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.
