Several free Exchange Network software products are available. These pre-developed solutions allow Partners to take advantage of others’ development work and lessons learned, so they are often more cost-effective than independently building new tools from scratch. Partners should be aware that even these solutions may require customization to work within an individual organization’s technology environment and infrastructure. Funding to support this work has been and continues to be made available through EPA’s Exchange Network Grant Program.

OpenNode2 and EN-Node Plugins are available for a wide variety of data flows.
Node Clients (also known as Network Clients) can interact with Exchange Network Nodes by submitting data to Nodes and retrieving data from Nodes. Node Clients provide the following benefits:
- An easy-to-use interface for interacting with Nodes
- Semi-automated alternative to a fully functioning Node that allows users to submit data to or download data from a Partner’s Node
- Assists in testing the development and implementation of a Node
Node Clients cannot respond to data queries from other Nodes and, therefore, cannot publish on-demand data on the Network. They may be a cost-effective solution for Partners who do not have a compelling business need to publish their data. Node or Node Client: To be or not to be describes the differences between a Node and a Client.
These Node Clients are available online:
- EN Services Center: Network Client hosted by EPA that makes submitting data to EPA Nodes easier.
- EN Browser: A special Network Client that can be used to retrieve data from any Exchange Network data publisher.
- NodeClientLite2: A Network Client developed by Windsor Solutions, Inc., that runs as a desktop application. Also includes an integrated add-on to view spatial data and facility data.
- EN-Node – Node Client: The EN-Node software includes a bundled Node Client. This Node Client runs as a web application, so in order to run this option, the user will need to install the application on a web server.
