Reflex

Reflex is a framework that helps you create web applications entirely in Python. You write your frontend and backend code in the same language, and Reflex handles the rest. Under the surface, it converts your Python code into a Next.js frontend and FastAPI backend, using websockets to keep everything connected in real time.

The tool includes over 60 ready-to-use components for building user interfaces without writing HTML or CSS. You can create anything from simple data dashboards to complex multi-page applications. Reflex also features an AI Builder that can generate complete applications from plain English descriptions. The framework is open source, meaning you can inspect the code, contribute improvements, and use it without restrictions.

Getting started with Reflex is straightforward. Here are the steps to build your first app:

• Install Reflex using pip by running the command in your terminal. Python version 3.8 or higher is required.

• Create a new project using the initialization command, which sets up a template application in your chosen directory.

• Define your app structure in Python files. You create components for the user interface and state classes to manage data and logic.

• Run your app locally to see changes instantly. Reflex includes hot reload, so edits appear immediately in your browser.

• Use the AI Builder if you want to generate an app from a description instead of coding from scratch.

• Deploy your finished app with a single command to Reflex Cloud, or host it yourself on platforms like AWS, Azure, or Google Cloud.
