Interactive Security Lab

SQL Injection Simulator

Pick an attack, craft an input, and watch exactly how it rewrites the database query — then read what happened and how to stop it. Nothing here touches a real database or the network; every query runs against an in-memory mock, entirely in your browser.

This is a teaching tool. Every "database" here is a hard-coded JavaScript object in your own browser — no query is ever sent anywhere, and there is nothing real to exploit. Only ever test SQL injection against systems you own or are explicitly authorized to assess.
