GIM is a high-performance instant messaging server written in Go, designed as a set of service components (connect, logic, business) that can be integrated into business systems. It supports TCP and WebSocket access, multi-device sync, offline messages, and single/group/room chat with horizontal scaling.

Use cases

• add chat to my app
• self-host an IM server in Go
• build group chat with offline message sync
• support multi-device login with real-time message sync
• deploy a scalable websocket chat backend
• integrate IM as a component into an existing business system

When to choose

• you need a self-hosted, horizontally scalable IM backend in Go
• you want TCP and WebSocket client access with gRPC internal services
• you need offline message storage and seq-based sync
• you want to plug in your own auth via a gRPC interface

When to avoid

• you need a turnkey end-user chat product with polished clients
• you prefer a managed SaaS chat service
• your stack is not Go or cannot run MySQL/Redis
