What is Game Server Backend?
Game Server Backend (GSB) is a hosted backend platform tailored for multiplayer games. It unifies player authentication, persistent data storage, leaderboards, matchmaking, dedicated server registration, live configuration delivery, economy, and social features—all accessible through a single API. Designed for live games, GSB eliminates the need to stitch together multiple vendors and custom scripts, allowing developers to focus on gameplay.
GSB supports Unity, Roblox, Godot, and custom game servers. It provides first-party SDKs and a REST API, with three trust-boundary modes: API keys for admin scripts, server tokens for game servers, and player JWTs for authenticated clients. The dashboard offers real-time observability of player activity, server heartbeats, and config pushes, along with SDK quickstarts and environment management.
