## What it is
MPush is an open-source real-time message push system written in Java on Netty, with a modular server, SDKs for Android, iOS, Java, and JavaScript, and cluster support via ZooKeeper and Redis. It provides secure TCP long-connection push with RSA-based handshake encryption, reconnection handling, and HTTP proxying.

## Use cases
- send push notifications to android and ios apps from my own server
- self-hosted open source push notification service
- build an instant messaging backend with tcp long connections
- real-time message delivery to mobile clients over tcp
- clustered push server with load balancing
- iot device message push over tcp

## When to choose
- you want a fully open-source, self-hosted push system with mobile SDKs
- you need clustered, load-balanced push backed by ZooKeeper and Redis
- you want encrypted, low-latency TCP push with weak-network reconnection

## When to avoid
- you only need simple FCM/APNs relay push rather than a custom TCP protocol
- you need an actively developed project - releases have been sparse since 2022
- your stack is not JVM-based on the server side

## Facets
- artifact type: service
- maturity: maintenance
- function: message-queue, websocket, http-server, networking, monitoring, security
