Idem

What Idem is

Idem provides matchmaking for multiplayer games, matching players by skill and supporting both casual and elite play. Its matchmaker handles PvPvP formats with flexible numbers of players per team and teams per match. Players can enter as pre-arranged parties, and the system can fill a place when someone leaves. It considers ping and suggests a suitable server location. Ratings use Bayesian updates similar to TrueSkill or Glicko II, while queue-liquidity analytics estimate how larger modes or ping limits may affect queue availability. Idem offers hosting and game-backend integrations, along with sign-in choices including Google, Facebook, GitHub, Discord, Steam, and username/password. It is available as managed cloud software or as a self-hosted solution. The free Community Edition is Open Match compatible and provides basic algorithm selection; advanced commercial matchmaking is intended for more complex requirements. Self-hosted matchmaking runs as a lightweight, stateless container in the customer’s infrastructure, with a synchronous API for submitting tickets and game-mode settings and receiving matches or unmatched tickets.
