Simulating real system behavior from an architecture diagram

Some enthusiast vibe-coded a simulator that lets you test how your architecture would behave in real life.

– You can set and control a budget
– Adjust load on the fly
– Visually build your architecture diagram
– Configure sharding and replication
– Run chaos testing (random failures, spikes, network latency)
– Share diagrams and scenarios with others

Great for learning, no doubt.

For real-world validation though, I felt a couple of gaps:
– No clear understanding of how load maps to component parameters. Right now it’s a black box.
– No integration with external systems.

It would be great if you could feed the product a JSON diagram with components and connections and have it automatically validate the setup against requirements.
Of course, you still can’t avoid testing on a real environment. But it’s slow and expensive. A tool like this could give you fast, cheap feedback upfront.

Enjoy.
