IzzyLab gives you a real Linux machine with root access right in your browser and 500+ hands-on tasks - from basic commands to nginx, PostgreSQL, Kubernetes, Ansible and Terraform. No emulators, no multiple-choice quizzes: solve each task any way you like and one-click checks verify the result, not the commands you typed. Broke the system? Reset and get a fresh sandbox. Includes story-driven incidents where you hunt down and fix what broke production.
