Crucible

Tools Live
Crucible canvas running a microservices template with live per-node metrics

Browser-based system design simulator. Drag a 23-kind component catalog onto a canvas, wire it up, drive 1→1M rps, inject chaos, watch live p50/p99 latency, throughput, queue depth, and error rate per node. Architectures actually run: Go simulation engine compiled to ~200 KB of TinyGo WASM, hosted in a Web Worker, driving a SvelteKit 2 + Svelte 5 (runes) + @xyflow/svelte canvas. No server, no SSR, deployed static to Vercel.
