Breakscale
Claude connectorCommunityBuild a system design, load it until it breaks, and see why, on a live simulator right in the chat.
Breakscale is a system design simulator. Ask Claude to design an architecture, or to turn your codebase into one, and it builds the design on a live Breakscale canvas and runs it through a real discrete-event simulation. Requests queue, services saturate, retries pile up, and every number on the canvas is measured from simulated requests rather than estimated.
Claude gets the same numbers back: throughput, p50, p95 and p99 latency, error rates, and which component is the bottleneck. So it can tell you where your design breaks and change it. You can drag the traffic up, move components around, or open the canvas full screen, and your edits go back to Claude, so its next change starts from what you are looking at. Every design also comes with a breakscale.tech link that opens it in the browser.
There are 33 components to build with, including load balancers, caches, databases, queues and workers, rate limiters, circuit breakers, read replicas, shards, autoscalers, stream brokers and WebSocket gateways.
No account or sign-in is needed. Designs are simulated in memory and are not stored.
