## What it is
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

## Facets
- artifact type: service
- maturity: active
- function: websocket, rpc, http-server, message-queue, auth
- domain: backend, developer-tools
