Scalable, fault-tolerant messaging for billions of events daily
NSQ delivers real-time, distributed messaging with no single point of failure, supporting billions of messages daily, easy CLI deployment, language-agnostic payloads, and native Go/Python client libraries.
NSQ is a real-time distributed messaging platform built for high‑throughput environments. It targets developers and operations teams building microservices, event‑driven pipelines, and analytics systems that must handle billions of messages per day while maintaining fault tolerance and high availability.
The system uses a decentralized topology that eliminates single points of failure. Messages are stored in memory and on local disk, providing at‑least‑once delivery guarantees. Configuration is entirely command‑line driven, and the compiled binaries have no runtime dependencies. NSQ ships binaries for Linux, macOS, FreeBSD, Windows, and an official Docker image, making deployment straightforward across cloud, on‑prem, or edge environments. Payloads are format‑agnostic, and a rich ecosystem of client libraries—including official Go and Python bindings—lets applications speak the protocol in any language.
Because NSQ relies on simple binaries and a clear protocol spec, teams can scale clusters horizontally, monitor health with external tools, and integrate seamlessly with existing logging or monitoring stacks.
When teams consider NSQ, these hosted platforms usually appear on the same shortlist.
Fully managed message queuing service for decoupling and scaling distributed applications
Fully managed enterprise message broker for decoupling applications via message queues and publish/subscribe topics
Global messaging service for event ingestion and fan‑out
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Log aggregation across data centers
Collects billions of log entries in real time, delivering them to processing services with fault tolerance.
User activity stream for a social platform
Routes click and interaction events to recommendation engines, scaling with traffic spikes without downtime.
IoT sensor data ingestion
Buffers high-velocity sensor messages, decoupling devices from analytics pipelines while preserving delivery guarantees.
Background job dispatch for a web service
Distributes work items to worker pools, enabling horizontal scaling and graceful node failures.
NSQ guarantees at-least-once delivery; messages persist until a consumer acknowledges them.
NSQ runs as compiled binaries with command-line flags, available for Linux, macOS, FreeBSD, Windows, and as an official Docker image.
Official client libraries exist for Go and Python, and many community libraries cover Java, Ruby, Node.js, and more.
NSQ stores messages in memory and on local disk; it does not depend on external databases for core operation.
Its decentralized design eliminates single points of failure; multiple nsqd instances and nsqlookupd services replicate state and route messages.
