When using WebSocket, whether Redis or RabbitMQ is better depends on your specific use case12.

Redis is a fast in-memory key-value store with optional persistence. The pub/sub feature of Redis is a marginal case for Redis as a product2. It’s lightweight and can be used for real-time messaging1. However, it doesn’t guarantee message delivery if a subscriber is not active when the message is published2.

RabbitMQ, on the other hand, is a message broker that is optimized for reliable delivery of messages2. It supports advanced messaging patterns and has features like message queuing, delivery acknowledgment, and persistent messages2. However, it might be overkill if you just need simple pub/sub functionality1.

Here are some considerations:

• If you need a lightweight solution for real-time messaging, Redis might be a good choice1.
• If you need guaranteed message delivery, or if you’re using complex messaging patterns, RabbitMQ might be more suitable2.
• If you’re already using RabbitMQ for other parts of your system, it might make sense to use it for WebSocket communication as well1.

Remember, it’s important to choose the right tool based on your specific needs and the structure of your application12.
