pymiro

Signal-native, declarative GUI framework for Python.

pymiro is a modern GUI framework for Python that brings web-like declarative syntax and fine-grained reactivity to the desktop. Inspired by SolidJS, it uses a signal-based reactivity engine and a keyed virtual DOM to efficiently update Qt widgets (PySide6) without relying on heavy class hierarchies or complex event bindings.

Features

• Declarative: Define your UI as a tree of components, just like HTML or React.
• Reactive Signals: State changes automatically trigger surgical updates to only the parts of the UI that depend on that state.
• Component Model: Build reusable, composable pieces of UI.
• Powered by Qt: Uses PySide6 under the hood for native, performant desktop widgets.

Installation

pip install pymiro
