About Game Server Backend

Game Server Backend (GSB) is a comprehensive hosted backend platform specifically designed for studios and indie developers focused on creating multiplayer games. It streamlines the operational infrastructure required for multiplayer titles into a single, cohesive API, enabling teams to launch their games efficiently without the burden of building backend services from the ground up. GSB encompasses various essential features, including matchmaking, global and regional leaderboards, player profiles, and persistent JSON state storage per user. Additionally, it offers a server registry for community-server discovery, in-game economy primitives, and a live-ops configuration layer to facilitate gameplay tuning updates without necessitating client patches. The platform supports three authentication methods: anonymous accounts, passwordless email sign-in, and Steam OpenID for PC games. With SDKs available for Unity, Unreal Engine, and Godot, GSB ensures type-safe APIs that align seamlessly with existing engine patterns, making it easy for developers to integrate. Its versatility extends to Roblox and custom game servers, positioning GSB as an ideal choice for any multiplayer project. Importantly, GSB eliminates the need for multiple vendors for authentication, persistence, and server discovery, providing a streamlined path from prototype to live production. The free forever Dev plan, with no credit card requirement, makes it accessible for teams of all sizes to leverage its capabilities.

Features

Player Authentication

GSB offers a robust player authentication system that includes email and password logins, guest sessions, and OAuth integration with platforms like Google, GitHub, and Discord. This feature enables developers to support real accounts and provide seamless onboarding without the need to build custom authentication solutions from scratch.

Persistent Player Data

With GSB, developers can manage player-scoped and project-scoped JSON documents for various data types, including progression, profiles, inventories, and event flags. This server-authoritative setup ensures data integrity and facilitates patch semantics, allowing for reliable storage and retrieval of player information.

Leaderboards

The platform provides ranked and seasonal leaderboards equipped with configurable rules, fast ranking reads, and support for timed events. GSB also includes anti-cheat mechanisms to manage score submissions, ensuring fair competition and an engaging experience for players.

Live Config Delivery

GSB enables developers to upload versioned configuration bundles, activating them per environment. This feature allows teams to implement balance changes, loot tables, and rulesets on the fly, eliminating the need for full client patches and streamlining gameplay updates.

Use Cases

Indie Game Development

Indie developers can leverage GSB to rapidly prototype and launch their multiplayer titles without the complexity of backend development. The unified API simplifies the integration process, allowing teams to focus on gameplay experiences rather than backend logistics.

Community-driven Games

For games that emphasize community engagement, GSB's dedicated server registry facilitates server discovery, enabling players to find and join community-hosted servers easily. This feature enhances player interaction and fosters a vibrant gaming community.

Live Operations Management

Games requiring ongoing live operations can utilize GSB’s live config delivery to manage real-time game balancing and seasonal updates. This capability ensures that developers can quickly respond to player feedback and maintain game engagement over time.

Cross-platform Multiplayer

GSB supports various platforms, including Unity, Roblox, and custom game servers, making it suitable for cross-platform multiplayer games. This flexibility allows developers to reach a wider audience and provide a consistent experience across different gaming environments.
