Prove you can do the job before anyone gives you one.
Free, real-world networking challenges. Solve them in a real lab, get your work checked against a live network, and earn a verified proof of work you can show employers. No experience required to start. That's the point.
Opens a real network in your browser. Or see an example proof.
“You need experience to get the job, and a job to get experience.”
Cert courses teach theory. Job sims are fake. And a résumé can't show that you can actually make a network work. We fix that.
How it works
- 01
Pick a real challenge.
BGP won't converge. A VLAN can't route. Automate OSPF across three routers. Real scenarios, not puzzles.
- 02
Build it and submit.
Solve it in a free lab on your own machine, then submit your work as a public repo.
- 03
Get verified instantly.
Your real config is checked against a live validation suite — pass, and a verified proof page is issued on the spot. Want a human's eyes? Submit your own lab for expert review.
Why it's different
Real work, not simulations.
You build it; we verify it actually runs in a real topology.
Checked for real.
Not a multiple-choice quiz — your actual config runs against a live validation suite that confirms the network really works.
A proof page employers trust.
It links back to exactly what you were asked to do, and shows your solution passed the checks.
Build proof you can point to.
Open a live lab and fix a real network right now, no account needed until you've earned a proof.
