## What it is
Kivy is an open-source Python UI framework for building cross-platform GUI applications from a single codebase. It is built on OpenGL ES 2.0 with a Cython core, ships an extensive multitouch-enabled widget library, and targets Windows, macOS, Linux (including Raspberry Pi), Android, and iOS.

## Use cases
- build a cross-platform desktop app in python
- develop an android app with python
- write an ios app using python
- create a multitouch gui application
- rapidly prototype a user interface in python
- deploy one python codebase to windows mac linux and mobile
- build a kiosk or raspberry pi touch interface

## When to choose
- you want one python codebase running on desktop and mobile platforms
- your app needs multitouch or custom-drawn, non-native UIs
- you need rapid prototyping of innovative interfaces with an extensible widget library
- you want a permissive MIT license for commercial apps

## When to avoid
- you need native-looking platform widgets and OS-native UX conventions
- you are building a web application rather than a native app
- you need very small binaries or minimal startup overhead on constrained hardware
- your team prefers declarative web-style UI stacks over the Kv language
