The Platform

Infrastructure That Disappears.
Gameplay That Doesn't.

When your backend just works, your team builds better games. That's the whole idea.

Three layers. One integration.

GameStack's architecture connects your game client to a global server fleet through a single SDK call.

SDK Integration

Native SDKs for Unity, Unreal, and Godot. One API surface. Works the same across all engines.

Server Fleet

Dedicated game servers that scale up in seconds. You define the image. We handle the fleet.

Global Routing

32 nodes route players to the lowest-latency server automatically. No configuration required.

Everything multiplayer, already built

Stop rebuilding systems other studios already threw away. Use ours.

Dedicated Servers

Full-authority server instances with persistent state. Your game logic runs server-side. Players connect, not host. No peer-to-peer latency issues, no cheat vectors from client-side authority.

Relay Network

When players need indirect connections | firewalls, carrier-grade NAT, mobile networks | the relay network handles it transparently. Same API, same latency targets, no extra work on your end.

Matchmaking Engine

Define your own matchmaking rules | skill brackets, region priority, party size, ping limits. The engine handles queue management, backfill, and timeout escalation. You write the rules; it runs them.

Game Analytics

CCU over time, regional latency distributions, server error rates, match completion rates. The data your ops team actually needs, not a generic cloud dashboard. Alerts included.

32 nodes. Every major region covered.

North America, Europe, Asia-Pacific. Players always connect to the nearest node.

Global Server Network Map

Integrate in a weekend

Native packages for the three most-used game engines. Same API across all of them.

Unity SDK
using GameStack;

var client = new GSClient("your-api-key");
await client.Matchmaking.FindMatch(new MatchConfig {
  Mode = "ranked",
  Region = Region.Auto
});
Unreal SDK
UGameStackClient* Client = 
  NewObject<UGameStackClient>();
Client->Initialize("your-api-key");
Client->Matchmaking->FindMatch(
  FMatchConfig(EMode::Ranked, 
               ERegion::Auto));
GDScript (Godot)
var client = GameStackClient.new()
client.initialize("your-api-key")
var match = await client.matchmaking\
  .find_match({
    "mode": "ranked",
    "region": "auto"
  })
