What makes NetPilot different for Cisco virtual labs

CML, GNS3, and EVE-NG all run real Cisco IOS. NetPilot combines cloud-native + AI-designed + multi-vendor in one shot — different bet, different use case.

Cloud-native Cisco lab

Browser only. Real Cisco IOL in the cloud via BYOI. No VM, no 32 GB RAM server.

The alternative

CML needs a VM + nested virtualization. GNS3 needs 32 GB RAM. EVE-NG needs a dedicated 16 GB+ server. All self-hosted.

AI-generated Cisco configs

Describe any Cisco topology in plain English. AI writes the IOS config for every router and switch.

The alternative

CML / GNS3 / EVE-NG: manual drag-and-drop GUI + hundreds of lines of IOS CLI typed by hand per device.

Multi-vendor alongside Cisco

Cisco IOL + Juniper cRPD + Arista cEOS + Nokia SR Linux + Palo Alto in one topology (commercial NOSes via BYOI) — AI handles vendor syntax.

The alternative

CML is Cisco-only. GNS3 / EVE-NG support multi-vendor but every image is BYOI with per-vendor CLI expertise needed.

Minutes vs hours per lab

Minutes from prompt to working Cisco lab. No node limit on typical labs.

The alternative

CML: 2-4 hrs VM setup + 5-node cap on free. GNS3: 4-8 hrs. EVE-NG: 1-2 days server + images.

See It in Action

Describe a Cisco lab, deploy to the cloud, SSH into real devices — all from your browser.

Why Cloud-Hosted Cisco Labs?

Traditional virtual labs need VMs, servers, and hours of setup. Cloud labs eliminate all of that.

No Server, No VM

CML needs a VM. GNS3 needs 32GB RAM. EVE-NG needs a dedicated server. NetPilot runs in the cloud — open your browser and go.

Real Cisco IOL CLIs

SSH into real Cisco IOL routers and L2/L3 switches (bring your own Cisco image). Run show commands, configure OSPF, troubleshoot ACLs — real IOS, not a simulation.

AI Builds Everything

Describe your lab in plain English. AI generates the topology, assigns IPs, writes Cisco IOS configs, and deploys — in minutes.

What You Can Build

From CCNA practice to enterprise topologies — describe any Cisco lab and deploy with real CLIs.

OSPF & EIGRP Labs
BGP Configurations
VLAN & Trunking
ACLs & NAT
MPLS Networks
STP / RSTP Labs
DHCP & DNS
CCNA / CCNP Prep
Inter-VLAN Routing
EtherChannel / LACP
Port Security
Multi-Vendor Labs

How It Works

Open your browser, describe the Cisco lab, and SSH into real IOS CLIs — in minutes.

1

Open your browser — or import your configs

No VM to download, no server to configure. Just app.netpilot.io. Or import existing Cisco device configs to start from a real network.

app.netpilot.io
2

Describe your lab — AI designs and deploys it

“Build a 4-router OSPF lab with VLANs” — the AI generates the topology, assigns IPs, writes Cisco IOS configs, and deploys to cloud-hosted ContainerLab.

3

SSH into real Cisco CLIs and validate

Your lab deploys in minutes. SSH into real Cisco IOL routers and switches (bring your own Cisco image) from your browser — run show commands, configure routing, troubleshoot. Real IOS, real behavior.

Where NetPilot fits vs Cisco virtual labs

Pick Cisco CML / GNS3 / EVE-NG when you need:

  • •Cisco CML is right if you specifically need Cisco's canonical reference emulator with official Cisco IOS images
  • •GNS3 is right if you need fully offline operation on a 32 GB RAM workstation you own
  • •EVE-NG is right if your team already runs a shared EVE-NG server with curated images
  • •Physical hardware is right when you need vendor-certified production testing

Pick NetPilot when you need:

  • •AI-generated Cisco IOS configs + multi-vendor topology design from plain English
  • •Real Cisco IOL CLIs in the cloud via BYOI — no VM with nested virtualization, no 32 GB RAM workstation
  • •Multi-vendor alongside Cisco: Juniper, Arista, Nokia, Palo Alto in one topology
  • •No 5-node cap (CML Free) and no $199/year license gate
  • •Minutes from prompt to working Cisco lab — browser-only

Verdict:CML, GNS3, and EVE-NG remain the right choice for specific offline or Cisco-reference-only needs. NetPilot is the cloud + AI-native choice for teams who want real Cisco IOL CLIs combined with multi-vendor topologies from plain English.

Frequently Asked Questions

Common questions about Cisco virtual labs

A Cisco virtual lab is a software environment that runs real or simulated Cisco devices — routers, switches, firewalls — without physical hardware. Options include Cisco CML ($199/year for 20 nodes), GNS3 (free, requires 32GB RAM server), EVE-NG (free community / 150 EUR Pro), and NetPilot (free tier, cloud-hosted with AI). NetPilot runs your Cisco IOL image (bring-your-own-image) in the cloud with AI-powered configuration — no VM, no server.
Yes. GNS3 is free but requires your own hardware (32GB RAM recommended) and Cisco IOS images. Cisco CML Free is limited to 5 nodes. NetPilot offers a free tier with cloud-hosted Cisco IOL devices (bring your own Cisco image) and AI-powered lab generation — no hardware, no server.
Yes. NetPilot runs your Cisco IOL image (bring-your-own-image) on cloud-hosted ContainerLab — access real CLIs from any browser. CloudMyLab offers hosted EVE-NG from $23/week. You can also self-host GNS3 or CML on cloud VMs, but you manage the infrastructure yourself.
CML is self-hosted — you download a VM, install it, manage it locally. CML Free is limited to 5 nodes; Personal costs $199/year for 20 nodes. Cisco only. NetPilot is cloud-hosted with an AI agent that generates topologies from plain English. No VM, no installation. Supports 9+ vendors (and growing).
GNS3 needs 32GB RAM recommended. EVE-NG requires a dedicated server (16GB RAM minimum). CML requires a VM with nested virtualization. NetPilot requires nothing — runs on cloud infrastructure, accessible from any browser.
Yes. Virtual labs running real Cisco IOS (GNS3, CML, NetPilot) give you full CLI access — show ip route, show ip ospf neighbor, configure terminal, and every other IOS command. The behavior is identical to physical hardware.
Start with Cisco Packet Tracer for basics (free, simple). For real IOS practice, use GNS3 (free, requires setup) or NetPilot (free tier, cloud-hosted, AI-generated labs). CML Free works but the 5-node limit blocks most useful CCNA labs.
Yes. NetPilot's enterprise plan includes a self-hosted / on-prem deployment option for Cisco-focused teams with local-hosting or data-residency compliance requirements. Run Cisco IOL + multi-vendor labs on your own infrastructure. The cloud product is the default self-serve; on-prem is available via Contact Sales.
