shiny 
Easily build rich and productive interactive web apps in R — no HTML/CSS/JavaScript required.
Features
- An intuitive and extensible reactive programming model which makes it easy to transform existing R code into a "live app" where outputs automatically react to new user input.
- Compared to event-based programming, reactivity allows Shiny to do the minimum amount of work when input(s) change, and allows humans to more easily reason about complex MVC logic.
- A prebuilt set of highly sophisticated, customizable, and easy-to-use widgets (e.g., plots, tables, sliders, dropdowns, date pickers, and more).
- An attractive default look based on Bootstrap which can also be easily customized with the bslib package or avoided entirely with more direct R bindings to HTML/CSS/JavaScript.
- Seamless integration with R Markdown, making it easy to embed numerous applications natively within a larger dynamic document.
- Tools for improving and monitoring performance, including native support for async programming, caching, load testing, and more.
- Modules: a framework for reducing code duplication and complexity.
- An ability to bookmark application state and/or generate code to reproduce output(s).
- A rich ecosystem of extension packages for more custom widgets, input validation, unit testing, and more.
