Pyplet¶

Python everywhere¶

Serve interactive web applications entirely in Python. Pyplet couples a Tornado backend with a Pyodide-powered (via PyScript) client runtime, so you can write browser code, DOM manipulation, plotting, and real‑time messaging without leaving Python.

Resources¶

• Pyplet sources
• Pyplet on PyPI
• Pyplet examples
• Pyplet Apache 2 license

Key capabilities:

• Pure Python on both sides: Tornado on the server, Pyodide in the browser
• Simple micro app structure and packaging model
• WebSockets for real-time, async interactions
• Works with scientific Python packages in the browser (e.g., NumPy, Matplotlib)

Get started in minutes:

# Create a virtual environment (Python 3.12+)
uv venv --python 3.12
source .venv/bin/activate

# Install Pyplet
pip install pyplet

# Create a new micro app
pyplet init my_app

# Run the server and serve apps under ./apps
pyplet start

Then open http://127.0.0.1:8080 to browse available apps.

Next steps:

• Follow Getting Started to configure assets and explore the example apps
• See Examples to clone the examples repo and tour the available micro-apps
• See Micro Apps for app structure and packaging details
• Try the Tutorials (Frontend-only, WebSocket) to build your first apps end to end
• Browse the API Reference for the DOM DSL, client bootstrap, and server internals
