ShinyProxy is a way to deploy Shiny apps in an enterprise context. It has built-in functionality for LDAP authentication and authorization, makes securing Shiny traffic (over TLS) a breeze and has no limits on concurrent usage of a Shiny app.

Why use it?

  • you want to seamlessly deploy Shiny apps that were developed locally using the Shiny R package

  • you need enterprise features but want to stay with open source

  • you trust Java on the server side for running your Shiny apps
  • you want to get all benefits offered by Docker-based technology

Open Source

ShinyProxy is 100% open source, released under the Apache License version 2.0 and the sources are on Github.

For more information go to the shinyproxy.io website.
