Multi-Vendor Network Labs

Cisco CML AlternativeMulti-Vendor, No Node Limit, No License

The cloud-native AI-powered alternative to Cisco Modeling Labs.

Skip the local VM with nested virtualization, the 5-node free-tier cap, and the Cisco-only lock-in. Describe the topology in plain English, NetPilot's AI writes per-vendor configs, lab deploys in ~2 minutes from any browser. SSH into any device to verify — agent for speed, classic CLI anytime you want to drill in by hand.

No node limits on any tier
Multi-vendor — not Cisco only
AI-designed labs in ~2 minutes
Free tier — no license required

How NetPilot differs from Cisco CML

CML is a solid Cisco-only VM-based emulator. NetPilot combines cloud-native + AI-designed + multi-vendor + no node cap in one product — different bet, different use case.

Cloud-native

Browser only. Nothing to install.
The alternativeCML requires a local VM with nested virtualization + 16-32 GB RAM. Not available on most cloud providers or locked-down laptops.

AI-designed

Describe any multi-vendor topology in plain English. AI designs + generates per-vendor configs + deploys.
The alternativeCML is drag-and-drop GUI + per-device Cisco CLI by hand. No AI, no natural-language design, no multi-vendor syntax help.

Multi-vendor + multi-turn

"Add an Arista spine alongside the Cisco core" — AI updates across vendors. 9+ NOSes (and growing) in one topology.
The alternativeCML is Cisco-only (IOS, NX-OS, ASAv). No Juniper, no Arista, no Nokia, no Palo Alto. Every change manual per device.

2 minutes + no node cap

~2 minutes from prompt to working lab. No node limits on any tier.
The alternativeCML Free caps at 5 nodes. Personal $199/year unlocks 20 nodes. Setup takes hours; every config is typed by hand.

CML Limitations NetPilot Solves

CML is a solid tool — but the node limits, licensing, and Cisco-only lock-in hold you back.

5-Node Limit on Free Tier

CML Free caps you at 5 simultaneous nodes — a basic OSPF lab with 3 routers, 2 switches, and hosts already exceeds it. NetPilot has no node limits on any tier.

$199/Year License Unlocks Only 20 Nodes

CML Personal costs $199/year for 20 nodes. Enterprise pricing goes higher. NetPilot offers a free tier with no node cap and usage-based plans — multi-vendor support included.

Cisco Devices Only

CML only supports Cisco IOS, NX-OS, and ASAv. No Juniper, no Arista, no Nokia, no Palo Alto. NetPilot supports 9+ vendors (growing via community GitHub requests; enterprise BYOI for custom vendors).

VM + Nested Virtualization Required

CML requires a VM with nested virtualization support — not available on all hardware or cloud providers, and incompatible with most locked-down work laptops. NetPilot is fully cloud-hosted, accessible from any browser.

NetPilot vs Cisco CML

Multi-vendor, AI-powered, and cloud-hosted — without the licensing overhead or the 5-node cap.

How NetPilot Works

No VM, no license, no Cisco-only limitation. Just describe and practice.

1

Describe Your Lab

"Build a 4-router OSPF lab with multi-area and redistribution" or "Create a multi-vendor BGP lab with Cisco and Juniper" — just describe it.

2

AI Builds Multi-Vendor Topology

NetPilot's AI generates the topology, assigns IPs, and writes vendor-specific configs — Cisco IOS, Nokia SR Linux, Arista EOS, and more. No manual config, no node cap.

3

Practice on Real CLIs

SSH into real devices from your browser. Run show commands, troubleshoot routing, iterate via natural language — with the AI agent when you get stuck.

Everything You Did in CML — And More

Bottom line

Pick Cisco CML when you need:

  • •Your workflow is 100% Cisco IOS / NX-OS / ASAv
  • •You already own a CML Personal license and compatible local hardware
  • •You need fully offline operation on your own workstation
  • •You want the canonical Cisco reference emulator exactly as Cisco ships it

Pick NetPilot when you need:

  • •Multi-vendor topologies in one lab (Cisco + Juniper + Arista + Nokia + Palo Alto)
  • •AI-designed topologies + per-vendor configs from plain English
  • •No node limits on any tier — build labs as big as you need
  • •Browser-only: no VM, no nested virtualization, no 16-32 GB RAM requirement
  • •Multi-turn natural-language iteration across all devices

Verdict:Cisco CML is the right tool if you need the canonical Cisco-only emulator on owned hardware with a Personal license. NetPilot is the 80% case — multi-vendor labs in 2 minutes, AI-designed, no node cap, no license, browser-only.

