EJDB [0] is pretty good and seems to be actively developed again after a period of inactivity. It uses BSON rather than JSON directly but close enough, and the queries are modelled after Mongo too.

I made a C++14 wrapper [1] a while ago which will probably still work unless EJDB itself had some drastic API changes. (I also have a C++14/1y BSON/JSON library [2] that's handy for working with EJDB, but is a bit of a playground for template metaprogramming so compile times will explode with certain functionality).

The main problem with EJDB is that it's not crash tolerant so you need signal handlers to attempt a graceful flush/close on a global handle.

I took a look at EJDB recently and thought it looked like a pretty neat project. One potential gotcha is that it is built on TokyoCabinet which AFAIK is no longer maintained. Looks like they have plans to build a v2, though.
