## What it is
Ryven is a Qt-based visual node editor and framework for flow-based visual scripting in Python, letting users build dataflow graphs from custom nodes that execute arbitrary Python code. It includes a headless mode for running graphs without the GUI and is built on the ryvencore backend library.

## Use cases
- build dataflow graphs visually in python
- create custom nodes that run python code
- prototype data processing pipelines with a node editor
- run visual scripting graphs headlessly without a gui
- explore flow-based programming in python
- integrate a node editor into another python application

## When to choose
- you want a flexible, hackable node editor for python-based dataflow scripting
- you need a headless mode to execute graphs without a gui
- you want to develop your own node packages on a simple framework
- you prefer diagram-like dataflow representations over plain source code

## When to avoid
- you need a professionally supported, actively developed tool - the maintainer has limited time and updates are minimal
- you want to learn conventional python programming - this is not a teaching tool
- you expect automatic graph generation from existing code
- you need stable built-in example nodes to depend on in production
