TauPy Framework

TauPy

Build desktop apps with Python + Rust, and drop in React/Vite when you want. Fast reloads, native window controls, and a tiny API surface.

Why TauPy

• Hybrid by design - Python backend + Rust launcher; use Python widgets or a full React front-end.
• Hot dev loop - edit → window refreshes near-instantly, no page reload dance.
• Native window API - minimize/maximize/resize/drag, all routed through Python to the launcher.
• Shipping ready - taupy build bundles your front-end, rebuilds the launcher, and Nuitka-packages the backend.

Code example (Python UI)

from taupy import App, VStack, Text, Button, State
from taupy.events import Click

app = App("Hello TauPy", 800, 500)
msg = State("Hello, TauPy!")

@app.dispatcher.on_click("btn_hello")
async def hello(_: Click):
    msg.set("Button clicked!")

@app.route("/")
def home():
    return VStack(Text(msg), Button("Click me", id="btn_hello"))

if __name__ == "__main__":
    import asyncio
    asyncio.run(app.run(VStack(id="root")))

Quick start (React front-end)

taupy new [app_name]
cd [app_name]
npm install
taupy dev

Build

taupy build

Pipeline:

1. Build React/Vite (if present) → target/dist
2. cargo build --release for the launcher → target/launcher
3. Nuitka bundle backend → target/app.exe

Performance snapshot (indicative)

Scenario	TauPy (Python + Rust)	PyQt / PySide	Tkinter	Electron
Cold start (release build)	~300–600 ms	~900 ms – 1.8 s	~500–900 ms	~1.5 – 3 s
Hot reload (code → UI)	~40–120 ms (WS diff)	Full widget refresh	Full redraw	~200–500 ms
UI update (state → render)	~10–40 ms	QWidget update	Full widget update	Virtual DOM diff
Bundle size	~6–15 MB + dist	40–80 MB	~2–5 MB	120+ MB
UI stack	HTML/CSS (WebView)	Native Qt	Native Tk	Chromium

Measurement conditions

Measurements taken on Windows 11, Ryzen 7 5800X, NVMe SSD.
Release builds, minimal "hello world" applications.
Numbers are indicative and vary by project size and configuration.

TauPy CLI

• taupy dev — run backend + external front-end (Vite) with hot reload.
• taupy build — build front-end, launcher, and Nuitka bundle into target/.
• taupy new <name> — scaffold a new TauPy project.

Dev vs Prod (auto)

• Dev (--dev): external HTTP (Vite 5173), hot reload.
• Prod: serves bundled dist/ on 8000. Override with TAUPY_EXTERNAL_HTTP / TAUPY_HTTP_PORT.

Roadmap

• Cross-platform launcher (Linux/macOS)
• Native dialogs & notifications
• Packaging presets (single-file)
• Built-in icon set & theme presets
• DevTools/inspector mode
• Playground in browser

Requirements

• Windows 64-bit, Python 3.11+
• Rust toolchain (launcher rebuild)
• Node.js (for React/Vite, optional)
