Interactive System Design Simulator

Practice System Design Interviews on an Interactive Architecture Canvas

Practice an architecture problem on PrepVisor's interactive system design canvas. Add and connect system components, reason about QPS and storage capacity, inspect single points of failure, and use the resulting feedback to revisit your design choices. You can work through the architecture as a visual model.

1. Infinite Drag-and-Drop Cloud Topology

Position load balancers, reverse proxies, microservices, caches, and relational or NoSQL datastores with gRPC, REST, and TCP protocols.

2. Real-Time Capacity & Scale Calculations

Compute Read/Write QPS, 5-Year persistent storage, 80/20 Pareto caching RAM, and network bandwidth saturation in real time.

3. Automated Single Point of Failure (SPOF) Analysis

AI Principal Architect inspects directional topology graphs to identify un-replicated databases and missing circuit breakers.
