The mongocxx is a ground-up rewrite of a C++ driver for MongoDB based on libmongoc. It requires a C++11 compiler. It is known to build on x86 and x86-64 architectures for Linux, macOS, Windows, and FreeBSD.

The mongocxx driver library includes a matching bson package, bsoncxx, that implements the BSON specification. This library can be used standalone for object serialization and deserialization even when one is not using MongoDB at all.

Releases of the mongocxx driver have version numbers like v3.x.y.

Note

There were no v2.x.y C++ drivers to avoid confusion with the deprecated legacy-0.0-26compat-2.x.y drivers.

MongoDB C++ drivers are available under the terms of the Apache License, version 2.0.
