What is it?

NSQ is a message queue for passing messages between services in real time. Its topologies are distributed and decentralized, so there is no single broker whose failure takes the system down, and it aims for high availability with reliable delivery.

Deployment is simple: all parameters are set on the command line and the compiled binaries have no runtime dependencies. NSQ is agnostic to payload format, so messages can be JSON, MsgPack, Protocol Buffers or anything else. Official Go and Python client libraries are provided, along with many community clients and a documented TCP protocol for writing new ones.

Binary releases are published for Linux, Darwin, FreeBSD and Windows, and an official Docker image is available.
