Gamified hacking. Learn it like a game.
It's Duolingo, for hacking. Bite-size lessons, a daily streak, XP, levels and a weekly league, wrapped around the dark fun stuff, cracking WiFi, taking over accounts, downing a store, all in a sealed, legal sandbox in your browser.
The app that makes hacking a habit.
A lesson, then a real attack.
Lessons teach the command. Labs make you run it against a live simulated target that reacts to what you did. Here is one of each, exactly as they play on your screen.
The dark fun stuff.
The attacks behind stolen accounts, drained wallets and downed sites, taught the only responsible way: you run them yourself, against fictional targets, so you finally understand how they really work and how to stand in their way.
HardSee exactly how a stolen login really happens, from profiling the target to intercepting the second factor, so you know what protects yours.
MediumTrace what an infostealer took: saved passwords, cookies, live sessions. The chain behind most crypto and account theft, laid bare.
HardFind the one bottleneck that drops a whole shop, and the capacity math a defender uses to keep it standing.
HardScan the block, force a reconnect, capture the handshake, break the key, and understand why a weak passphrase is the whole game.
HardRead her real socials, write the email, and watch a synthetic person decide whether to click. This is how most breaches actually start.
MediumFind the injectable field and read the users table behind a login, the bug that has leaked more passwords than any other.
HardOne rig, one timer, three locks. Turn a hash back into the word behind it and feel why length beats symbols.
HardTalk a company chatbot past its own guardrails and out its secrets, the newest attack surface on the internet.
30 labs and 289 lessons across 54 disciplines. Every system is simulated; nothing you do ever touches a real person or network.
Level up. Climb the league. Beat your rival.
Every lesson and lab earns XP. XP levels you up, ranks you in a live weekly league of ten, and feeds a head-to-head with a rival who is grinding the same skills you are.
From zero to zero-day
Scroll the road — each skill loads to 100% as you reach it.
The honest answers
Is it really like Duolingo?
Same idea, different subject. You get bite-size lessons, a daily streak, XP, levels and a weekly league of ten, so the thing that keeps you coming back to a language app keeps you coming back to hacking. The difference is that every lesson ends in a real command you ran, not a phrase you repeated.
Do I need to know how to code?
No. The first lessons build commands from blocks you drag into place, so you learn what each part does before you ever type one from memory. Coding helps later; it is not the entry fee, and it is the exact wall most people quit at.
Is learning this stuff legal?
Yes, because you never touch anything real. Every target is invented: synthetic people, synthetic companies, sealed networks, all running inside your browser. Doing these same things to a system you do not own is a crime, so the sandbox is the whole point.
What can I actually learn to hack?
30 scenarios in total: cracking WiFi, phishing a finance team, account takeover, taking a store offline, breaking a database, cracking passwords, tracing an infostealer, jailbreaking an AI, and more. Each is a full simulated operation that reacts to what you actually do.
Is it free to start?
The first path is free, and the trial runs 7 days with nothing charged today. The darker disciplines and the daily labs unlock on a plan, from EUR 6.90 a month, when you are ready for them.
