Python to Mobile - Write mobile apps in pure Python with DSL

Python2Mobile (P2M)

Write mobile apps in pure Python with a declarative DSL. P2M generates or runs native/hybrid apps for Android, iOS, and Web.

Features

• Python DSL - Write UI and logic in familiar Python syntax
• Tailwind-like Styling - Use CSS class names for mobile styling
• Hot Reload - See changes instantly during development
• Multi-LLM Support - OpenAI, Claude, Ollama, or any OpenAI-compatible API
• Multiple Targets - Generate React Native or Flutter code
• DevServer - Preview apps in browser before building

Quick Start

pip install python2mobile

# Create a new app
p2m new myapp
cd myapp

# Run in development mode (hot reload)
p2m run

# Build for production
p2m build --target android
p2m build --target ios
p2m build --target web

Example App

from p2m.core import Render
from p2m.ui import Container, Text, Button

def click_button():
    print("Button clicked!")

def create_view():
    container = Container(class_="bg-gray-100 min-h-screen flex items-center justify-center")
    inner = Container(class_="text-center space-y-6 p-8 bg-white rounded-2xl shadow-lg")
    
    text = Text("Welcome to P2M", class_="text-gray-800 text-2xl font-bold")
    button = Button(
        "Click Me",
        class_="bg-blue-600 text-white font-semibold py-3 px-8 rounded-xl hover:bg-blue-700",
        on_click=click_button
    )
    
    inner.add(text).add(button)
    container.add(inner)
    return container.build()

def main():
    Render.execute(create_view)

if __name__ == "__main__":
    main()

Configuration

Create a p2m.toml file:

[project]
name = "MyApp"
version = "0.1.0"
entry = "main.py"

[build]
target = ["android", "ios", "web"]
generator = "flutter"  # or "react-native"
llm_provider = "openai"  # openai | anthropic | ollama | openai-compatible
llm_model = "gpt-4o"
output_dir = "./build"
cache = true

[devserver]
port = 3000
hot_reload = true
mobile_frame = true

[style]
system = "tailwind"

LLM Configuration

OpenAI

[llm.openai]
api_key = "sk-..."
model = "gpt-4o"

Claude (Anthropic)

[llm.anthropic]
api_key = "sk-ant-..."
model = "claude-3-opus-20240229"

Ollama (Local)

[llm.ollama]
base_url = "http://localhost:11434"
model = "llama2"

OpenAI Compatible

[llm.custom]
base_url = "https://api.example.com/v1"
api_key = "your-api-key"
model = "your-model-name"
x_api_key = "optional-header"
