A barebones WebSocket client and server library written in 100% Java, built on java.nio for a non-blocking, event-driven model. It implements the RFC 6455 and RFC 7692 WebSocket protocols and is distributed via Maven Central under the MIT license.

Use cases

• implement a websocket server in java
• connect to a websocket endpoint from a java application
• add real-time bidirectional messaging to a jvm backend
• handle wss secure websocket connections in java
• build a lightweight event-driven socket server without a full framework

When to choose

• you need a minimal, dependency-light WebSocket implementation on the JVM
• you want direct control over the WebSocket lifecycle via subclassing
• you need RFC 6455 and permessage-deflate (RFC 7692) support in Java

When to avoid

• you need a full-featured framework with routing, sessions, and middleware
• you are building a reactive or Spring-based stack with its own WebSocket support
• you need client support outside the JVM
