Matchmaking API

Ship multiplayer.
Not matchmaking logic.

MatchKit handles skill-based matching, lobby management, and region routing so you can focus on your game. One API call. Any engine.

How it works

Three calls. Players matched.

No queuing system to design, no ELO logic to maintain, no server fleet to babysit.

Step 01
Register a player
Create a player once. MatchKit stores their skill and updates the rating after every match — the client never computes a score.
matchmaking.CreatePlayer(new PlayerRequest {
  username = "ace",
  region = "eu",
  matchmakingMode = MatchmakingMode.MMR,
  ratingMode = RatingMode.TS
}, created => { /* ... */ });
Step 02
Join the queue
Drop the player into a queue by game mode and team size. Region, rating, and modes are resolved server-side from the stored player.
matchmaking.JoinQueue(
  playerId,
  gameMode: "ranked",
  teamSize: 5
);
Step 03
Get matched in realtime
Subscribe once and let the server push events — queue-update when a match forms, match-ended with fresh stats. No polling.
_sse = matchmaking.Subscribe(playerId);
_sse.OnEvent += (name, json) => {
  if (name == "queue-update") Ready(json);
};
Features

Built for game developers,
not cloud architects.

Every feature exists because a developer hit a wall building it themselves.

Skill-based matching
MMR, ELO, or LP inputs with TrueSkill and MMR rating updates. Set the acceptable skill window per queue.
Rating that maintains itself
Wins, losses, KDA, and rating are tracked server-side and updated after every match. The client never manages state.
Queues & match modes
Define queues per game mode and team size. Relaxation parameters are configurable so wait times stay under control.
Realtime events
Server-Sent Events push queue-update and match-ended to each player. No polling, and the same events drive your UI.
Player & match APIs
Full player CRUD over REST plus a gRPC interface for server-to-server, with per-match history and lifetime stats.
Usage & match analytics
Request volume and matchmaking activity for your account, live from the API — right in the developer dashboard.

A native Unity SDK is available today; Unreal, Godot, and a JS/TS client are on the way. Until then, any engine integrates directly over the REST + SSE API — same features, full docs.
