Reactotron

Reactotron is a desktop debugger that connects to React and React Native applications, allowing developers to inspect application state, network traffic, and performance metrics from a graphical interface. It supports features such as viewing and hot‑swapping Redux or mobx‑state‑tree state, tracking global errors with source‑mapped stack traces, logging console‑style messages, and monitoring Async Storage or image overlays in React Native. The tool is packaged as a cross‑platform app for macOS, Linux and Windows and is added to a project only as a development dependency, leaving production builds untouched.

Targeted at developers working on any size of React or React Native codebase, Reactotron provides plugins for common concerns—network requests, benchmarking, saga tracing, and integrations with libraries like apisauce, MMKV, and Storybook. Its open‑source nature and free licensing make it accessible for both individual contributors and larger teams. Installation is handled via downloadable releases, and extensive documentation guides setup, usage, troubleshooting, and contribution.
