Jetserver (Nadron) is a high-speed Java NIO socket server designed specifically for network-based multiplayer games, built on Netty 4.1 for TCP/UDP transport and Jetlang for extremely fast in-VM message passing between player sessions and game rooms. It is highly configurable through Spring Framework 6 dependency injection, allowing any part of the server to be swapped with custom implementations.

Use cases

• build a multiplayer game server in java
• handle tcp and udp connections for online games
• low-latency realtime networking for multiplayer games
• manage game rooms and player sessions on the server
• high-throughput message passing between game sessions
• embed a configurable socket server in a java game backend

When to choose

• you are building a custom multiplayer game backend on the JVM and want control over sessions, rooms, and delivery
• you need both TCP reliability and UDP speed in one tuned server stack
• you want a highly configurable Netty-based server where components can be swapped via Spring DI

When to avoid

• you need a turnkey multiplayer service with built-in matchmaking, lobbies, and hosting rather than a server framework
• your project is not on the Java/JVM platform
• you need a general-purpose web or REST server rather than a game-tuned socket server
