Rozenite is a plugin-based extension system for React Native DevTools that enables developers to build and install custom debugging panels directly into the standard DevTools interface. It is designed to eliminate context switching by consolidating debugging, inspection, and profiling tools into a single unified window.

The system works by allowing plugins to register panels that are automatically discovered and loaded into React Native DevTools at runtime. These panels can be built using web technologies and interact with the running React Native application through a structured communication layer based on the Chrome DevTools Protocol and supporting runtime bridges.

Rozenite supports both Expo and bare React Native applications and integrates with common bundlers such as Metro and Re.Pack. It provides a plugin ecosystem where developers can install official or third-party tools for tasks like network inspection, state debugging, storage inspection, and performance monitoring.

The architecture includes a runtime layer responsible for plugin orchestration, lifecycle management, and communication between the DevTools frontend and the running app. It also supports development features such as hot reloading of plugins and safe isolation between plugin contexts.

Rozenite is designed to be extensible, allowing teams to create custom internal DevTools tailored to their specific application needs, while still maintaining a consistent DevTools experience.

Key features include:

• Plug-and-play DevTools panels for React Native
• Automatic plugin discovery and runtime loading
• Unified debugging interface inside React Native DevTools
• Support for Expo, bare React Native, Metro, and Re.Pack
• Real-time debugging tools (network, state, storage, performance)
• Extensible plugin architecture for custom panels

Common use cases include:

• Building custom debugging tools for React Native apps
• Inspecting application state and network activity in real time
• Creating internal developer dashboards
• Enhancing team debugging workflows
• Extending React Native DevTools with project-specific functionality

Rozenite is developed by Callstack as an open-source DevTools extension framework for React Native ecosystems.
