Top 5 Open Source Message Queue (MQ) Softwares

An open source message queue (MQ) can be used to handle a variety of tasks asynchronously. It is used to enable process-related asynchronous communication within IT systems. Asynchronous communication means that the endpoints that are producing and consuming messages interact with only the queuing service, not with each other directly. This has the advantage of decoupling processes, making them more independent and therefore more scalable.

There are many different open source MQs available, each with its own advantages and disadvantages. Some of the most popular include ActiveMQ, Apollo, RabbitMQ and ZeroMQ. In general, MQs can be categorized into two main types: those that use a broker architecture, and those that use a peer-to-peer architecture. Broker architectures are generally more reliable and scalable, but can be more complex to set up and manage. Peer-to-peer architectures are simpler and easier to set up, but can be less reliable and scalable.

When choosing an open source MQ for your project, it is important to consider your specific needs and requirements. You should also be aware of the differences between the various MQs available, in order to choose the one that is best suited for your project.

Following are some of the most popular Open Source Message Broker Softwares:

Apache Kafka:

Apache Kafka is a high-throughput, low-latency messaging system that is capable of handling real-time data feeds. It is designed to provide durable and scalable messaging in a distributed environment. Kafka is a popular choice for many organizations because it offers a high degree of flexibility and reliability. One of the key features of Kafka is its ability to handle large volumes of data with minimal lag time. This makes it an ideal platform for applications that require real-time data processing, such as financial analytics or social media monitoring. Kafka is also highly scalable, which means it can easily handle increases in traffic without compromising performance. In addition, Kafka offers built-in redundancy and fault tolerance, which ensures that messages are delivered even in the event of server failure. Overall, Apache Kafka is an extremely powerful tool for handling real-time data streams.


RabbitMQ is the most widely deployed and popular open source best message broker software — an intermediary for messaging. Its popularity is due to its ease of use, robustness, and scalability. RabbitMQ is used in a wide range of applications including web applications, chat applications, online gaming, e-commerce, and Internet of Things. It offers reliable, asynchronous messaging that enables applications to communicate with each other. RabbitMQ is quick to install and has support for multiple programming languages. It is frequently used in microservices architectures where it acts as a backbone for communication between services. Thanks to its modular design, RabbitMQ can be easily extended with plugins. There are plugins available for monitoring, management, clustering, and high availability. RabbitMQ is an ideal choice for small to medium-sized projects as well as large enterprise deployments. It has a wide range of features that make it a highly flexible and powerful platform for asynchronous messaging.


Celery is an open source, flexible, and reliable distributed message queue system. It is written in Python and provides a simple programming interface for processing vast amounts of messages. Celery is used by many companies because it is easy to set up and has excellent performance. It can be configured to work with multiple broker services such as RabbitMQ, Redis, and Amazon SQS. Additionally, Celery integrates with Django, Flask, and other web frameworks. This makes it an ideal choice for busy web applications that need to process large amounts of data quickly.


NSQ is an excellent choice for a message queue for a number of reasons. First, it is designed to operate at scale. This means that it can easily handle a large number of messages and process them quickly. Second, it is open source, which means that anyone can contribute to the development of the software and improve its performance. Finally, NSQ is a modern message queue that uses a distributed memory system, which makes it more reliable and efficient than traditional message queues. As a result, NSQ is an ideal choice for a message queue for any business that needs to process a large number of messages quickly and reliably.


Redisson is a high performance Redis Java client with features of an in-memory data grid. It is very simple to learn and very easy to use. Redisson provides a number of features that are not available in other Redis clients, including: distributed locks, pub/sub, transactions, atomic variables, and object mapped caching. In addition, Redisson is fully compatible with all major Redis versions and supports both standalone and sentinel modes. As a result, Redisson is the most advanced and easiest Redis Java client available.
