What problem does it solve?

Castella provides a pure-Python UI framework to create desktop, web, and terminal applications from a single codebase, combining declarative widgets, reactive state, and theming.

Core Features & Use Cases

  • Declarative widgets for UI composition
  • Reactive state management with attachable states and data binding
  • Cross-platform rendering for desktop (GLFW/SDL2), web (PyScript/Pyodide), and terminal (prompt-toolkit)
  • Built-in animation, theming and design tokens, and rich text/markdown rendering
  • Examples and guidance to rapidly prototype apps

Quick Start

Run a simple example to see Castella in action, for example by executing scripts/counter.py.
