You had Rserve by Simon for close to 20 years. There isn't much in terms of
fancy docs but it has been widely used. In essence, R runs "headless" and
connect to it (think "telnet" or "ssh", but programmatically), fire off
request and get results with zero startup latency.  But more work to build
the access layer.

And Rserve is also underneath RestRserve which allows you to query a running
server vai REST / modern web stack tech. (Think "plumber", but in C++ and
faster / more scaleable).

Lastly, there is Jeroen's OpenCPU.
