Design, simulate, and stress-test system architectures
Entsemble is a playground for system design — build it, load-test it, break it on purpose, and learn what actually happens before it happens in production.
Drag-and-drop architecture
AWS, GCP, and Azure components, wired together with typed connections — sync calls, queues, streams, cache and DB reads.
Simulate before you build
Push real traffic through your design, watch latency and error rate live, and see exactly where it bottlenecks.
Chaos-test it
Kill a node, throttle bandwidth, spike CPU — ten fault types you can throw at any component or connection on demand.
An AI that can see your canvas
In the workspace tier, talk or type to an agent that understands your design and can add components for you.
Free to use. No AI required.
Every tool is free and open — the workspace tier just adds an AI that can see and edit your work alongside you.
