## What it is
MobileIMSDK is an original, lightweight cross-platform instant messaging (IM) communication-layer framework refined over 10 years. It uniquely supports UDP, TCP, and WebSocket protocols, with clients for iOS, Android, Java, H5, WeChat mini-programs, Uniapp, and HarmonyOS Next, and a Netty-based server.

## Use cases
- build a mobile chat app with a custom IM backend
- add real-time message push to Android and iOS apps
- implement cross-platform instant messaging with UDP TCP and WebSocket support
- self-host an IM server based on Netty
- add live messaging to H5 web apps and WeChat mini-programs
- integrate IM into Uniapp or HarmonyOS Next applications

## When to choose
- you need a battle-tested, lightweight IM transport layer across many platforms
- you want protocol flexibility across UDP, TCP, and WebSocket
- you need a self-hosted alternative to commercial IM SDKs like RongCloud or Huanxin
- you target niche platforms like HarmonyOS Next or WeChat mini-programs

## When to avoid
- you want a full-featured chat UI and business logic out of the box - this is only the communication layer
- you need built-in server clustering, which requires custom work
- you prefer a managed cloud IM service with no server maintenance
