Open-IM-Server is an instant messaging server developed using pure Golang, adopting JSON over WebSocket as the communication protocol. In Open-IM-Server, everything is a message, so you can easily extend custom messages without modifying the server code. With a microservice architecture, Open-IM-Server can be deployed using clusters. By deploying Open-IM-Server on a server, developers can quickly integrate instant messaging and real-time networking features into their applications, ensuring the security and privacy of business data.
Open-IM-Server is a robust instant messaging server engineered using pure Golang, leveraging JSON over WebSocket for communication. The server treats everything as a message, facilitating straightforward customization without modifying the server code. Its microservice architecture enables deployment using clusters, ensuring high performance and scalability.
Open-IM-Server is not a standalone product and does not include account registration and login services. For your convenience, we have open-sourced the [chat repository](https://github.com/OpenIMSDK/chat) which includes login and registration functionality. By deploying the chat business server alongside Open-IM-Server, a chat product can be set up.
Whether you're looking to integrate instant messaging or real-time networking into your applications, Open-IM-Server is your go-to solution! :rocket:
