Cross platform

Kivy runs on Linux, Windows, OS X, Android, iOS, and Raspberry Pi. You can run the same code on all supported platforms.

It can natively use 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.

Business Friendly

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.

GPU Accelerated

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.

Usage example

See how easy it is to create a simple Hello World application that shows an actionable button:

from import App
from kivy.uix.button import Button

class TestApp(App):
    def build(self):
        return Button(text='Hello World')



Result of the example: A window with the text 'hello world' positioned in the middle.
