Everything You Need to Simulate

From building to breaking — a complete toolkit for distributed systems design.

Drag-and-Drop Builder

Visually compose distributed systems by dragging load balancers, servers, databases, and queues onto an infinite canvas.

Real-time Traffic Simulation

Send simulated traffic through your architecture and watch requests flow, queue up, and hit bottlenecks live.

Observability Dashboards

Built-in metrics for latency, throughput, error rates, and resource utilization across every component.

Failure Injection

Chaos-test your designs by killing nodes, adding latency, or saturating queues to discover weak points.
