## What it is
Flipper is a desktop debugging platform for mobile developers, providing a visual interface to inspect, visualize, and control iOS, Android, and JavaScript apps. It is extensible via a plugin API and supports SDKs for Android, iOS, React Native, and JS.

## Use cases
- inspect network traffic from an iOS app during development
- debug layout of an Android app from a desktop UI
- debug a React Native app with Hermes and React DevTools plugins
- inspect and edit SharedPreferences or UserDefaults on a device
- view logs and crash reports from a mobile app in one place
- build custom debugging plugins for my mobile app

## When to choose
- you need a visual, plugin-based debugger for native iOS or Android apps
- you are maintaining an older React Native project and can use v0.239.0
- you want to build custom in-app debugging tooling on an extensible platform

## When to avoid
- you are starting a new React Native project - React Native support ended at v0.239.0 and Meta is building dedicated tooling
- you need actively maintained software - the repository was archived in September 2025 and is read-only
- you want a lightweight CLI-only debugger rather than a GUI platform
