## What it is
JuggleIM is a self-hosted, high-performance instant messaging server written in Go, using a Protobuf + WebSocket long-connection protocol with REST APIs. It supports private chat, group chat, chatrooms, system notifications, bots/AI assistants, and multi-tenant deployments, with client SDKs for Android, iOS, Web, Flutter, and Electron.

## Use cases
- self-host a chat server for my app
- add private and group messaging to a mobile app
- build a live-stream chatroom
- run an instant messaging backend with WebSocket and REST APIs
- host a private WhatsApp/Telegram-style messenger
- add AI bot conversations to a chat app
- send system notifications to users in real time

## When to choose
- you want a self-hosted IM backend with full control over your messaging data
- you need multi-tenant support hosting several isolated apps from one deployment
- you need large group chats and unlimited-size live chatrooms
- you want client SDKs across Android, iOS, Web, Flutter, and Electron
- you need bot and AI assistant integration in your chat product

## When to avoid
- you only need simple peer-to-peer messaging without a server
- you prefer a managed SaaS chat service over operating your own infrastructure
- you need horizontal clustering on the free edition, which is limited to the professional edition
- your stack requires a non-Go server you can deeply customize in another language
