Welcome to the MongoDB C++ driver. On this site, you'll find documentation to help you get the most from MongoDB and C++. If you're just starting out, take a look at these pages first:

Driver Status by Family and Version

Stability indicates whether this driver is recommended for production use. Currently, no drivers guarantee API or ABI stability.

For documentation about previous releases, see the legacy documentation.

Current Driver

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.

Compatibility

MongoDB Compatibility

The following compatibility table specifies the recommended version or versions of the MongoDB C++ driver for use with a specific version of MongoDB.

The first column lists the driver version.

Important

MongoDB ensures compatibility between the MongoDB Server and the drivers for three years after the server version's end of life (EOL) date. To learn more about the MongoDB release and EOL dates, see MongoDB Software Lifecycle Schedules.
