We're building a LeetCode-style system design lab. You learn by designing systems, watching them break, and fixing them under real constraints.
System design is one of the most important skills for software engineers, but there is no real place to practice it. You can grind algorithms on LeetCode. You can solve CTFs for security. For architecture, you read blog posts, watch videos, and hope for the best.
SystemForces changes that. We provide a simulation environment where you drag and drop real infrastructure components (load balancers, databases, caches, queues), wire them together, and watch traffic flow through your design. Then we stress it with traffic spikes, node failures, and injected latency. Your score shows how well your architecture holds up.
Practice with consequences. That's what we're building.
The principles that drive every decision we make.
Real understanding comes from failure. Our simulations add chaos like traffic spikes, node crashes, and region outages, so you learn what matters in production.
No hand-wavy feedback. Every design is scored across latency, availability, cost, and complexity. You know exactly where you stand and how to improve.
Start simple. Each level adds new constraints like budget limits, latency caps, and failure scenarios. Difficulty scales with your skill.
Whether you're a CS student, a self-taught developer, or a bootcamp grad, SystemForces meets you where you are.
Same inputs, same results. Every simulation run is reproducible, so you can iterate, compare, and truly understand the impact of each change.
Public profiles, leaderboards, and badges. Share your best designs, compare approaches, and climb the ranks alongside a global community.
How SystemForces came to be.
We noticed the gap: millions of engineers prep for system design interviews by reading static diagrams and memorizing patterns. There was no way to actually build, test, and iterate on designs with real feedback.
We asked: what if you could drag and drop infrastructure components, wire them up, simulate traffic, and get scored, like competitive programming but for system design?
One scenario. Five levels. Fifteen infrastructure blocks. A deterministic simulation engine. Enough to prove the concept and validate that engineers want to learn this way.
More scenarios, more blocks, more chaos. A pro tier with advanced failures. Certificates. Institution dashboards. The roadmap is long, and we're just getting started.
