Kivy - Open source Python library for rapid development of applications
that make use of innovative user interfaces, such as multi-touch apps.
Kivy runs on Linux, Windows, OS X, Android and iOS. You can run the same code on all supported platforms.
It can use natively most inputs, protocols and devices including WM_Touch, WM_Pen, Mac OS X Trackpad and Magic Mouse, Mtdev, Linux Kernel HID, TUIO. A multi-touch mouse simulator is included.
Kivy is 100% free to use, under an MIT license (starting from 1.7.2) and LGPL 3 for the previous versions. The toolkit is professionally developed, backed and used. You can use it in a commercial product.
The framework is stable and has a well documented API, plus a programming guide to help you get started.
The graphics engine is built over OpenGL ES 2, using a modern and fast graphics pipeline.
The toolkit comes with more than 20 widgets, all highly extensible. Many parts are written in C using Cython, and tested with regression tests.

See how easy it is to create a simple Hello World application that just shows an actionable button:
from kivy.app import App from kivy.uix.button import Button class TestApp(App): def build(self): return Button(text='Hello World') TestApp().run()

- Special thanks to
- Mark Hembrow, who is one of our first sponsor, by giving us a Mac Mini. Which is currently used for all the build system: unit test on Windows / MacOSX and Ubuntu + building the HTML and PDF documentation.
- Christopher Denter (dennda) who was a core-developer in the first stage of the project. He contributed a lot by improving the documentation, implementing the Kivy extension system, pep8 hook and fixes, spelling provider. He also did 1 GSOC on the previous PyMT framework on implementing a virtual keyboard with a better navigation.
- Edwin Marshall (aspidites) helped with quality and documentation, as well as adding a few features.
- Vincent Autin for his work as a designer for the project, specially on the logo !
Many people have contributed to Kivy and we're always interested in growing our community. If you want to help in terms of writing code, improving documentation, testing, etc. or simply making a donation, please do not hesitate to contact us!
