Learning platform
Learn server hardening — free, in your browser, with a real Linux VM
No installation. No VM-setup hours. No expensive online courses. You click, get your own Ubuntu VM, harden it task by task — and the validator checks every step.
- GDPR-compliant
- Made in Germany
- Servers in Germany (Hetzner)
- TLS-encrypted
- No tracking without consent
How it looks
A real Linux terminal in your browser
No simulation, no fake. You SSH into a Hetzner Cloud VM and the validator checks every step.

Lab catalogue
Lab modules
Each module spawns a fresh Linux VM and verifies your work automatically.
How it works
Three clicks to your own VM
- 01
Sign up
Email + password + year of birth. Learners under 16 need parental consent (GDPR Art. 8).
- 02
Start a module
Click a module → a Hetzner Cloud VM is provisioned in 60–90s. You land directly in the browser terminal.
- 03
Solve tasks
Each task has a “Check” button. The validator inspects your config state and returns instant feedback — passed, failed, or hint.
Power user
Also in the terminal — the Techlogia CLI
Start lab modules, manage sessions, administer classes — straight from your terminal. Persona-aware: shows only the commands your role is actually allowed to run.
Install
Node 18+ · macOS / Linux / Windows · JWT in your OS keychain
What you can do in the terminal
- Browse modules, read lessons in Markdown, spawn and terminate VMs
- Learner, student (class code), teacher, school admin, platform admin
- Scriptable for CI / class onboarding — e.g. bulk-import 30 students
- German and English, output rendered via marked-terminal for rich reading

Safety & data protection
Built safely — GDPR-compliant, hosted in Germany
Data protection is mandatory, not a feature. Lab runs GDPR-compliant with a data-processing agreement for schools, hard sandbox boundaries and 24/7 monitoring — and collects parental consent for underage learners.
Fully isolated VMs
Each learner gets their own Hetzner Cloud VM with an external firewall. No contact between sessions, no access to the Techlogia network.
Parental consent under 16
GDPR Art. 8 / BDSG: Learners under 16 require parental consent. We email parents a separate confirmation link.
Mining + DDoS detection
CPU and bandwidth watchers run every 5 minutes — crypto mining or reflection-DDoS kills the VM automatically.
GDPR-wipe with one click
Delete your account from the profile — all sessions, logs and learning progress are removed instantly (GDPR Art. 17).

For schools
Bring the lab to your classroom
Teachers get classes, students log in with a class code — no email setup, no passwords. GDPR-compliant under a DPA agreement with your school.
01
School onboarding
Sign the DPA, get a school admin account. Add teachers from there.
02
Class code
Teacher creates a class, gets a code like KLAS-7H3KX9P, hands it out.
03
Students log in
Code plus their login name. Teacher sees progress per student.
Ready?
One VM, three modules, no setup. All you need is a browser.
