Could you build this?
Partial The UI and architecture diagramming are buildable, but a credible simulator of load, failure, and p99 latency with cost estimates requires a validated performance model that vibe coding will not produce.
What it would actually take: Build a discrete-event simulation engine (in Python, Go, or Rust) where components have queueing models, capacity limits, and failure injection. Calibrate per-component latency and cost against real cloud pricing and benchmark data. The hard parts are the accuracy of the queueing and failure models and keeping cost estimates current. This needs distributed-systems and performance-engineering expertise.
