"I ended up using this in a couple of planning meetings. The live latency view made the tradeoffs easier to talk through without turning it into a whiteboard debate."

FIELD REPORTS
What engineers actually say
Used by engineers and students to prep, teach, and stress‑test distributed architectures.
"I used it while reviewing front-end flows before implementation and it was actually helpful. The visual states made it obvious where the UI needed clearer loading, error, and empty-state handling instead of guessing."
Nitin Chaudhary

"I used this for gaining a deeper understanding of how the systems I work with handle traffic at different volumes. The visual feedback makes it very easy to identify weak points. It speeds up the iteration and ideation processes."

"The templates are better than I expected. I could start from something close to what we run and then tweak it instead of dragging everything out from scratch."

"I used it for interview prep because it made system design feel less abstract. Seeing requests move through the architecture helped me explain tradeoffs out loud instead of memorising diagrams."

"We covered these ideas in our distributed systems module, but this made the behavior easier to see. Queues, failures, and latency changes were much easier to connect to the theory."

From the builder
"I built it because architecture diagrams should do more than sit there looking confident. The fun starts when your system pushes back with latency, failures, and cost before production gets a vote."
