## What it is
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

## Facets
- artifact type: library
- maturity: stable
- function: websocket, http-server, networking
- domain: web-development, backend, developer-tools
- platform: jvm, cross-platform
- tags: websocket-client, websocket-server, rfc6455, non-blocking-io, java-nio
