Architecture

Pytron-kit is built on a modular architecture designed for security, high-performance IPC, and developer simplicity. It avoids the "Local Server" overhead by using a direct native bridge, which ensures zero port conflicts and a smaller security surface area.

The Polyglot Stack

Pytron-kit is a polyglot framework that leverages the best tools for each layer:

• Python: The core of the framework (90%+). Handles the CLI, window management, and business logic.
• JavaScript / TypeScript: Powers the frontend bridge (pytron-client), UI components (pytron-ui), and template scaffolding.
• Rust: Provides the high-security "Agentic Shield" bootloader and payload encryption layer.
• C / C++: Low-level OS integration (Win32, GTK, Cocoa), Android JNI bridge, and Nuitka-compiled machine code.
• Kotlin / Java: Android-specific lifecycle management and native platform hooks.
• HTML / CSS: The backbone of all user interfaces and frontend layouts.

Direct Native Communication

Most "Python-as-UI" frameworks spin up a local HTTP server (Flask/FastAPI) and talk via network ports. Pytron-kit uses a direct native bridge. This means zero latency, zero open ports, and zero firewall issues.

from pytron import App
app = App() 
app.run()

Encapsulated State Sync

Pytron-kit implements a reactive system. When you update data in Python, it's automatically diffed and pushed across the native bridge to the Pytron Client, which triggers a re-render in your UI.
