Hackr.gg is a browser-based platform for learning offensive web security by doing. 85 hands-on modules mapped to the OWASP Top 10 - XSS, SQL injection, IDOR, SSRF, JWT attacks, command injection and AI/LLM red teaming - each with a vulnerable app you exploit right in the browser. No VPN, no attack box, no setup. Guided lessons, inline labs, career paths and badges take beginners from zero to job-ready, and the HJPT certification offers a practical, exam-based credential. Team plans available.
