As one of the largest and earliest instant messaging (IM) developers in China, CommsEase has accumulated more than 15-year experience in communication technology from the very first product POPO to EasyChat later offered. CommsEase has integrated highly stable and reliable IM features of these products, so that developers can integrate IM feature into their APPs at lower costs.

CommsEase SDK (NIM SDK) provides a complete IM feature development framework for mobile applications. By hiding complex internal details and providing relatively simple API interfaces externally, this framework can facilitate fast integration of IM features by third-party applications. The SDK is compatible with Windows xp (sp3 and above), Windows 7, Windows 8/8.1, and Windows 10. Starting from V3.2.5, the SKD can be fully accessed by 32-bit and 64-bit programs.
