To write a Flet app you don't need to be a front-end guru, but it's recommended to have a basic knowledge of Python and object-oriented programming.
In this guide we'll study the structure of a Flet app, learn how to output data using Flet controls, request data from a user and build basic page layouts. We will also cover some packaging and deployment options to deliver a ready app to your users.
From idea to app in minutes
An internal tool or a dashboard for your team, weekend project, data entry form, kiosk app or high-fidelity prototype - Flet is an ideal framework to quickly hack great-looking interactive apps to serve a group of users.
Simple architecture
No more complex architecture with JavaScript frontend, REST API backend, database, cache, etc. With Flet you just write a monolith stateful app in Python only and get multi-user, realtime Single-Page Application (SPA).
Batteries included
To start developing with Flet, you just need your favorite IDE or text editor. No SDKs, no thousands of dependencies, no complex tooling - Flet has built-in web server with assets hosting and desktop clients.
Powered by Flutter
Flet UI is built with Flutter, so your app looks professional and can be delivered to any platform. Flet simplifies Flutter model by combining smaller "widgets" into ready-to-use "controls" with imperative programming model.
Speaks your language
Flet is language-agnostic, so anyone on your team could develop Flet apps in their favorite language. Python is already supported, Go, C# and others are coming next.
Deliver to any device
Deploy Flet app as a web app and view it in a browser. Package it as a standalone desktop app for Windows, macOS and Linux. Install it on mobile as PWA or view via Flet app for iOS and Android.
