Complementary monads library?

What monad/ADT libraries are people using with ramda?

Most of those previously recommended (folktalke, fluture, ramda-fantasy) are no longer maintained. Packages which are maintained such as sanctuary seem to promote themselves as a superior alternative to ramda, not a complementary library.

In my view, there is no other FP library as comprehensive or well maintained as ramda and I don't want to ditch it. However, I would like to use things such as Maybe, Either, Future (Task/Deferred/However you want to call it) in critical sections of code (but not necessarily the whole codebase).

Are there any production-ready, well supported libraries out there?
