Open source UI framework written in Python, running on Windows, Linux, macOS, Android and iOS


Innovative user interfaces made easy.

Kivy is an open source, cross-platform Python
framework for the development of applications that make use of innovative,
multi-touch user interfaces.
The aim is to allow for quick and easy interaction design and rapid prototyping
whilst making your code reusable and deployable.

Kivy is written in Python and Cython, based on OpenGL ES
2, supports various input devices and has an extensive widget library. With the
same codebase, you can target Windows, OS X, Linux, Android and iOS. All Kivy
widgets are built with multitouch support.

Kivy is MIT licensed, actively developed by a great community and is supported
by many projects managed by the Kivy Organization.
