a realtime distributed messaging platform

by Matt Reiferson @imsnakes and Jehiah Czebotar @jehiah


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. See features & guarantees.

Operationally, NSQ is easy to configure and deploy (all parameters are specified on the command line and compiled binaries have no runtime dependencies). For maximum flexibility, it is agnostic to data format (messages can be JSON, MsgPack, Protocol Buffers, or anything else). Official Go and Python libraries are available out of the box and, if you’re interested in building your own client, there’s a protocol spec (see client libraries).

NSQ was designed and developed by Matt Reiferson (@imsnakes) and Jehiah Czebotar (@jehiah) but wouldn’t have been possible without the support of bitly and all our contributors.
