unable to run Radiant app

i want to run radiant app on local r studio without any addin so which source code I have refer from this github repository?

a quick scan tells me the radiant package simply registers itself as an rstudio add-in as a matter of course; you can launch it via other methods anyway; radiant::radiant() would do it.

but i want to host this radiant app on the cloud so I required the whole source code for hosting

I think you will struggle as it wasnt designed for that.
