React Native DevTools are powerful, but they still lack one crucial piece: extensibility. At React Universe Conf 2025, Szymon Chmal (Senior Software Engineer at Callstack) introduces Rozenite: a framework designed to bring a robust plugin system back to React Native DevTools. Built on top of the existing architecture, Rozenite makes it possible to extend DevTools without forking or hacks.

• Why Flipper’s plugin system mattered and how its absence in DevTools creates a gap for developers
• How Rozenite hooks cleanly into DevTools communication without breaking stability
• Building plugins with sandboxed execution and React-based UIs inside DevTools
• Official plugins available today: Redux DevTools, TanStack Query, network activity monitoring, performance marks, and more
• How you can build your own plugins for state machines, analytics, feature flags, or any internal app logic
• What’s next: Rozenite 1.0 and a growing ecosystem of community-driven plugins

Whether you need better debugging tools for your own app or want to share plugins with the React Native community, Rozenite makes DevTools truly extensible again.
