   I thought once of making standalone version of Rubi. Just   
   by putting it in a CDF.   
      
   CDF just needs a free Mathematica player to run, and its   
   available on Linux, Mac and windows.   
      
   So one can a make a Rubi app. download it, and run it. No   
   Mathematica is needed.   
      
   Big issue which prevents this, is that WRI does not allow   
   free inputField in standard CDF app, where one can type   
   any expression as input.   
      
   Only numerical input is allowed in the inputField (where   
   one would type in the integrand).   
      
   Otherwise, the CDF could become a free copy of Mathematica   
   itself and used in place of Mathematica, since CDF comes with   
   full Mathematica engine inside it.   
      
   It looks like only CDF Player with EnterpriseCDF allows free input   
   evaluation based on this chart

   Another option is to put Rubi on a "wolfram cloud". This   
   though requires credit tokens to use and I never looked at how   
   all the different cloud options work, as they have so   
   many options now, it is very confusing for me.
