MobileIMSDK is a lightweight cross-platform instant messaging communication framework designed for real-time chat and push-style communication. It supports multiple client platforms, including iOS, Android, Java, HTML5, mini programs, UniApp, and HarmonyOS Next, with a Netty-based server side. The framework is notable for supporting UDP, TCP, and WebSocket protocols in the same open-source IM communication layer. It has been developed and refined over many years, making it a mature option for teams building custom messaging systems. MobileIMSDK focuses on the communication layer rather than a complete consumer chat app, so developers can build their own user interface and business logic on top of it. It is useful for mobile apps, web apps, enterprise messaging, live communication features, and custom push systems.
