goim is a high-performance instant messaging (IM) push server written in pure Go, supporting WebSocket, TCP, and HTTP long-polling protocols. It uses a scalable comet/logic/job architecture with Kafka-based asynchronous message pushing, supporting single push, multi-push, and broadcast to millions of concurrent connections.

Use cases

• build a real-time chat server backend
• push notifications to millions of connected clients
• implement websocket messaging at scale
• broadcast live messages to many subscribers
• self-host an instant messaging push service
• add real-time messaging to a mobile app

When to choose

• you need a proven, benchmarked Go IM server handling millions of concurrent connections
• you want multi-protocol support (WebSocket, TCP, HTTP long-polling) out of the box
• you need scalable horizontal architecture with Kafka-based async push
• you want battle-tested code originating from Bilibili's infrastructure

When to avoid

• you need a full-featured chat product with UI, history, and group management - goim is a push layer only
• you want a simple small-scale websocket server without distributed complexity
• you prefer not to operate Kafka and service discovery dependencies
• you need active community support - development has slowed with the last release in 2023
