Frequently asked questions
What is Zynergy Labs?
A place to practice Linux and DevOps troubleshooting. Each scenario gives you a real server with something broken; your job is to find the problem and fix it.
Do I need to install anything?
No. The terminal runs in your browser, so a laptop and an internet connection are enough.
How long is a session?
Each scenario has its own time limit, shown in the table above. Pro members get 2× that time.
Is it really free?
Yes. A Free account gets 3 sessions a day on the Free scenarios, with no credit card.
What's the difference between Free and Pro?
Pro unlocks every scenario, removes the daily cap, gives you 2× the time and keeps your command history after each session.
What happens to my lab afterwards?
It is deleted when the session ends, so every start gives you a fresh server.
