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][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 (as well as many other [client libraries][client_libraries]), and if you're interested in building your own, there's a [protocol spec][protocol]. We publish [binary releases][installing] for Linux, Darwin, FreeBSD and Windows, as well as an official [Docker image][docker_deployment]. NOTE: master is our *development* branch and may not be stable at all times. ## In Production <a href="https://bitly.com/"><img src="https://nsq.io/static/img/bitly_logo.png" width="84" align="middle"/></a> <a href="https://www.life360.com/"><img src="https://nsq.io/static/img/life360_logo.png" width="100" align="middle"/></a> <a href="https://www.simplereach.com/"><img src="https://nsq.io/static/img/simplereach_logo.png" width="136" align="middle"/></a> <a href="https://moz.com/"><img src="https://nsq.io/static/img/moz_logo.png" width="108" align="middle"/></a> <a href="https://segment.com/"><img src="https://nsq.io/static/img/segment_logo.png" width="70" align="middle"/></a> <a href="https://eventful.com/events"><img src="https://nsq.io/static/img/eventful_logo.png" width="95" align="middle"/></a><br/> <a href="https://www.energyhub.com/"><img src="https://nsq.io/static/img/energyhub_logo.png" width="99" align="middle"/></a> <a href="https://project-fifo.net/"><img src="https://nsq.io/static/img/project_fifo.png" width="97" align="middle"/></a> <a href="https://trendrr.com/"><img src="https://nsq.io/static/img/trendrr_logo.png" width="97" align="middle"/></a> <a href="https://reonomy.com/"><img src="https://nsq.io/static/img/reonomy_logo.png" width="100" align="middle"/></a> <a href="https://hw-ops.com/"><img src="https://nsq.io/static/img/heavy_water.png" width="50" align="middle"/></a> <a href="https://www.getlytics.com/"><img src="https://nsq.io/static/img/lytics.png" width="100" align="middle"/></a><br/> <a href="https://mediaforge.com/"><img src="https://nsq.io/static/img/rakuten.png" width="100" align="middle"/></a> <a href="https://wistia.com/"><img src="https://nsq.io/static/img/wistia_logo.png" width="140" align="middle"/></a> <a href="https://stripe.com/"><img src="https://nsq.io/static/img/stripe_logo.png" width="96" align="middle"/></a> <a href="https://www.shipwire.com/"><img src="https://nsq.io/static/img/shipwire_logo.png" width="97" align="middle"/></a> <a href="https://digg.com/"><img src="https://nsq.io/static/img/digg_logo.png" width="97" align="middle"/></a> <a href="https://www.scalabull.com/"><img src="https://nsq.io/static/img/scalabull_logo.png" width="97" align="middle"/></a><br/> <a href="https://www.soundest.com/"><img src="https://nsq.io/static/img/soundest_logo.png" width="96" align="middle"/></a> <a href="https://www.docker.com/"><img src="https://nsq.io/static/img/docker_logo.png" width="100" align="middle"/></a> <a href="https://www.getweave.com/"><img src="https://nsq.io/static/img/weave_logo.png" width="94" align="middle"/></a> <a href="https://www.augury.com/"><img src="https://nsq.io/static/img/augury_logo.png" width="97" align="middle"/></a> <a href="https://www.buzzfeed.com/"><img src="https://nsq.io/static/img/buzzfeed_logo.png" width="97" align="middle"/></a> <a href="https://eztable.com/"><img src="https://nsq.io/static/img/eztable_logo.png" width="97" align="middle"/></a><br/> <a href="https://www.dotabuff.com/"><img src="https://nsq.io/static/img/dotabuff_logo.png" width="97" align="middle"/></a> <a href="https://www.fastly.com/"><img src="https://nsq.io/static/img/fastly_logo.png" width="97" align="middle"/></a> <a href="https://talky.io/"><img src="https://nsq.io/static/img/talky_logo.png" width="97" align="middle"/></a> <a href="https://groupme.com/"><img src="https://nsq.io/static/img/groupme_logo.png" width="97" align="middle"/></a> <a href="https://wiredcraft.com/"><img src="https://nsq.io/static/img/wiredcraft_logo.jpg" width="97" align="middle"/></a> <a href="https://sproutsocial.com/"><img src="https://nsq.io/static/img/sproutsocial_logo.png" width="90" align="middle"/></a><br/> <a href="https://fandom.wikia.com/"><img src="https://nsq.io/static/img/fandom_logo.svg" width="100" align="middle"/></a> <a href="https://gitee.com/"><img src="https://nsq.io/static/img/gitee_logo.svg" width="140" align="middle"/></a> <a href="https://bytedance.com/"><img src="https://nsq.io/static/img/bytedance_logo.png" width="140" align="middle"/></a> <a href="https://www.tokopedia.com/"><img src="https://nsq.io/static/img/tokopedia_logo.svg" width="145" align="middle"/></a><br/> <a href="https://www.kuafood.com/"><img src="https://nsq.io/static/img/kuafood_logo.png" width="145" align="middle"/></a><br/> ## Code of Conduct Help us keep NSQ open and inclusive.
