Based on the most widely used Node on the Network, OpenNode2 now freely available for download

Built by the most recognizable and trusted  company on the Exchange Network, OpenNode2 is the free, tried-and-true choice for your next generation Exchange Network Node.


Reliable and Proven Design
With an installation base of more than 30 state, county, and tribal environmental agencies across the country, the technology behind OpenNode2 is the trusted choice for automating data exchange.
Pre-packaged Software for the Most Common Flows
OpenNode2 comes with several data exchange “plugins,” modular components for sending and receiving specific types of environmental data. Some plugins are ready to flow after only configuring a few simple settings. Plugins are “hot swappable,” allowing for upgrading or adjusting a flow without interrupting Node activity.
Ready for your Environment
OpenNode2 is available in Microsoft .NET and Java J2EE environments and supports all major databases. Flexible deployment options allow for single-server or distributed installations to meet the needs of a variety of agencies.
