Kivy

Kivy is an open-source Python framework for developing GUI apps that work cross-platform, including desktop, mobile and embedded platforms.

The aim is to allow for quick and easy interaction design and rapid prototyping whilst making your code reusable and deployable: Innovative user interfaces made easy.

Kivy is written in Python and Cython and is built on OpenGL ES 2.0. It supports various input devices and has an extensive (and extensible) widget library. With the same codebase, you can target Windows, macOS, Linux (including Raspberry Pi OS), 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.

Installation, Documentation and Examples

Extensive installation instructions as well as tutorials and general documentation, including an API reference, can be found at https://www.kivy.org/docs. A PDF version is also available.

Kivy ships with many examples which can be found in the examples folder.
