Flet – multi-platform apps in Python powered by Flutter

Flet is a framework that allows developers to create real-time web, mobile, and desktop applications using Python without the need for frontend experience. It simplifies the development process by enabling users to build interactive apps quickly, ranging from internal tools to high-fidelity prototypes. Flet's architecture eliminates the need for complex setups involving JavaScript frontend, REST API backend, and databases, offering a monolith stateful app in Python for multi-user, real-time Single-Page Applications. The framework comes with a built-in web server, assets hosting, and desktop clients, requiring no additional SDKs or dependencies. Flet leverages Flutter for its UI, ensuring a professional look across different platforms. It supports multiple programming languages, with Python currently available and plans to include Go, C#, and others in the future. Developers can deploy Flet applications as web apps, standalone desktop apps for Windows, macOS, and Linux, or as Progressive Web Apps (PWAs) on mobile devices, including iOS and Android.

The analysis critiques Copilots, chatbots, and React for web development, citing slow sites, complex code, and high costs. It advocates for a shift to browser APIs, CSS, and HTML for better performance and lower expenses. Transition challenges include finding developers skilled in vanilla JavaScript. Organizations are urged to prioritize simplicity, efficiency, and core web technology training.

For every sufficiently successful single-language ecosystem, there will be people trying to use a different language, turning it into a multi-language ecosystem.

Also, for every sufficiently successful multi-language ecosystem, there will be people trying to get it to support one more language.

Why though? Flutter was built for Dart and, while not my favourite language, it does that job very well. When the major drawback of all multi-platform frameworks tends to be performance, how does using a much slower, non-compiled language improve things?

I have some confusion how a dynamically typed interpreted language that allows nulls interfaces with something that expects types, null safety, and ultimately is compiled.

“View via iOS Flet app” is not “enables developers to easily build realtime web, _mobile_ and desktop apps in Python.”

All these multi-platform kits are getting fatiguing. Electron, sciter, neutralino, proton native...there are hundreds of others, and now Flet. Reminds me of the Google/Apple app stores, where there are 100+ solutions for the same problem, and all of them suck.

I wonder if we really did a good thing by building this "app culture" where everything needs a little "app" as a way of extracting a little more money from people. Although "app" means application, the word "app" is apt because it signifies the commercialization of applications into advertisements-as-a-program, in the same way that YouTube transformed videos into advertisements-as-a-video.

What a mess.
