# How To Build a Plugin Framework by Hacking React Native DevTools

Szymon Chmal explains how he built Rozenite, a plugin framework for React Native DevTools, and shows what developers can create with it.

What if React Native DevTools could support custom plugins?

That question led Szymon Chmal to build Rozenite. He dug into how DevTools work, reverse-engineered their architecture, and found a way to add functionality without forking them.

In this talk, Szymon explains why he built Rozenite and how it connects to DevTools. He’ll show how to build custom panels with React UIs, communicate with the app, and run plugin code safely—then explore what developers can do with an extensible React Native DevTools.
