Breakscale

Breakscale lets you put load balancers, caches, databases, queues and 29 other components on a canvas, wire them into a system, and drag the traffic up until something gives. What you see while it happens is a real discrete-event simulation: latency percentiles climbing, queues filling, circuit breakers tripping, and whole systems collapsing into retry storms, all measured from individual simulated requests rather than drawn to look plausible. It runs in your browser, inside VS Code, and inside your AI assistant, which can read your code, draw your architecture, and tell you where it breaks. Most system design material is static diagrams and rules of thumb. "Add a cache." "Use a queue." That makes it hard to build any intuition for why p99 latency falls off a cliff once utilisation passes 80 percent, or how a short timeout with a couple of retries turns one slow database into a total outage. Breakscale is the open-source project xevrion/breakscale (https://github.com/xevrion/breakscale) by xevrion, released under MIT. Ion packages it unmodified from commit d2c876e0e17e, adding only a manifest, an icon and a storage compatibility script.
