xxim-server is a 100% open-source instant messaging (IM) server written in Go using the go-zero framework, designed so anyone can self-host their own chat platform and retain ownership of their data. It supports rich message types, offline message retrieval, large group chats (up to 200k members), end-to-end encryption, and P2P connections without a public IP.

Use cases

• self-host a private chat server for friends or community
• build a custom messaging app without third-party IM providers
• run an IM server without a public IP using P2P connections
• deploy a chat platform with end-to-end encrypted messaging
• support very large group chats with hundreds of thousands of members
• keep full ownership and control of chat message data
• integrate IM functionality into an existing product via SDK

When to choose

• you want a self-hosted, open-source IM backend with full data ownership
• you need unlimited offline message history without day/count limits
• you require very large group chats (up to 200k members)
• you want end-to-end encryption and P2P connectivity out of the box
• you prefer a lightweight Go server with low resource usage and simple deployment

When to avoid

• you need a battle-tested, commercially supported IM solution with active maintenance
• you require guaranteed vendor push notifications, which are not yet implemented
• you want a turnkey hosted service rather than running your own infrastructure
• you need a project with a clear license file and stable, non-refactoring codebase
• you expect polished client apps today - the universal SDK is still in development
