitches their virtual switches together with encrypted VXLAN tunnels, transparent to the emulated devices. Your BGP adjacency doesn't know - or care - which machine the iron is on.
Distributed multi-chassis VXLAN is on the roadmap (in beta) - single-host emulation and automation ship today.
- One orchestrator schedules placement across every worker by free RAM
- Outgrow a single box without buying a bigger server
- Each host gets a colour; nodes glow to show where they live
The link doesn't care which worker a node lives on.
Simulate real network conditions.
Not just up or down.
Real networks degrade before they fail outright. netplex. lets you reproduce that on any link, live.
Latency & jitter
Add real delay and jitter to any link with tc/netem, and watch routing protocols react the way they would in production.
Packet loss
Drop a precise percentage of traffic on a link to reproduce a flaky WAN circuit or a failing transceiver.
QoS & bandwidth
Shape bandwidth per link to model congestion and prioritisation - see which traffic survives when the pipe gets small.
Live link colour & flow
Links colour and animate with real traffic on the canvas, so a failing or degraded path is visible before you open a single CLI.
PowerPoint meets
a live network topology.
Present a design, demonstrate a failure, and explain the fix - on the real, running topology, not a static slide. Built for consultants, trainers and architects walking a room through a design.
- Laser pointer, pen, highlighter, arrow, box, oval, spotlight and eraser tools
- Full undo/redo - annotate live without fear of a mistake
A live, running topology - presented, not a screenshot.
You don't have to pay.
But here's what you can't buy elsewhere.
netplex. Associate is free forever - a React canvas, live terminal, packet capture and a full API included, not stripped out and sold back to you.
- Modern React canvas + live terminal
- Per-node snapshots + git auto-backup
- Full REST + WebSocket API, scoped keys, CLI
- Live packet capture (Wireshark) on any link
- tc/netem QoS shaping on every link
- Licence runs anywhere - no MAC lock
Professional runs anywhere and adds snapshots, fault injection and app nodes; Architect adds presentation mode and the full automation toolbox. Coming from EVE-NG, GNS3 or Containerlab? See exactly how we compare →

Emulate
A circuit-board canvas you'll actually want to look at. Drag nodes, draw links in four styles, capture packets live on any wire, and watch real traffic move - not invented Gbps numbers.
Automate
Everything the UI does is an API call. API keys, a CLI, CI-ready lab tests and a full tc/netem QoS suite ship today; the Terraform provider and Ansible collection are in beta.
Ship
Labs become code you keep in your own Git, with automatic backup on every stop. Pipeline a fresh topology on every commit, verify, and catch breakage before production.
Your laptop, your rack - or your cloud.
One installer runs netplex on AWS, Azure, Google Cloud and Oracle Cloud - with an honest per-cloud guide to running heavy vendor VM images at full speed.

Bring your existing labs.
Your EVE-NG and GNS3 topologies aren't a reason to stay - they're a one-click import. Startup configs, canvas positions and node wiring carry over, so switching costs you minutes, not a rebuild.
Built by network engineers,
for network engineers.
netplex. is designed and built in Australia by people who lived inside EVE-NG, PNETLAB and GNS3 for years - and got tired of SSH-ing in to run fixpermissions. Every decision is made by engineers who use it daily, not a marketing department.
Stop building yesterday's labs.
Start engineering tomorrow's networks.
Import your existing lab, start on the free Associate tier, and never run fixpermissions again.
