Epic Online Services vs GS2-Matchmaking

Epic Online Services is a suite of modular online services for game developers. Its service areas cover accounts and social features, multiplayer, player and game data, and trust and safety. Social capabilities include crossplay, friends, presence, overlay, and the Epic Games account ecosystem. Multiplayer tools include peer-to-peer features, sessions, lobbies, and voice chat. Developers can use leaderboards, stats, achievements, and storage for player and title data. Trust and safety services include Easy Anti-Cheat, sanctions, player reports, and Kids Web Services. The services can be used with Unreal Engine, Unity, or a developer's chosen engine. SDKs are available for PC in C or C#, Android, and iOS; console SDKs require a request through the Developer Portal. Epic describes the service as free to use, with no royalty or hosting fees, though usage restrictions may apply. Epic says it processes game-service data to operate the services and does not share partner data without explicit authorization. Use may be throttled or suspended for violations of service restrictions.

GS2-Matchmaking is a managed service for grouping game players by conditions and finding opponents. In standard matchmaking, a player creates a gathering and others may join when they meet its requirements; it is deleted after reaching its required player count. Conditions can include up to five player attributes, role capacities, ratings, allowlists, and blacklists. Ratings follow a Glicko-2-based process, starting at 1500 and changing with game results. Party tokens allow gatherings with existing party members; player tokens last 3 minutes and party tokens last 10 minutes. Season matchmaking keeps gatherings for a specified period and supports up to 1000 players, but only searches by GS2-Experience rank and does not allow players to leave during the season. The service supports latency or region matching and server allocation. SDKs cover Unity, Unreal Engine 5, Godot 4, Go, PHP, Java, C#, TypeScript, and Python. The Individual plan is free for eligible users, subject to request-rate thresholds and a GS2 logo requirement at launch.
