## What it is
Shiny is an R (and Python) package for building interactive web applications entirely in R or Python code, without needing HTML, CSS, or JavaScript. It uses a reactive programming model so outputs automatically update when user inputs change, with prebuilt widgets and a Bootstrap-based default UI.

## Use cases
- build interactive dashboards for data analysis in R
- turn an R analysis script into a live web app
- let users explore datasets with sliders and dropdowns without writing JavaScript
- embed interactive apps inside R Markdown documents
- create data science web apps without web development skills
- prototype interactive visualizations with ggplot2

## When to choose
- you work in R or Python and want interactive web apps without learning web development
- you need reactive dashboards for data exploration or reporting
- you want quick prototyping of analytics tools with built-in widgets

## When to avoid
- you need a highly custom, pixel-perfect frontend with full control over HTML/CSS/JS
- you are building a large-scale production web service or API
- your team primarily works in JavaScript-centric web frameworks
