Nodezator is a multi-purpose node editor for the Python programming language. It takes your functions (or other callables) and turns them into Python nodes, allowing you to create and execute complex node layouts and even export them back as Python code.

A graph node engine and editor written in Javascript similar to PD or UDK Blueprints, comes with its own editor in HTML5 Canvas2D. The engine can run client side or server side using Node. It allows to export graphs as JSONs to be included in applications independently.
