## What it is
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
