Shiny Server and Shiny Server Pro are now available.

This release of Shiny Server Pro includes floating license support and Shiny Server contains a small enhancement to the way errors are displayed. We recommend upgrading at your earliest convenience.

Shiny Server

Shiny Server Pro

This release adds floating license support through the license_type configuration directive. Full documentation can be found at

Floating licensing allows you to run fully licensed copies of Shiny Server Pro easily in ephemeral instances, such as Docker containers, virtual machines, and EC2 instances. Instances don’t have to be individually licensed, and you don’t have to manually activate and deactivate a license in each instance. Instead, a lightweight license server distributes temporary licenses (“leases”) to each instance, and the instance uses the license only while it’s running.

This model is perfect for environments in which Shiny Server Pro instances are frequently created and destroyed on demand, and only requires that you purchase a license for the maximum number of concurrent instances you want to run.
