## What it is
Writer Framework is an open-source Python framework for building data and AI applications with a drag-and-drop visual editor for the frontend and plain Python event handlers for the backend. It synchronizes UI and state in real time over WebSockets and stores UI definitions as version-controllable JSON.

## Use cases
- build a data dashboard with a visual editor and Python backend
- create an AI chat app powered by an LLM
- quickly prototype internal tools with drag-and-drop UI
- visualize and analyze data with an LLM
- build a web app without writing HTML, CSS, or JavaScript
- connect external APIs to a custom UI with Python event handlers

## When to choose
- you want a Python-only backend with a no-code visual frontend
- you need fast, testable event handlers and real-time state sync
- you're building data apps or AI apps with complex custom logic
- you want UI definitions stored as JSON for version control

## When to avoid
- you need pixel-perfect custom frontend design or a custom JS stack
- you're building a large traditional SPA with React/Vue
- you need Python 3.13 support
- you want a fully code-defined UI without a visual editor
