A cross-platform C++ library to publish and subscribe for events. Applications communicate using ZeroMQ, discover each other automatically through the integrated ZeroConf protocol or through explicit addressing using hostname and port. A defined vocabulary defines semantics for the published events, provided by ZeroBuf or using a simple Serializable interface. An optional http::Server provides a web service API in C++ applications.


ZeroEQ provides the following major features:

  • Publish events using zeroeq::Publisher
  • Subscribe to events using zeroeq::Subscriber
  • Web service GET and PUT events using zeroeq::http::Server using REST and JSON
  • Asynchronous, reliable transport using ZMQ
  • Automatic publisher discovery using Zeroconf
  • Serialization of events using ZeroBuf
  • List of RFCs

Building from Source

ZeroEQ is a cross-platform library, designed to run on any modern operating system, including all Unix variants. It requires a C++11 compiler and uses CMake to create a platform-specific build environment. The following platforms and build environments are tested:

  • Linux: Ubuntu 16.04, RHEL 6.8 (Makefile, Ninja)
  • Mac OS X: 10.9 (Makefile, Ninja)

ZeroEQ requires the following external, pre-installed dependencies:

  • ZeroMQ 4.0 or later
  • Boost (tested with 1.54) for unit tests

Building from source is as simple as:

git clone
mkdir ZeroEQ/build
cd ZeroEQ/build
cmake -GNinja ..
