Flet 1.0 has arrived, enabling developers to create web, desktop, and mobile apps from a single Python codebase without any frontend experience. The framework offers over 150 controls and services, supports popular Python libraries like NumPy and pandas on mobile, and includes packaging tools for app stores. It also provides a web-based Studio for instant experimentation and integrates with AI assistants via Flet MCP.

I built a few Kivy apps years ago at an old job. It was a little clunky, but it got the job done. Haven’t heard of this framework yet, I wonder how compares in developer experience? Anyone have any experience with it?
The problem is I don’t want to use Python for everything that bad. If I’m going to reach for a cross platform toolkit these days, I’m personally going to reach for Tauri. Could be useful if you’re really married to Python I suppose.

Is there a downloadable sample somewhere? Would like to see how large a native build is.

Choosing to build an application around a framework whose top contributors are Claude and Copilot may have catastrophic consequences for your project, especially if it's a business.

Is this build on top of flutter?
And for web, does it generate plain HTML/CSS, the DOM tree, or just generate everything in a canvas?
