## What it is
Pyjs is a Python port of Google Web Toolkit that compiles Python code to JavaScript for building Rich Media AJAX applications in the browser, paired with a desktop widget API similar to PyQT or PyGTK. It also runs the same Python application natively on the desktop via multiple web-engine backends.

## Use cases
- write web apps in python instead of javascript
- compile python code to javascript
- build rich ajax applications in python
- run the same python gui app in browser and on desktop
- port gwt-style development to python

## When to choose
- you want to develop browser applications in Python with a desktop-style widget API
- you need one codebase that runs both in the browser and as a native desktop app
- you prefer a GWT-like compile-to-JS workflow

## When to avoid
- you need a modern, actively developed framework with current browser standards support
- your project targets Python 3 exclusively, since Pyjs is largely Python 2 era
- you want a lightweight SPA toolchain rather than a full compiler and widget set
