Problem

Security training tools are either too passive or require a painful local setup. People drop off before starting.

Approach

One click spins a container. Real targets, real flags. Walkthroughs unlock only after solving — forward momentum, no passive reading.

Outcome

Live and running. 60+ labs across SQL injection, XSS, IDOR, JWT attacks, SSRF, and more.
