✨ About OpenIM

Open-IM-Server, meticulously developed in pure Golang, is a powerful instant messaging server. Its distinct communication method, employing pb+websocket, views every interaction as a message, streamlining customization without altering server code. Built on a microservice architecture, it offers deployment through clusters for outstanding performance and scalability.

Open-IM-Server is more than an instant messaging server; it's a powerful tool for incorporating real-time networking into your applications, positioning itself as your premier choice for integration! 🚀

Please be aware that Open-IM-Server does not function as a standalone product and does not offer built-in account registration or login services. To ease your implementation process, we've open-sourced the chat repository, which comprises these features. Deploying this chat business server in conjunction with Open-IM-Server expedites the setup of a comprehensive chat product. 👥

Further enhancing your experience, we also provide an SDK client, wherein most complex logics are implemented. The SDK repository can be found at this link. The chat repository is our business server while the 'core' represents the high-level encapsulation of the SDK, synergistically working together to deliver superior results. ✨
