## What it is
Ratchet is a CSS and JavaScript component framework from the Bootstrap family for building mobile app prototypes with simple HTML, CSS, and JS. It ships precompiled styles, platform themes for iOS and Android, an icon font (Ratchicons), and push.js for app-like page navigation.

## Use cases
- prototype a mobile app with HTML and CSS
- build an iOS-styled web app UI
- build an Android-styled web app UI
- create a home-screen web app that feels native
- quickly mock up mobile app screens for design testing

## When to choose
- you need lightweight HTML/CSS components to prototype a mobile app quickly
- you want a Bootstrap-like toolkit with iOS and Android platform themes
- you are building a simple home-screen web app without a heavy framework

## When to avoid
- you need a modern, actively developed mobile UI framework
- you require native app capabilities or app-store distribution
- you need broad browser support beyond WebKit-era targets
- you are building a complex production mobile application
