Built for Production Engineering

Simulate complex production outages and system failures in a safe, isolated environment.

Kernel Level Access

Debug system calls, kernel panics, and network stacks. It's a real Linux PC, not a container.

Practice Safely

Wipe the root partition? rm -rf /? No problem. Each session is a disposable MicroVM.

Scenario Training

Learn by doing: Fix broken Nginx configs, resolve port conflicts, and mitigate resource exhaustion.
