Flet is a cross-platform framework that enables developers to build interactive desktop, mobile, and web applications using only Python. By utilizing a declarative programming model, it allows for the construction of complex user interfaces through a hierarchical structure of components, removing the need for specialized knowledge of web-specific languages like HTML, CSS, or JavaScript.
The framework distinguishes itself by offloading visual rendering to a high-performance graphics engine while maintaining application logic within a centralized server-side environment. This architecture synchronizes state and user interactions between the interface and the backend through a persistent connection, ensuring consistent behavior across different operating systems.
The platform provides a comprehensive suite of tools for the entire software lifecycle, including native hardware access, automated build pipelines, and the ability to package applications into standalone executables. It supports flexible layout management, custom component creation, and integration with third-party identity providers, allowing for the development of feature-rich applications that function natively on desktop or within a web browser.
