Flet 1.0 – Build cross-platform apps in Python

Python needs to be in less places not more.

I believe Python has done more harm than good to the industry.

Its by nature very inefficient, it leads you in the direction to some very poor abstractions (inheritance, monkey patching, mixins etc) and as a result code that is very prone to subtle bugs and issues.

It deserves all the love it gets as an approachable language, but it deserves a lot more flack for everything else.

Using a to-do list app as the first example to advertise a new app framework is absolutely wild in Q3 2026.

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.

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

Interesting, looks like this is a framework built on Flutter.

Loving it. Been using in projects for a while now.

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?

kivy, which does the same thing, has been around for over 10 years. I built my thesis in it a few years ago. not recommended—too many limitations and build issues in practice. given that this one is less mature...I'm not optimistic.

Looks really interesting, but I notice that Bluetooth isn't in the supported services.

Sort of limits how useful it would be for me - Bluetooth is one of the only reasons I'd do a native app instead of PWA.

Please no, python should be deprecated at this age, especially in the era of llm, horrible language from the performance to the dependencies to everything, can’t believe it got popular over perl back in the day
