## What it is
WuKongIM is a high-performance, channel-oriented instant messaging server written in Go that handles message persistence, replication, ordering, presence, and offline sync with zero external dependencies. It supports single-node and distributed cluster deployments and ships SDKs for iOS, Android, Web, and Flutter.

## Use cases
- build a self-hosted chat app with group and private messaging
- send push notifications and real-time updates to users
- connect IoT devices via a lightweight messaging channel
- power live stream chat with high fan-out
- add customer service live chat to a product
- build an AI chatbot messaging backend
- implement WebRTC signaling for video calls

## When to choose
- you need a self-contained IM server with no external database, cache, or message queue
- you need very high message throughput (tens of thousands of messages per second per node)
- you want to scale from a single node to a Raft-based cluster with online expansion
- you need guaranteed per-channel message ordering, offline sync, and multi-device sessions

## When to avoid
- you need a fully stable API - v3 is in beta and formats may change
- you need cross-country data node deployment, which is not yet supported
- you want a fully managed SaaS chat service rather than self-hosting
- your project requires a permissively licensed dependency - licensing should be verified
