 ## Build your own plugin
 
 The Flipper desktop app and the mobile native SDK establish a connection which is used to send data to and from the device. Flipper does not make any restrictions on what kind of data is being sent. This enables a lot of different use-cases where you want to better understand what is going inside your app. For example you can visualize the state of local caches, events happening or trigger actions on your app from the desktop.

Learn more on how to [extend Flipper](extending/index.md) and build your own plugin. The native implementations are written in Java, Objective-C, or C++, the desktop UI is written in React.

 In 2015, we introduced [Stetho](http://facebook.github.io/stetho/), an Android debugging bridge built on top of [Chrome DevTools](https://developers.google.com/web/tools/chrome-devtools/). While it was a valuable tool to us and many members of the community, we felt that it limited us in what we could do with it. Stetho is Android-only and while Chrome DevTools gave us a nice foundation to build upon, they also limited us in what we could build. Stetho is an Android tool and Chrome DevTools is built for web developers. This means we can only provide a good experience for the intersection of those two development environments, which was very limiting. With Flipper being built as a standalone app, we can do more things, like handling adb connections and supporting iOS, which wasn't easily achievable with Stetho.

We are committed to continuously improving Flipper with new features and plugins, however, we are aware that not all Stetho features are currently supported by Flipper. If you are using a particular feature of Stetho which isn't supported by Flipper, we are more than happy to hear about your use-case. Stetho will continue to work and we are not abandoning it so you can choose the tool that fits your needs best. We are confident that Flipper will work well for most use-cases and are more than happy to accept contributions from the open-source community adding new features.

 Displaying your data in a table might work for many use-cases. However, depending on your plugin and data it might make sense to customize the way your data is visualized. Flipper uses React to render the plugins and provides a variety of ready-to-use UI components that can be used to build custom plugin UIs.
