Flet enables developers to easily build realtime web, mobile and desktop apps in Python. No frontend experience required
### 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, real-time 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 a built-in web server with assets hosting and desktop clients. ### Powered by Flutter Flet UI is built with [Flutter](https://flutter.dev/), so your app looks professional and could be delivered to any platform. Flet simplifies the Flutter model by combining smaller "widgets" to ready-to-use "controls" with an imperative programming model. ### Speaks your language Flet is language-agnostic, so anyone on your team could develop Flet apps in their favorite language. [Python](https://flet.dev/docs/guides/python/getting-started) is already supported, Go, C# and others are [coming next](https://flet.dev/roadmap). ### 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](https://web.dev/what-are-pwas/) or view via Flet app for iOS and Android. ## Running locally for development - Install dependencies `pip install -r requirements.txt` - Start the flet development server `flet main.py` This will open a new window and any changes made to main.py will be automatically reflected ## What makes this work on Railway? - **Custom build plan:** [nixpacks.toml](https://github.com/brody192/reflex-template/blob/main/nixpacks.toml) - Sets the environment variable `GIN_MODE` to `release` for production purposes - Installs two needed system libraries `libgtk-3-0` and `libgstreamer1.0-0` - Have Flet listen on `$PORT` - Setting `port` to `int(os.getenv("PORT", 8502))` in the `ft.app` constructor, This allows Railway to properly route traffic to and from the Flet app ## Similar templates - [open-excalidraw](https://railway.com/deploy/open-excalidraw) — Self-hostable collaborative drawing built on Excalidraw - [Next.js + Prisma + PostgreSQL Starter](https://railway.com/deploy/nextjs-prisma-postgres) — Deploy a Next.js app with Prisma ORM and PostgreSQL in one click. - [caring-vibrancy](https://railway.com/deploy/caring-vibrancy) — Deploy and Host caring-vibrancy with Railway Open this page in a browser: https://railway.com/deploy/gIcMS9
