AppGameKit is a simple cross platform game development tool that runs on Windows, Linux, MacOS and Raspberry Pi. A version to run on Android and iOS is also available. With AppGameKit you can use a simple Basic like programming language to develop cross platform applications, 2D and 3D games and deploy to many platforms such as Windows, Linux, MacOS, iOS, Android, HTML5 and even develop AR and VR applications for desktop and mobile without need to change any of your code. The same code runs everywhere. The best part is, you can preview and run your application on the target device right from the IDE through WiFi with access to all device features such as camera, sensors and touch. It is allow you to test your applications on the target device at any point during development without need to manually compile, export and install it on the device.

You can also use C++ to code your applications to get better performance or implement 3rd party libraries and tools and even add your own features and share it with the community if you want. This is how it become possible to use community made implementations of AppGameKit to code in C#, Python or any other languages. Some of the extra features available today are also developed by 3rd party using the C++ library and offered as a DLC to add even more functionality.
