The React Native Performance Gap

Traditional Android tools detect frozen frames but can't tell you which React component caused them

❌ Traditional Tools

Standard profilers detect frozen frames and provide stack traces, but they only point to native rendering code—not your JavaScript components.

Stack traces are useless

✅ With De-frost

De-frost tracks React component state changes (commits) and correlates them with native frame rendering—bridging the JavaScript ↔ Native gap.

🎯 Pro Tip: Look for bars crossing the red threshold line—those are frozen frames! The chart breaks down each frame by rendering stage (animations, draw, GPU, etc.) so you know exactly where to optimize.
