Real environments, not toy sandboxes
A real IDE, a real Jupyter notebook, a real vulnerable network. The tools open in your browser — nothing to install, nothing faked.
CyberKul — learn tech skills by doing. Build software, grow a company, train models, break real machines — all in your browser.
cyberkul — the modern gurukul
cyberkul is a gamified, hands-on platform where you build real software, grow a real company, train real models, and break into real machines — then earn the XP, streaks, badges and certificates to prove it.
No slides. No toy sandboxes. Just the work.

Why cyberkul
Skills compound when you do the work.
Watching a lecture feels like progress. Shipping a passing test, closing a funnel, or capturing a flag is progress. We built the whole platform around the second one.
[02]
Learn by doing, graded for real
Every exercise runs. Run the visible tests, submit your solution, capture the flag by hash. You get signal, not a participation checkmark.
[03]
Progress you can measure
XP, levels, streaks, leagues and a leaderboard turn "I studied" into a number that moves — and a certificate you can actually verify.
// try it now — no signup
crack your first flag.
Every lab ends in a flag — a secret string you capture to prove you solved it. Warm-up: the flag below is Base64-encoded. Decode it, paste the result, and capture your first flag — right here, no account needed.
ENCODED FLAG

Hint: it's Base64. Decode it in a terminal (echo '…' | base64 -d), the browser console (atob('…')), or any online decoder.
✓ Flag captured. That's challenge 01 of 250+. Ready for the rest?
The game layer
Every rep earns something.
Progress isn't a vibe here — it's a system. Earn XP on every solve, keep the streak alive, climb your league, and unlock badges that mean you actually did the thing.

Solo or as a team — every metric rolls up to your classroom or org.
The loop
Do. Earn. Climb.
One simple loop under everything — the more you do, the more it compounds.
01 / DO
Open a real environment and do the work.
A live IDE, notebook, or vulnerable network spins up in your browser. You write real code, run real tests, capture real flags — instantly, nothing to install.
02 / EARN
Every solve pays out XP, badges and streaks.
Graded for real — tests must pass, flags verify by hash, models score on a hidden holdout. Signal you can trust, rewards you can see.
03 / CLIMB
Level up, climb your league, get certified.
Ride the leaderboard, hold your league, and turn a run of solves into a verifiable certificate you can share.
For organizations
Bring the whole cohort.
cyberkul runs solo or as a team. Spin up a classroom, assign tracks, and watch a live roll-up of who's doing the work — across universities, bootcamps and engineering orgs.
Built for

Questions, answered
Before you start.
The things people actually ask on the way in.
No. Every environment — the IDE, the notebook, the live labs — runs in your browser. If you can open this page, you can start doing real work in the next minute. Nothing to download, nothing to configure.
Yes. You can create an account and do your first labs free — no credit card. Paid plans unlock unlimited labs, every discipline, and team features, but you'll do real work before you ever hit a paywall.
Yes. Complete a track and you earn a verifiable certificate you can share on a portfolio, a résumé, or with your school. Because everything is graded for real — tests pass, flags verify by hash, models score on a hidden holdout — the certificate actually means you did it.
Real practice. You write real code in a real IDE, grow a real company simulation in Market, train real models in a notebook, and break into real vulnerable machines in Defend. No multiple-choice, no toy sandboxes — you do the actual work and it's graded.
Absolutely. Classroom mode lets you invite a cohort, assign disciplines, run private leagues, and see a live roll-up of everyone's XP, streaks and completions. It's built for universities, bootcamps and engineering teams who want hands-on curriculum and onboarding.
Every solve pays out XP toward your level. Do something each day to keep your streak alive. Weekly leagues group you with peers at your pace, and a global leaderboard tracks the top of each discipline — so practice always has a scoreboard.
