Real Vulnerable Websites Included
Each web challenge gives you a real deployed vulnerable web application to attack — login pages, APIs, admin panels, e-commerce sites and more. No simulations — actual HTTP requests, actual exploits, actual flags.
Our AI Guided Solver watches you hack — and when you're stuck, it automatically runs the right tools, shows every command, explains each step, and teaches you how the vulnerability works. You don't just get the flag — you learn exactly how it was found.
Auto-Enumeration
AI runs nmap, gobuster, nikto automatically on the target and maps all attack surface.
Smart Exploit Selection
Picks the right tool (SQLMap, Burp, Hydra) based on what it finds — no manual guessing.
Learn While You Watch
Every command is explained. See WHY each step is taken, not just what to type.
Flag + Full Writeup
Get the flag AND a full step-by-step writeup you can save and revisit later.
