A game where you run through a server farm, open terminals and type the real commands to bring production back online. Built for DevOps and SRE interview prep.
No signup. Runs in your browser, on desktop or phone. First 3 incidents free.
Every level is a production incident. You don't pick A, B, C or D. You type the command.
Ada, your on-call lead, tells you what's down. Run and jump through the level, stomp the bugs.
Open four terminals: find the cause, apply the fix, verify it. Wrong commands teach you why they're wrong.
Each level ends with the root-cause question and a command cheat sheet to remember for interviews.
Disk, memory, CPU, permissions, networking, firewalls, SSH and more. More worlds (Docker, Kubernetes, CI/CD, Terraform, AWS) are on the way.
One payment. Your license key is emailed right after.
No. The terminals are simulated, so there's nothing to install and nothing can break. But the commands, flags and outputs are the real ones you'd use on-call.
Yes. There are on-screen controls and a touch keyboard for the terminals. A laptop is more comfortable for typing.
After payment your license key is emailed to you. Open the game, click "Unlock all levels" and paste it. Your progress is saved in your browser.
Anyone preparing for DevOps, SRE, sysadmin or cloud interviews, and new engineers who want on-call practice.
