Apache Pulsar is a distributed, open source pub-sub messaging and streaming platform for real-time workloads, managing hundreds of billions of events per day.
ØMQ is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker.
Apache ActiveMQ is the most popular and powerful open source messaging and Integration Patterns provider.
nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies.
Dedicated platform to send and receive messages within your applications. It has simple REST API and clean web UI. It allows to control access to your queues with managed access tokens.


Zeplo lets developers add retry, delay, queue and schedule to HTTP endpoints without setting up Redis, RabbitMQ or SQS. Just prefix any HTTP endpoint with zeplo.to/ and the request is queued.
