GS2-Matchmaking vs Namazu Elements

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.

Namazu Elements is an open-source backend server and LiveOps platform for online and connected multiplayer games. It includes player accounts and profiles, matchmaking, leaderboards, inventory, missions, and in-game economy tools. REST and WebSocket APIs, along with direct database APIs, connect clients and backend services. The maker describes WebRTC-based matchmaking and peer-to-peer real-time multiplayer support. A CMS lets teams manage in-game content and create or test entities without deploying new code. Listed integrations include Unity, GameMaker, and Godot, and developers can extend server logic in Java, Kotlin, Scala, or another JVM-compatible language. Deployment options include local Docker, self-hosting in a cloud account, AWS Marketplace, and a managed cloud beta. The product uses a server-authoritative security model and is designed for self-hosting, which the maker says lets customers retain ownership of backend and player data. Community Edition is free under MPL 2.0 and self-hosted. Namazu Cloud is in closed beta, with a one-month free trial for accepted teams.
