What Open Match is

Open Match is a free, open-source framework for building a game matchmaker. Developers write the logic that groups tickets into matches and can customize criteria for different game modes. Its FrontendService manages tickets, BackendService generates matches and assignments, and QueryService searches tickets using constraints. A custom Match Function retrieves tickets and proposes matches; an optional Evaluator can remove overlapping proposals, with a default available for common cases. Backfill can fill open places in multiplayer matches, but requires changes to the Match Function and game servers. Open Match supports measuring match quality and latency and running experiments to balance them. Its resource-based REST APIs run over HTTP and gRPC and conform to OpenAPI. The framework is self-hosted in a Kubernetes cluster, installed with Helm or static Kubernetes YAML. Documentation covers telemetry, TLS encryption, and connections to external frontends, Directors, and dedicated game server allocation systems. HTTP and gRPC are unencrypted by default; TLS is supported, but all servers must enable it together. The production Helm setup is described as requiring significant resources. Open Match is licensed under Apache 2.0.

Who it suits

Open Match suits developers who want to build and operate their own game matchmaking logic in Kubernetes. It is for teams prepared to customize match functions and manage deployment requirements.

What it does well

Developers control matchmaking logic
Supports match quality and latency measurement
Provides REST APIs over HTTP and gRPC
Offers TLS transport encryption
Includes a default Evaluator for common cases

What to know first

Self-hosting requires a Kubernetes cluster
APIs are unencrypted by default
Production setup requires significant resources
Backfill requires custom changes

Limits

The production guide says its recommended Helm configuration requires significant resources for production workloads. The free plan is Open Match itself, self-hosted in a Kubernetes cluster.

Getting started

Visit https://open-match.dev/
Prepare a Kubernetes cluster for self-hosted deployment
Install with Helm or static Kubernetes YAML files
Build a custom Match Function and add matchmaking criteria
Use the tutorials to build a game mode based matchmaker in Golang

Verdict

Open Match provides building blocks rather than a ready-made matchmaking service, with customization central to how matches are formed. Teams should account for Kubernetes operations, production resource needs, and TLS configuration.

Questions

How much does Open Match cost?

The listed plan is free.

Is Open Match open source?

Yes. The project repository identifies its license as Apache 2.0.

Where does Open Match run?

It is self-hosted in a Kubernetes cluster and can be installed with Helm or static Kubernetes YAML files.

Does Open Match provide multiplayer networking or player accounts?

No. Multiplayer networking and player accounts are listed as unsupported; matchmaking is supported.

How does Open Match handle encrypted API traffic?

HTTP and gRPC channels are unencrypted by default, and TLS transport encryption is supported. All servers must enable TLS together; mixed encrypted and unencrypted modes are unsupported.
