Flet 1.0 Released: Build Production-Ready Web, Desktop, and Mobile Apps in Pure Python

Flet 1.0 has reached a stable production release, enabling developers to build cross-platform web, desktop, and mobile applications using Python alone — no JavaScript, Dart, or native mobile SDKs required. The framework is built on Flutter under the hood, giving Python developers access to a rich, performant widget system without leaving the Python ecosystem. For AI engineers who routinely prototype in Python, Flet 1.0 significantly lowers the barrier to shipping polished, multi-platform interfaces for AI-powered tools and demos without switching languages or frameworks. The 1.0 milestone signals API stability, making it viable for production use cases beyond quick prototypes. Developers building internal AI tooling, LLM front-ends, or agent dashboards in Python should evaluate Flet as an alternative to Gradio, Streamlit, or Electron-based approaches.
