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
