Reactotron

Reactotron is a powerful debugger for React and React Native applications. It provides an easy-to-use interface for developers to monitor their application's state, network requests, and performance metrics and can be used for any size of project, from small personal apps to large-scale enterprise applications. The OG debugger at Infinite Red that we use on a day-to-day basis to build client apps. Additionally, Reactotron is completely open source and free to use, making it an invaluable tool for developers at all levels of experience.

Use Reactotron to:

• view your application state
• show API requests & responses
• perform quick performance benchmarks
• subscribe to parts of your application state
• display messages similar to console.log
• track global errors with source-mapped stack traces including saga stack traces!
• dispatch actions like a government-run mind control experiment
• hot swap your app's state using Redux or mobx-state-tree
• show image overlay in React Native
• track your Async Storage in React Native

You plug it into your app as a dev dependency so it adds nothing to your production builds.
