Open Match is an open source game matchmaking framework that simplifies building a scalable and extensible Matchmaker. It is designed to give the game developer full control over how to make matches while removing the burden of dealing with the challenges of running a production service at scale.

This repository is the public preview of the proposed second version of Open Match and contains protobuffer definition files (proto), golang application (core), and external-facing golang modules (pkg). The subdirectories themselves contain further documentation, but at a high level:

• proto contains Protocol Buffer definitions used to produce libraries in your language of choice. Open Match 2 is written in golang but you can write your matchmaker in any language supported by gRPC.
• core (also called om-core in places where it may not be obvious that it is part of Open Match) is the core Open Match 2 application. It serves all the Open Match 2 API endpoints from a single horizontally-scalable container image.
• pkg contains two external golang modules:
  • open-match.dev/open-match2/pkg/pb/v2 contains the compiled golang modules produced by protoc.
  • open-match.dev/open-match2/pkg/api/v2 contains the grpc-gateway reverse-proxy server which translates RESTful HTTP API calls into gRPC.
