Practice Real
Infrastructure
Not Theory
The hands-on practice platform for DevOps and SRE engineers. Real challenges. Real terminal. No cloud sandbox needed.
No spam. We'll notify you when we launch.
We built this because nothing else worked.
Cloud sandboxes cost money, take forever to spin up, and break when you need them most. Certifications test memorization, not muscle memory. Tutorials walk you through happy paths that never match production.
Open a terminal. Get a problem. Solve it.
The same way you do it at work. No setup. No credit card. No environment that drifts from reality.
Three ways to practice
Run commands in a live terminal. Deploy containers, configure services, see changes take effect.
Investigate broken systems. Read logs, trace root causes, prove the why.
Write Dockerfiles, Terraform configs, shell scripts. Graded on correctness and best practices.
Interactive Terminal
Real commands in a simulated environment. Docker, kubectl, terraform. The tools you already use.
Production Scenarios
Multi-step challenges pulled from real incidents. Not multiple choice. Real problem solving.
Approach-Based Scoring
Your methodology matters, not just the final answer. See where your thinking has gaps.
Seven Domains
Docker, Kubernetes, Terraform, Git, SQL, Python, npm. Plus cross-domain scenarios.
Instant Feedback
No provisioning. No drift. Feedback on every command as you work.
Docker · Kubernetes · Terraform · Git · SQL · Python · npm
Built by an engineer,
for engineers.
Not a content team. Not a marketing agency.
Why not just use a cloud sandbox?
They're expensive, slow to spin up, and break constantly. We give you the same command-line experience with instant feedback and zero infrastructure costs.
How is this different from LeetCode?
LeetCode is algorithms. Infrastructure is about state: what happens across a sequence of commands, how systems interact, how to diagnose failures. Different problem, different platform.
Who is this for?
DevOps engineers prepping for interviews. SREs sharpening skills. Teams onboarding new hires. Anyone expanding into Kubernetes, Terraform, or Docker.
