Welcome to Flexx’s documentation!

Flexx is a pure Python toolkit for creating graphical user interfaces (GUI’s), that uses web technology for its rendering. Apps are written purely in Python; The PScript transpiler generates the necessary JavaScript on the fly.

You can use Flexx to create (cross platform) desktop applications, web applications, and export an app to a standalone HTML document. It also works in the Jupyter notebook.

The docs are on Readthedocs, the code is on Github, and there is a demo server. Once you’ve got started, the most important page is probably the Widget reference.
