Networking · verified proof-of-work

Prove you can do the job before anyone gives you one.

Free, real-world networking challenges. Solve them in a local lab, get expert feedback, 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

  1. 01

    Pick a real challenge.

    BGP won't converge. A VLAN can't route. Automate OSPF across three routers. Real scenarios, not puzzles.

  2. 02

    Build it and submit.

    Solve it in a free lab on your own machine, then submit your work as a public repo.

  3. 03

    Get verified + feedback.

    We confirm it actually works, give you real feedback, and issue a verified proof page you can link anywhere.

Why it's different

Real work, not simulations.

You build it; we verify it actually runs in a real topology.

Real feedback.

From someone who's done the job, not an auto-graded multiple-choice quiz.

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.
