Celery vs RabbitMQ: What are the differences?
Celery: Distributed task queue. Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well; RabbitMQ: 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.
Celery and RabbitMQ belong to "Message Queue" category of the tech stack.
"Task queue" is the primary reason why developers consider Celery over the competitors, whereas "It's fast and it works with good metrics/monitoring" was stated as the key factor in picking RabbitMQ.
Celery and RabbitMQ are both open source tools. It seems that Celery with 12.9K GitHub stars and 3.33K forks on GitHub has more adoption than RabbitMQ with 5.94K GitHub stars and 1.78K GitHub forks.
reddit, 9GAG, and Rainist are some of the popular companies that use RabbitMQ, whereas Celery is used by Udemy, Robinhood, and Sentry. RabbitMQ has a broader approval, being mentioned in 940 company stacks & 548 developers stacks; compared to Celery, which is listed in 272 company stacks and 77 developer stacks.
