Yes, R has the now-RStudio-supported plumber package (https://github.com/trestletech/plumber), roughly flask for R.
There's also opencpu (https://github.com/opencpu/opencpu), though the pros/cons of one vs the other has never been clear to me.

Unfortunately, not even close to flask. Plumber doesn't even handle concurrency...

I'm curious to see how https://github.com/thomasp85/fiery performs and if anyone has used that. May be higher performance than plumber (re: concurrency) because I get the sense from the docs that it's closer to libuv.
