Preferred for C
NNG
A modern C implementation with an updated API, broad transport support, and compatibility help for existing nanomsg applications.
Start with NNGThe Scalability Protocols
Patterns for programs that need to talk.
nanomsg is a family of lightweight messaging protocols for building distributed systems. Start with the communication pattern you need; choose the implementation that fits your language.
Protocol first
A small vocabulary for distributed systems.
Each protocol describes how peers exchange messages. Implementations share this model, letting you make a deliberate choice about language, API, and lifecycle without losing sight of the topology.
01
PAIR
Direct one-to-one communication between two peers.
02PUB / SUB
Publish messages to every interested subscriber.
03REQ / REP
Route requests to services and receive replies.
04PUSH / PULL
Distribute work and aggregate messages.
05BUS
Exchange messages in a simple many-to-many mesh.
06SURVEYOR / RESPONDENT
Ask many peers a question and collect their answers.
Choose your implementation
Use your favorite language. Interoperate everywhere.
Preferred pure Go implementation
mangos
A native Go implementation of the protocol family, built for Go applications rather than as a wrapper around a C library.

libnanomsg
The original C implementation. It remains available for existing applications and the language bindings built around its stable API.

nng-rs
A safe, idiomatic Rust wrapper for NNG. It is independently maintained, with its own release lifecycle.
