Posit Connect

Posit Connect is a publishing platform for all the work your teams create in R and Python. Share Shiny and Dash applications, R Markdown reports and Jupyter Notebooks, dashboards, plots, Plumber and Flask APIs, and more in one convenient place. Use push-button or git-backed deployment, scheduled execution of reports, and flexible security policies to bring the power of data science to your entire enterprise. Posit Connect is software that you run behind your firewall.

Consider Posit Connect if you can answer yes to these questions:

  1. Do you want push button or git-backed publishing?
  2. Do you want to publish R Markdown documents, Plumber API's, and Python Content in addition to Shiny (for R or Python) applications?
  3. Do you want a user interface so that content creators can manage their own data products?


Shinyapps.io is a software as a service (SaaS) product hosted in the cloud by Posit. It has both free and paid plans. Anyone can publish their Shiny apps to shinyapps.io with the push of a button. You don’t need to own a server or know how to configure a firewall to deploy and manage your applications in the cloud. No hardware, installation, or annual purchase contract required. Shinyapps.io is software that Posit hosts for you in the cloud.

Use Shinyapps.io if you can answer yes to all of these questions:

  1. Are you okay with your application being outside your firewall?
  2. Are you okay with the data that the application is pulling from being accessible to our cloud?
    (You have to open up a hole in your firewall if the data is behind the firewall today.)
  3. Are you okay with your end client creating a user account on shinyapps.io (if you are looking to use authentication).
  4. Are you okay with a shared computation platform for your analyses? (for example, we don’t have any SLAs today on performance)
