Questions tagged [shiny-server]

Shiny Server provides a platform on which you can host multiple Shiny applications on a single server, each with their own URL or port.

Shiny Server is a server program that makes Shiny applications available over the web.

Using Shiny Server, you can host multiple Shiny applications, as well as static web content, on a Linux server and make them available over the internet. You can specify what applications are available at what URL, or configure Shiny Server to let anyone with a user account on the server deploy their own Shiny applications.
