A distributed instant messaging (IM) chat system built in Go on top of WebSocket, designed to support up to a million concurrent connections on a single machine. It uses Gin for HTTP endpoints, gRPC for inter-node communication, and Nginx for load balancing, allowing horizontal scaling.

Use cases

• build a distributed chat/im system in go
• handle millions of websocket connections on one server
• learn how websocket long-connection servers work
• send messages to users or broadcast to all users over websocket
• deploy a horizontally scalable websocket backend with nginx and grpc
• check user online status and push real-time messages

When to choose

• you need a production-style Go IM/chat backend with websocket long connections
• you want a reference implementation of high-concurrency websocket connection management
• you need distributed message pushing across multiple nodes via gRPC

When to avoid

• you only need a simple websocket library rather than a full chat application
• you need end-to-end encryption or full IM features like message history and offline storage out of the box
• your stack is not Go
