Interactive canvas to build system topologies and simulate load to watch queues, latency, and bottlenecks
The product is an interactive canvas for building system architectures and running simulated load to observe queues, latency, and failure points before production. It solves sizing and resilience problems for inference rigs and request paths such as gateways, caches, queues, and databases. It is for backend, ML, and platform engineers, developers and operations teams in B2B contexts, including those preparing for system-design interviews. It is delivered as SaaS with a free tier, using a deterministic simulation engine with multiplayer collaboration and side-by-side comparison.