Frequently Asked Questions

Common questions about switching from Cisco CML to cloud-native AI-powered network labs

NetPilot combines cloud-native (browser only, no VM with nested virtualization), AI-designed topology (describe it in plain English — AI generates per-vendor configs), multi-vendor in one topology (not Cisco-only), and multi-turn natural-language iteration. CML is the right choice when your workflow is Cisco-only and you already own a Personal license on compatible hardware. NetPilot is the 80% case — anyone who wants multi-vendor labs without the node limit or license.
NetPilot is the cloud-native AI-powered Cisco CML alternative for engineers who need multi-vendor support and AI-designed labs. Unlike CML's 5-node free-tier cap and Cisco-only scope, NetPilot has no node limits, supports 9+ network vendors (growing), and generates complete topologies from plain English descriptions. Free tier available with no license required.
Yes. CML Free limits you to 5 simultaneous nodes, which is not enough for most meaningful labs. NetPilot has no node limits on any tier — build labs with 10, 15, or more devices. The free tier includes AI-powered lab design and configuration generation with no node cap.
Yes. NetPilot supports Cisco IOL routers and L2/L3 switches via one-click image upload. You download the Cisco IOL image and upload it to NetPilot — the platform automatically builds and verifies the Docker container. Unlike CML, NetPilot also supports Nokia SR Linux, Arista cEOS, Juniper cRPD, Palo Alto, Fortinet, and FRRouting.
Yes. NetPilot is the cloud-native AI-powered Cisco CML alternative — no VM, no nested virtualization, no node cap. Supports 9+ network OSes (Nokia SR Linux, FRR, Linux built-in; Cisco IOL, Juniper cRPD, Arista cEOS, Palo Alto, Fortinet via BYOI) and generates working per-vendor configurations automatically from plain English. CML requires a local VM with nested virtualization and caps Free at 5 nodes. As of 2026, NetPilot is the productized cloud + AI-native combination for CML users who need multi-vendor topologies without the VM.
CML is Cisco-only with licensing requirements and node limits. NetPilot is AI-powered, multi-vendor, and cloud-hosted. With CML, you manually build topologies and configure devices. With NetPilot, you describe what you need in plain English and the AI generates everything — topology, IP addressing, and vendor-specific configs for Cisco, Juniper, Arista, Nokia, and more.
Yes. NetPilot covers all CCNA and CCNP lab scenarios — OSPF, EIGRP, BGP, VLANs, STP, ACLs, NAT, and more. Describe any lab and practice on real Cisco IOL CLIs. You can also import existing .pkt files, modify them with AI, and re-export — or export fresh topologies as Cisco Packet Tracer .pkt files for offline practice.
Cisco VIRL was replaced by Cisco Modeling Labs (CML) in 2020. CML continues the same approach — Cisco-only devices with licensing. NetPilot is a modern alternative that adds AI-powered lab generation, multi-vendor support, and cloud hosting with no license fees.
Cisco CML runs as a local VM with nested virtualization support — it's the official Cisco answer and stays the right choice if you want Cisco-sanctioned IOS-XE/NX-OS/IOS-XR fidelity on owned hardware. CML Free is capped at 5 nodes; Personal is $199/year for 20 nodes. As of 2026, NetPilot is the productized cloud-hosted, browser-based alternative in this category — no local VM, no node cap; describe your lab in plain English and the AI generates the topology and configs (including real Cisco IOL devices).
Yes. NetPilot's enterprise plan includes a self-hosted / on-prem option for teams whose workflow requires local hosting (compliance, data residency, or air-gapped networks) — same local-hosting model as CML, but multi-vendor with an AI agent writing configs. Cloud-hosted is the default self-serve product; on-prem is available via Contact Sales.
