Why Python Developers Are Abandoning React for Flet

The last time I had a demo in 36 hours, the AI was working perfectly by midnight. What I needed was a button the client could click. I spent the entire next day fighting CORS between two apps I had written myself — running on the same machine, refusing to talk to each other.

The client looked at it and said: "This looks like something from 2009."

That was the moment I decided to stop paying the JavaScript Tax.

In this video, I break down exactly why Flet — a Python framework powered by Flutter's rendering engine — is changing the game for Python developers building AI applications. No React. No Next.js. No webpack. No CORS. Just Python.

Here's what you'll learn:
- What the "JavaScript Tax" actually costs Python developers in 2026
- Why Flutter's rendering engine gives Flet a structural performance advantage over Streamlit, Gradio, and web-based Python wrappers
- How Flet's state model eliminates the Redux/Zustand/Context API complexity with a single page.update() call
- A complete AI dashboard built LIVE on screen in under 10 minutes (with timer running)
- When Flet is the right choice — and when it's genuinely not
- Why "the interface is the product" changes everything about how you should prioritize your stack

Full code from the live build is below.
