NATS Replicator

License ReportCard Build

This project implements a multi-connector bridge, copier, replicator between NATS and NATS streaming endpoints.


  • Arbitrary subjects in NATS, wildcards for incoming messages
  • Arbitrary channels in NATS streaming
  • Optional durable subscriber names for streaming
  • Configurable std-out logging
  • A single configuration file, with support for reload
  • Optional SSL to/from NATS and NATS streaming
  • HTTP/HTTPS-based monitoring endpoints for health or statistics


The replicator runs as a single process with a configured set of connectors mapping a between a NATS subject or a NATS streaming channel. Each connector is a one-way replicator.

Connectors share a NATS connection and an optional connection to the NATS streaming server.

Request-reply is not supported.

The replicator is configured with a NATS server-like format, in a single file and uses the NATS logger.

An optional HTTP/HTTPS endpoint can be used for monitoring.


  • Integrate with coveralls
