Performance EngineeringDevTools Hook • 60 FPS

React Perf Profiler — DevTools Extension for React Performance Engineering

Live Site Code

A Chrome and Firefox DevTools extension that hooks directly into __REACT_DEVTOOLS_GLOBAL_HOOK__ to profile React component render behavior at scale — detecting wasted renders with fiber bitmask decoding, quantifying memoization effectiveness, parsing RSC wire payloads, and predicting render times with TensorFlow.js. All heavy analysis is offloaded to three dedicated Web Workers, keeping the DevTools panel at 60fps across component trees with 10,000+ nodes.
