Free · in the browser
Learn Linux online. No setup, real cloud VM.
A real Linux terminal on your own cloud VM — right in the browser. Solve exercises, get them checked automatically, learn server hardening for real. Free, GDPR-compliant, hosted in Germany.
Why it's different
Real VM beats emulator
Real cloud VM, not an emulator
Your own Linux machine in the cloud — not a sandboxed JavaScript fake. Real commands, real consequences, real learning.
Automatic task checks
Every exercise is verified on the live VM. You see immediately whether your solution actually works — no guessing.
No installation

Hosted in Germany, GDPR-compliant
VMs run on German Hetzner servers. For schools: data processing agreement, class-code login without student email.
