Meet Flet 1.0. Build beautiful web, desktop, and mobile apps from one Python codebase. No frontend experience required.

Start with a simple counter: use ready-made controls, arrange them with Python, and connect the button to a Python function that increases the count. Try online in Flet Studio or locally with uv or pip.

Flet offers 150+ controls and services, layouts, navigation, forms, and dialogs. Bring NumPy, pandas, Pillow, and cryptography to mobile with prebuilt packages for iOS and Android. Package your app for desktop, mobile, and web with flet build, ready for the App Store and Google Play.

Run Python in the browser with Pyodide and WebAssembly, or keep code on a server. Write pytest tests and catch visual changes with screenshots. Connect your coding assistant to Flet MCP. Compose custom controls or wrap Flutter packages. Support screen readers and keyboard shortcuts.

Meet Flet Studio: open your browser, pick an example, write Python, or ask the AI agent. Run and share your app. No installation required.
