About Reactotron

Reactotron is a desktop debugger for React and React Native projects, made by the consultancy Infinite Red. You add a small client library to your app as a development dependency, run the Reactotron desktop app, and it shows a live timeline of what the app is doing: API requests and responses, log messages, errors with source-mapped stack traces, Redux or MobX-State-Tree actions and state changes, and AsyncStorage contents. You can also dispatch actions, restore saved state snapshots and overlay design images on a running React Native screen. It is free and MIT-licensed, runs on macOS, Windows and Linux, and has a plugin system plus an MCP server so AI coding agents can read its data. Compared with React Native DevTools it focuses on app state and a running event log rather than breakpoints and profiling, and compared with an intercepting proxy like Proxyman it only sees traffic from apps you've instrumented.

Best for: React Native developers who want a live log of network calls, state changes and errors.

What works

Free and MIT-licensed
Shows network calls, logs and Redux/MST state in one timeline
Dev-only dependency, so production builds are unaffected
Plugin system and an MCP server for AI coding agents

Why people leave

Needs code added to your app before it can see anything
No breakpoints or step debugging; pair it with React Native DevTools
Only sees traffic from the instrumented app, unlike a system proxy
