## What it is
RxNetty is a Reactive Extensions (Rx) adaptor for Netty, providing reactive APIs for building HTTP and TCP clients and servers on the JVM. It integrates Netty's asynchronous networking with RxJava's observable streams.

## Use cases
- build reactive http servers in java
- write async http clients with rxjava
- handle streaming network io reactively
- compose netty networking with observable streams
- build tcp clients and servers with reactive backpressure

## When to choose
- you already use RxJava and Netty together
- you want reactive streams over Netty networking
- you maintain legacy Netflix-style reactive JVM services

## When to avoid
- starting a new project - the project is no longer under active development
- you prefer newer reactive stacks like Reactor Netty
- you need long-term support or frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: http-client, http-server, middleware, concurrency
- domain: backend, networking, developer-tools, apis
- platform: jvm, cross-platform
- tags: reactive-extensions, netty, rxjava, async-io, http
