Open Source Game Servers

Arianne is a multiplayer online engine to develop turn based and real time games, providing a simple way of creating the game server rules and clients like our MORPG Stendhal. Our engine Marauroa uses Java and SQL for hosting hundreds of players on a solo host. Stendhal is a fun friendly and free multiplayer online adventure game with a huge and rich world. With hundreds of NPCs and different quests, features like the Travel log and achievement system keep track of progress. Thousands of creatures are ready to fight, above and below ground, and as players level up they can compare themselves on a detailed stats website. The engine Marauroa provides a simple way of creating games on a portable and robust server architecture. Marauroa manages the client server communication and provides an object orientated view of the world for game developers. It handles database access in a transparent way to store player accounts, character progress and the state of the world

Multiplayer dedicated game servers anywhere. An open source, batteries-included, multiplayer dedicated game server scaling and orchestration platform that can run anywhere Kubernetes can run. Define and manage groups of ready-game servers through YAML configuration or API calls. Integrated SDK for managing game server lifecycle, health and configuration. Integration with OpenCensus for platform-independent game server metrics and monitoring dashboards. Agones replaces usual bespoke or proprietary cluster management and game server scaling solutions with a Kubernetes cluster that includes the Agones custom Kubernetes Controller and matching Custom Resource Definitions for GameServers, Fleets and more. With Agones, Kubernetes gets native abilities to create, run, manage and scale dedicated game server processes within Kubernetes clusters using standard Kubernetes tooling and APIs. This model also allows any matchmaker to interact directly with Agones via the Kubernetes API.

The Amazon GameLift Plugin for Unity contains libraries and native UI that makes it easier to access GameLift resources and integrate GameLift into your Unity game. You can use the GameLift Unity Plugin to access GameLift APIs and deploy AWS CloudFormation templates for common gaming scenarios. Auth Only, this scenario creates a game backend service that performs only player authentication and no game server capability. It creates a Cognito user pool to store player authentication information, as well as an API gateway REST endpoint backed up AWS Lambda handlers to start a game and view game connection information. The Lambda handler always returns a 501 Error (Unimplemented). Single-Region Fleet, this scenario creates a game backend service with a single GameLift fleet. After player authenticates and starts a game (with a POST request to /start_game), a AWS Lambda handler searches for an existing viable game session with an open player slot on the fleet.

Skynet is a lightweight online game framework which can be used in many other fields. Skynet is a lightweight framework designed for online game servers. Although from the feedback of the Community , it's not limited as a game server framework. On the Uses page, it shows a few projects that have used or currently using Skynet, but there are way more projects than listed. And welcome to be the next user. For Linux, install autoconf first for jemalloc. For FreeBSD , use gmake instead of make. Skynet now uses a modified version of lua 5.4.2 for multiple lua states. Official Lua versions can also be used as long as the Makefile is edited. With Socket API and SocketChannel , which makes it easier to implement socket pool and reconnect, you can use Skynet to call socket even asynchronously. Skynet doesn't force a specific protocol, you can come up with your own design.

Leaf, written in Go, is a open-source game server framework aiming to boost efficiency both in development and runtime. Simple APIs. Leaf tends to provide simple and plain interfaces which are always best for use. Self-healing. Leaf always tries to salvage the process from runtime errors instead of leaving it to crash. Multi-core support. Leaf utilize its modules and leaf/go to make use of CPU resouces at maximum while avoiding varieties of side effects may be caused. Each module runs inside a separate goroutine. Modules communicate with one another via a light weight RPC channel(leaf/chanrpc). Leaf suggests not to take in too many modules in your game server implementation. Gate module, for management of connection. Login module, for user authentication. Game module, for the main business.

LinuxGSM is the command-line tool for quick, simple deployment and management of Linux dedicated game servers. Traditionally game servers are not easy to manage yourself. Admins often have to spend hours messing around trying to get their server working. LinuxGSM is a command-line tool designed to be as simple as possible, allowing admins to spend less time on management and more time gaming. LinuxGSM will run on popular distros as long as the minimum requirements are met. Each game server has specific dependency requirements. Visit a specific game server installation page on the LinuxGSM website to check dependency requirements for the game server you want to install. LinuxGSM keeps itself and your game server updated. Using methods available from game developers to update including, SteamCMD, custom JSON or file archives, LinuxGSM can make sure you are running the latest version of your game server.

GAMERBREED gives you the power to create your own original online real-time browser-based MMO on your website. It's fully customizable, giving you control over armies, worlds, cities, quests, resources and much, much more. Also, if you have knowledge of HTML you will be able to create themes for your own unique game! The project is still under development and it will be released under GPL licence in July this year. In the meanwhile keep up to date with the project progress in the forum or check the latest designs!

Knapper is a Gaming Platform based on the Eclipse RCP. It provides Master/Game Server interfaces and communication protocol implementations. Furthermore it offers a GUI containing Lobby, Chat Rooms, Master Server capability and a User Management System.

Moon is a lightweight game server framework based on the actor model. One worker thread can have one or more actors (services), which communicate with each other through message queues. There are many features for game server development.

ScriptDev2 is an extension to the Massively Multiplayer Online Role-Playing Game Server - MaNGOS. ScriptDev2’s purpose is to provide small-scale scripts for use within MaNGOS and to provide developers information on how to work with modular application

TFOGS is a test framework for quick action game, it's anti-hack, and it provides a complete implementation to reduce lag.

A query tool for half life game server admins. Can query Source and GoldSource game servers. Supports split packet and compressed (bzip2) packet handling. Updated to support latest HL1 protocol48 changes.

This project is created to permit the usage of a more-stable, easy to use MaNGOS object-oriented Massively Multiplayer Online Role-Playing Game Server (MMORPGS). It doesn't include unreviewed changes, so it may look more feature-less than MaNGOS.

WeeBot is a .NET framework for hosting bots and testing game modifications to the Weewar online TBS game (weewar.com). It provides APIs for bot development as well as a client and single game server for hosting and testing bots offline.

XBashServ is a program written in Tcl to help set up and run game server programs and some other general network server programs on UNIX systems. It also works on Microsoft Windows but is experimental.

uIrcBot is a irc bot written in C++ for windows and unix. The bot can publish game-events from a counterstrike game server on an irc channel. The project includes a flexible and easy irc lib which handles the irc-events.

The Borg project is a framework for building MMORPG systems entirely written in c# . Borg provides the infrastructure and development framework with features like account authentication & management, message delivery, client and shared libraries... Update: this project is not active. You can still use it as a solid base for other projects or research.
