## What it is
Rio is a pure-Python framework for building websites and apps with React-style components, requiring no HTML, CSS, or JavaScript. Apps can run locally on the desktop or be deployed to the web.

## Use cases
- build web apps in pure python
- create dashboards without javascript
- build crud applications quickly
- make data science apps with a gui
- prototype machine learning demos as web apps
- build internal tools without html css

## When to choose
- you know Python but not web frontend technologies
- you want React-style component architecture in Python
- you need apps that run both locally and on the web
- you're building data apps, dashboards, or internal tools

## When to avoid
- you need fine-grained control over HTML, CSS, or JavaScript
- you're building a large production SPA with complex frontend requirements
- you need a mature ecosystem comparable to React or Vue
- SEO-critical public websites where server-rendered HTML matters
