Agones

What Agones is

Agones is a free, open-source platform for deploying, hosting, scaling, and orchestrating dedicated game servers for large-scale multiplayer games on Kubernetes. Teams can operate and update server fleets without shutting down servers that have active players. Its integrated game server SDK supports lifecycle management, including health checks, state management, and configuration. Game servers must integrate an Agones client SDK for state management and health checking. Agones also includes autoscaling, metrics, and log aggregation for game server sessions.

Documented SDKs cover Unreal Engine, Unity, C++, C#, Node.js, Go, Rust, Python, and REST. The installation guide lists Google Kubernetes Engine, Azure Kubernetes Service, Amazon EKS, and Minikube as supported Kubernetes environments. Agones 1.61 supports Kubernetes versions 1.34, 1.35, and 1.36. Linux amd64 is stable; Linux arm64 and Windows amd64 are alpha. Deployment security depends on cluster configuration, including RBAC, network policies, allocator TLS, and node isolation. The SDK sidecar is compatible by default with Kubernetes' restricted Pod Security Standard, while game servers and other pod containers need their own compliant security contexts. The FAQ recommends clusters no larger than 500 nodes as a rule of thumb and advises load testing for a game's workload.

Who it suits

Agones suits teams hosting multiplayer game servers that want to manage infrastructure on Kubernetes, in cloud or on-premises environments. It is a fit for teams prepared to integrate the client SDK and configure and operate their clusters.

Limits

The free Agones plan runs on Kubernetes and is for Linux game servers. With Agones 1.61, supported Kubernetes versions are 1.34, 1.35, and 1.36; Linux arm64 and Windows amd64 are alpha, and alpha features may be buggy or dropped without notice.

Getting started

1. Visit the Agones website and follow its installation guide.
2. Choose a supported Kubernetes environment: GKE, AKS, Amazon EKS, or Minikube.
3. Use Kubernetes 1.34, 1.35, or 1.36 with Agones 1.61.
4. Install Agones in your Kubernetes environment.
5. Integrate an Agones client SDK into each game server for state management and health checking.
6. Configure cluster security, including RBAC, network policies, allocator TLS, and node isolation.

Verdict

Choose Agones if you need a free, self-hosted way to manage dedicated multiplayer game servers on Kubernetes and can integrate its client SDK. Look elsewhere if you need a managed deployment model or cannot take responsibility for cluster configuration and security.
