Fast, lightweight messaging library that allows you to design complex communication system without much effort

What is ZeroMQ?

The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
ZeroMQ is a tool in the Message Queue category of a tech stack.
ZeroMQ is an open source tool with 5.3K GitHub stars and 1.6K GitHub forks. Here’s a link to ZeroMQ's open source repository on GitHub

ZeroMQ Alternatives & Comparisons

What are some alternatives to ZeroMQ?
RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
Amazon SQS
Transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. With SQS, you can offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use.
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.
