A design canvas that actually checks your work.
Design Canvas
Build real systems, not diagrams
Drag load balancers, application servers, databases, caches, queues, and CDNs onto a canvas and wire them together; every component has the real config fields an actual system has (instance size, routing algorithm, replication, TTLs), not a generic box with a label on it.
Simulation Engine
Real capacity math, not guesses
Every submission runs against an actual capacity, latency, and cost simulator; not a checklist. It tells you exactly which server is overloaded at the current traffic split, what your p95 looks like, and whether you're over budget, the same way a real design review would.
