OpenNMS is the world's first enterprise grade network management application platform developed under the open source model.

Well, what does that mean?

• World's First

  The OpenNMS Project was started in July of 1999 and registered on SourceForge in March of 2000. It has years of experience on the alternatives.

• Enterprise Grade

  It was designed from "day one" to monitor tens of thousands to ultimately unlimited devices with a single instance. It brings the power, scalability and flexibility that enterprises and carriers demand.

• Application Platform

  While OpenNMS is useful "out of the box," it is designed to be highly customizable to create an unique and integrated management solution.

• Open Source

  OpenNMS is 100% Free and Open Source software, with no license fees, software subscriptions or special "enterprise" versions.
