Disque vs NSQ: What are the differences?
Developers describe Disque as "In-memory, distributed job queue". Disque is an ongoing experiment to build a distributed, in-memory, message broker. Its goal is to capture the essence of the "Redis as a jobs queue" use case, which is usually implemented using blocking list operations, and move it into an ad-hoc, self-contained, scalable, and fault tolerant design, with simple to understand properties and guarantees, but still resembling Redis in terms of simplicity, performance, and implementation as a C non-blocking networked server. On the other hand, NSQ is detailed as "A realtime distributed messaging platform". NSQ is a realtime distributed messaging platform designed to operate at scale, handling billions of messages per day. It promotes distributed and decentralized topologies without single points of failure, enabling fault tolerance and high availability coupled with a reliable message delivery guarantee.

Disque and NSQ can be primarily classified as "Message Queue" tools.
Disque and NSQ are both open source tools. NSQ with 15.5K GitHub stars and 2.04K forks on GitHub appears to be more popular than Disque with 7.35K GitHub stars and 516 GitHub forks.
