Protocol Buffers ( protobuf ) is a data format for serialization with an interface description language . It was developed by Google Inc. and published in part under a 3-clause BSD license . An official implementation of Google as free software under Apache License 2.0 is provided for a large number of programming languages . The officially supported programming languages ​​include C # , C ++ , Go , Objective-C , Java , Python and Ruby , among others . Many other programming languages ​​such as C or Swift are supported by third-party projects.

The main design criteria of the Protocol Buffers are simplicity and performance . Therefore it is designed as a binary format in contrast to XML , which relies on a textual format.

Protocol Buffers were developed internally at Google from 2001 to 2008. The compiler and the libraries have been available under an open source license since 2008 , and Google's further development can be publicly monitored. Google uses protocol buffers to store and exchange structured data and as the basis for an RPC system for inter-machine communication.

gRPC uses Protocol Buffers as a description language for RPC interfaces and as a format for client-server communication.
