Apache Qpid implements the latest AMQP specification, the first open standard for enterprise messaging, and provides transaction management, queuing, distribution, security, management, clustering, federation and heterogeneous multi-platform support and a lot more.

Apache Qpid - AMQP Enterprise Messaging Implementation.

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 - Messaging Library

Pulsar is a distributed pub-sub messaging platform with a very flexible messaging model and an intuitive client API. It is horizontally scalable (Millions of independent topics and millions of messages published per second), Strong ordering and consistency guarantees, Low latency , REST API, Geo Replication and lot more.

ActiveMQ Apollo is a faster, more reliable, easier to maintain messaging broker built from the foundations of the original ActiveMQ. It accomplishes this using a radically different threading and message dispatching architecture. Like ActiveMQ, Apollo is a multi-protocol broker and supports STOMP, AMQP, MQTT, Openwire, SSL, and WebSockets.

A simple, fast, robust job/task queue for Node.js, backed by Redis.Bee-Queue is meant to power a distributed worker pool and was built with short, real-time jobs in mind. A web server can enqueue a job, wait for a worker process to complete it, and return its results within an HTTP request. Scaling is as simple as running more workers.

Pulsar is a distributed pub-sub messaging platform with a very flexible messaging model and an intuitive client API. It has run in production at Yahoo scale for over 3 years, with millions of messages per second across millions of topics. It is Horizontally scalable, Low latency, High throughput, Multi-tenancy, Geo-replication, Transparent batching of messages, Transparent handling of partitioned topics, REST API for provisioning, admin and stats and lot more.

MBassador is a light-weight, high-performance event bus implementing the publish subscribe pattern. It is designed for ease of use and aims to be feature rich and extensible while preserving resource efficiency and performance. The core of MBassador is built around a custom data structure that provides non-blocking reads and minimized lock contention for writes such that performance degradation of concurrent read/write access is minimal.

The Spread toolkit provides a high performance messaging service that is resilient to faults across local and wide area networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast, group communication, and point to point support. Spread services range from reliable messaging to fully ordered messages with virtual synchrony delivery guarantees.
