Web-Based R Servers (Shiny and WebReports)

Shiny is a web front-end application for R that is part of RStudio.  Shiny is licensed at $9,999/year through RStudio.

I've been playing with it the last few days and its okay -- I think it is based on some TCL/TK as thats how you set up the webpage -- through a structure like it. 

My first application was to query PubMed and then have t report on the various aspects of it -- such as publication year, journal, authors, etc.

I have not figured out how the inputs work (checkbox, slider, etc).  The documentation explains simple uses of it -- but does not solve my unique use-case.

How does this compare to WebReports:

• I like the input parameters alot better in WebReports than in Shiny.
• Shiny has the ability to dynamically change content without refreshing the webpage.
• WebReports has the ability to email and print reports while Shiny does not.
• WebReports R was developed in 2007.. so 7 years we can adopt technology from back then. 
• Shiny is free (non-password version) -- WebReports is unknown.
