There’s an app here:

However, this Xfinity page does say: “You can’t use the Xfinity Stream app on Roku prior to installation of your Xfinity Internet and Xfinity TV services.”

I wonder if they just assumed you are using them for internet or if it mandates it.
Its like you look up a recipe that involves a particular brand. The recipe still works if you put in the ingredients from other brands however they want you to use their own.
If you pay Xfinity for TV, you can download Xfinity Stream on Roku. I did away with my 2nd cable box that way
