How it works

From zero to production-ready in three steps

Step 1

Choose your tier

Junior, Semi-Senior, or Senior — each tier unlocks 15 exercises calibrated to your experience level, from Linux fundamentals to full production architecture.

Step 2

Start a real cloud lab

One click provisions a fresh, security-hardened cloud server. You get a browser terminal, a broken system, and a hard time limit. Fix it before the clock runs out.

Step 3

Get graded and earn your report

Our validation engine scores every check the moment you submit. Track your progress, download PDF reports, and prove you can run production.

Features

Everything you need to practice like it is production

A complete training ground: real infrastructure, real failure modes, real feedback.

Real Cloud Servers

Every lab spins up a genuine cloud VM — not a simulation. SSH in from your browser and work like you would on any production box.

Auto-Grading

A validation engine checks your work the second you submit: services running, ports open, configs correct. Instant, fair, detailed.

Progress Reports

Category and tier reports break down every check, score, and minute spent. Download them as PDFs and share your proof of skill.

Time-Boxed Labs

Hard time limits mirror real incident pressure. When the clock hits zero, the box is destroyed — no extensions, no excuses.

Multiple Categories

Linux, web servers, networking, containers, CI/CD, monitoring, HA, security, disaster recovery, and architecture — 45 labs across 15 categories.

FAQ

Frequently asked questions

Everything else you might want to know before your first lab.

repairprod is a practice platform for DevOps and infrastructure engineers. When you start a lab, we provision a real, disposable cloud server with a broken or incomplete setup. You fix it over an SSH connection in your browser, submit your work, and our validation engine grades it instantly.
No. All sandbox servers run on our infrastructure. Your subscription covers unlimited lab attempts within your tier — you never pay for compute, and you never receive a cloud bill.
The lab has a hard time limit. When time expires, we run the validation script one final time, score whatever state the server is in, and then destroy the server immediately. You can retry the exercise as many times as you like.
Yes — that is the whole point. Every sandbox is isolated, firewalled, and destroyed after use. It cannot reach our internal systems or the wider internet beyond what the exercise needs. Break it, fix it, learn from it.
If you have 0–2 years of experience, start with Junior. With 2–5 years, Semi-Senior is the sweet spot. Senior is for engineers comfortable with high availability, security hardening, and architecture work. You can upgrade anytime and billing is prorated.
You can cancel your subscription at any time from your dashboard — you keep access until the end of the current billing period. If something went wrong with a payment, our refund policy covers the first 14 days of any new subscription. See the refund policy for details.
Yes. Completing a category or a full tier generates a detailed report with per-exercise scores, individual check results, and time spent. Tier-completion reports are downloadable as PDF certificates you can share with your team or on your profile.
