 **Pyrox** is a Python back-end engine and application framework built on **PyQt6**. It provides a rich set of interfaces, models, services, and abstractions for building industrial automation and desktop applications. Pyrox is designed to be used as a foundation — downstream projects like [ControlRox](https://github.com/iroxusux/ControlRox) build their entire application layer on top of it.
