Qt & QML Live Coding is a viewer app that allows you to develop Felgo apps & games on your desktop, and view the result in real-time on your device, without installing mobile SDKs.

Boost your productivity, by saving time on compilation and deployment.

Felgo Live is available for free with the Felgo SDK. Sign up at the Felgo website to fast forward your app & game development.

Felgo is based on the Qt framework. Qt is a powerful cross-platform toolkit based on C++ which enables powerful animations with Qt Quick and native performance on all major mobile platforms.

Felgo extends the Qt 5 framework with components that you can test with this app. These are for example:
- Components that allow native user experience on all major mobile platforms with a single code base. E.g. on iOS you will experience swipe back gesture support, while on other platforms a navigation drawer is used – this is supported automatically without any change of code.
- Full range of native widgets optimized for a native platform behavior like tabs, dialogs and list views.

Felgo allows native user experience with a single code base and fluid animations.

Huge time saver!

Being able to simultaneously view changes to the app across devices is just a huge advantage. Anyone that has done this the traditional way will immediately feel giddy. Time is money!
