Breakscale: Build a system, load it until it breaks, and watch why (1.3k stars)
What it does
All text below is quoted directly from the project README.
>A system design simulator where every number is measured. Build a system, load it until it breaks, and watch why.
>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.
>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.
Features:
- 33 components. Load balancers, caches, databases, queues and workers, plus CDNs, rate limiters, circuit breakers, read replicas, shards, autoscalers, stream brokers, WebSocket gateways, serverless functions, bulkheads and more.
- 23 worked examples. Sixteen teaching scenarios that each isolate one failure mode, and seven reconstructions of real architectures.
- A real discrete-event engine. Finite server slots, gamma-distributed service times and measured percentiles, with no formula standing in for the simulation.
- Chaos controls. Crash a node, slow it down, force an error rate, or cut a single link, then watch the failure travel.
- Deterministic runs. The same seed and topology replay identically, every time.
- Explanations built in. Every metric and unit has a plain-language definition one hover away.
- Share links and design files. Send a design as an encrypted link, or save it as a .breakscale file that opens on the website and in VS Code.
- Private by design. No account, and your designs never leave your machine unless you share them.
>Breakscale is also an MCP server, so Claude, Copilot, Cursor, Codex and other assistants can use it for you.

@krexillo already did, i have a bigger project xevrion/breakscale
@codersGyan @Ashutosh_7x7 @xevrion_the1 Bhai free access Dena fir we will have a look and say if this is built from scratch 😇 or you just git clone xevrion/breakscale
