What the lab includes

  • 100+guided labs
  • 400+faults to troubleshoot
  • 900+exam questions
  • 10+vendors & platforms
01 · coverage

Truly multi-vendor

From OSPF routing on a Cisco switch to FortiGate, from Linux to IBM i and Siebel. The enterprise and legacy stacks others don't touch.

02 · access

Zero install

Everything in the browser, on any machine. No VM, no dedicated hardware, no environment setup.

03 · licensing

Legally clean

We simulate how the devices behave, we don't copy their firmware. Nothing to download, no grey area.

04 · method

You actually learn

Guided labs, real faults to diagnose and hands-on exam questions, all in one environment.

// simulated devices

A whole topology, configured line by line.

Every device answers with its own CLI, its system messages and its network behavior. You wire them up, configure them, and the traffic flows — or it doesn't, if there's an error to find.

// the command line

You learn by typing, not clicking.

The craft of the sysadmin and the network engineer happens at the terminal: you configure, diagnose and automate with commands, not with the mouse. Here every system answers with its real shell — Windows Server too, from PowerShell and CMD, not from a window. It's how you work in the field, and exactly what the exam asks of you.

CMD · PowerShell · Bash · Cisco IOS · FortiOS · RouterOS · PAN-OS · ArubaOS-CX · IBM i CL. The same syntax as the real job — no mouse shortcuts, no dumbed-down environment.

// method

Three ways to train, in one place.

Not just a place to tinker: a path that takes you from guided configuration all the way to diagnosing a fault whose location you don't yet know.

Guided labs

Scenarios with clear goals and automatic checking: you configure, you verify, and the lab tells you whether the result is correct.

Fault troubleshooting

The lab injects a real fault — a disabled policy, a missing route, a wrong fstab — opens a ticket and closes it when you actually fix it.

Exam questions (PBQ)

Hands-on tests in certification-exam style: not multiple choice, but carried out on the device, with a score.

Coming soon · Real-time shared lab — several people on the same lab: one configures the router, the other the client.
// the difference

Simulation, not emulation. A choice, not a limit.

Emulators load the vendors’ real firmware. Powerful, but heavy — on hardware, on setup time and on the legality of the images. We rebuild the behavior: same learning, none of the weight.

Emulators with real firmware

  • — You have to source the vendor images: licenses to own, often a grey area.
  • — A server or VM with lots of RAM: no Chromebook, no "open and go".
  • — A long setup before you write the first command.
  • — No learning path: the environment is there, the method isn't.

PractiCLI

  • + No firmware images: nothing to download, no license risk.
  • + Runs in the browser on any machine, even a light one.
  • + Ready to use: the topology is already there, you start right away.
  • + Guided faults and PBQ built in: you learn to fix, not just to click.

// questions

The things people usually ask us.

Do I need to install anything?
No. The lab opens in a browser tab. No VM, no firmware images, no special hardware requirements: it works on light machines and Chromebooks too.
Is it legal? Are you affiliated with the vendors?
Yes, it's fully legitimate. The environment is entirely our own production: we rebuilt the command-line behavior from scratch in a fully virtual engine. It does not run, emulate, copy or distribute any manufacturer's firmware, operating system or software. We are not affiliated with or endorsed by Cisco, Fortinet, MikroTik, Palo Alto Networks, HPE Aruba, Microsoft, IBM, Oracle or any other vendor: their trademarks belong to the respective owners and are cited only to describe the technologies you can practice. All scenarios, exercises and exams are our original works.
Can I share my subscription?
The subscription is personal: one seat, one user. Each account has a single active session at a time and a device limit.
Do I need to be online?
Yes: signing in requires authentication, so the subscription stays protected and yours. Once inside, the environment runs entirely in your browser and is responsive.
Which certifications can I prepare for?
Hands-on practice for routing & switching, enterprise networking, security and firewalls, Linux and systems administration — across several vendors. It's useful to prepare for tracks such as CCNA and CCNP, Linux+ and CompTIA A+, and firewall and MikroTik tracks. The PBQ-style questions mirror the performance-based, hands-on tasks you meet in the real exams.
What's included with Pro versus the free demo?
The free demo lets you try the environment on a limited set of labs, with no card required. Pro unlocks the full multi-vendor catalog: all the labs, the fault and troubleshooting scenarios, the guided solutions and the exam and PBQ practice. Protected content (solutions, scoring) is delivered encrypted, just for your session.
How realistic is it? Is it enough to pass the exam?
You practice on a faithful reconstruction of the real command line and of performance-based exam tasks, with instant feedback and graded exercises. It's a strong complement to your study and to time on real or official equipment — but no lab or course can guarantee a certification result: the official exam is sat at the vendor's test provider.
How does payment and access work?
It's a one-time purchase that unlocks access for a fixed term. Payment is sold and invoiced by Lemon Squeezy, our Merchant of Record, which handles taxes and payment data — we never see your card details. Access begins immediately and the purchase is final. There is no automatic renewal: when your term ends, access simply expires and you can purchase again to continue. Full details in the Terms.
Is my data safe and private?
Yes. Passwords are hashed and never stored in clear text, sensitive content is encrypted, sign-in uses short-lived tokens, and card details are handled only by our payment provider. We keep just what's needed to run your account and protect your subscription. See the Privacy Policy.
