RabbitMQ vs Redis: What are the differences?
Developers describe RabbitMQ as "A messaging broker - an intermediary for messaging". RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received. On the other hand, Redis is detailed as "An in-memory database that persists on disk". Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
RabbitMQ and Redis are primarily classified as "Message Queue" and "In-Memory Databases" tools respectively.
"It's fast and it works with good metrics/monitoring" is the primary reason why developers consider RabbitMQ over the competitors, whereas "Performance" was stated as the key factor in picking Redis.
RabbitMQ and Redis are both open source tools. Redis with 37.4K GitHub stars and 14.4K forks on GitHub appears to be more popular than RabbitMQ with 5.95K GitHub stars and 1.78K GitHub forks.
According to the StackShare community, Redis has a broader approval, being mentioned in 3261 company stacks & 1782 developers stacks; compared to RabbitMQ, which is listed in 940 company stacks and 548 developer stacks.
