MSMQ vs RabbitMQ: What are the differences?
Developers describe MSMQ as "A technology for asynchronous messaging". This technology enables applications running at different times to communicate across heterogeneous networks and systems that may be temporarily offline. Applications send messages to queues and read messages from queues. On the other hand, RabbitMQ is detailed 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.
MSMQ and RabbitMQ belong to "Message Queue" category of the tech stack.
RabbitMQ is an open source tool with 5.95K GitHub stars and 1.78K GitHub forks. Here's a link to RabbitMQ's open source repository on GitHub.
