Latency Metrics
Connect APIs, queues, and databases with precise relationship mapping. Define throughput, payload sizes, and read/write ratios.
Identify bottlenecks before you build. Our engine calculates multi-region data transfer and operational costs at high-scale.
Get instant feedback on single points of failure, data consistency risks, and over-engineering tendencies.
Select from high-scale distributed systems like Uber-lite, global chat, or high-throughput payment gateways.
Drag-and-drop components, map data flows, and run the simulator to see latency metrics and cost estimates.
Analyze AI feedback and refine your architecture. Watch how your scores change as you resolve bottlenecks.

Potential Over-engineering
Kubernetes for a simple worker tier might be excessive; consider Serverless if load is bursty.
Consistency Risk
Your Redis cache layer lacks a TTL strategy for the Auth tokens, leading to staleness.
Stop guessing if your design scales. Our model is trained on thousands of staff-level design documents and real-world post-mortems.
Complex systems designed for senior and staff engineer candidates.
Solve for consistency, global latency, and edge compute for 10M+ DAU.
Implement exactly-once processing and distributed transactions.
Handle heavy throughput, transcoding, and content delivery strategies.
Design a robust pub/sub model for multi-channel messaging.
