SysSimulator is a passion project by Ronit Dahiya — a browser-native playground for drawing distributed systems, running a Rust discrete-event simulator compiled to WebAssembly, and layering chaos plus rough AWS cost estimates on top. The UI is built with Flutter Web.
Goal: make system design interview prep and resilience conversations feel tangible — traffic, failures, and metrics on a canvas you can iterate in minutes.
