Reactotron is a desktop debugging tool for React and React Native applications, available on macOS, Linux, and Windows. You install it as a development dependency in your app, meaning it has no effect on your production builds, and it connects to a separate desktop app where you can inspect what's happening inside your project in real time. With Reactotron, you can watch your application's state change as users interact with it, see all API requests and responses as they happen, display log messages similar to what you'd normally see in a browser console, and track errors with detailed stack traces. It also lets you monitor Async Storage in React Native apps, run quick performance benchmarks, and even hot swap your app's state when using Redux or mobx-state-tree. There's an image overlay feature for React Native as well, letting you visually check your UI against a design. The tool supports plugins for networking, Redux, MST (MobX State Tree), apisauce, React Native MMKV, Storybook, and more. You can also write custom commands to trigger actions inside your app directly from the Reactotron desktop interface. Reactotron is developed and maintained by Infinite Red, with contributions from over 70 community members, and is completely free and open source.
