Shiny is a web application framework for the R programming language, designed to make it easy to build interactive web applications directly from R. Developed by RStudio, Shiny allows users to create dynamic dashboards and visualizations without requiring extensive web development skills. It integrates seamlessly with R, enabling users to harness the power of R's data analysis capabilities in a user-friendly web interface. Shiny applications can be hosted on a variety of platforms, including RStudio's Shiny Server and ShinyApps.io. The official website, https://shiny.rstudio.com, provides documentation, tutorials, and resources to help users get started and develop advanced applications.
